Abstract:
Although many problems in aluminium matrix composites have been solved, there are still many difficulties and challenges that need to be solved. In this work, graphene reinforced aluminum matrix composites are prepared by hot isostatic pressing and vacuum sintering. The microstructures of composite powders and composites were studied by means of scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The effects of different ball milling parameters on the microstructures of composite powders were analyzed. The particle size of graphene coated aluminium composite powder increases with the increase of ball-to-material ratio. With the increase of milling time, graphene was gradually dispersed and coated on the aluminium powder particles, and the aluminium powder particles could be completely coated. with the increase of the speed, the large particles are extruded, sheared and the particles become smaller. The internal micro-deformation characteristics of graphene reinforced aluminium matrix composites were analyzed in detail.

Abstract:
The performances of aluminum /vinylester particulate-composites were studied in detail in order to investigate its suitability for engineering applications. This study examined the suitability of atomised aluminum particles for particulate reinforcement of a vinyl ester resin. Mechanical properties were obtained for the composite by testing various percentages of aluminium powder (75-150 m) and vinylester resin. It has been found that the inclusion of Al powder has not significantly changed the properties of vinylester resin, however an improvement in the ductility of the composite has been recorded. The optimal performances of the composite were exhibited by 15% Al composition. The properties of the particulate composites were modeled using numerous empirical models. Unfortunately a significant difference was found between some of the experimental and predicted properties of the Al/vinylester particulate composite. This paper intends to detail the variation of mechanical properties with the change of Al volume fraction in the composite and the performances of empirical models in prediction of the properties of particulate composites.

Material scientistss alwayss face a challenges when it comess to the tribologicals and mechanicals propertiess of aluminium, as it exudess rather poors behaviours in these aspectss. Hences this works aims to improves the mechanicals and corrosives resistances of Aluminiums by reinforcings with aluminum oxides and Nickel throughs stir casting usings vortex techniques. Al-Ni-Al2O3 composites with percentages of Ni fixed at 20 % and Al2O3 differed through 4-8% in incrementss of 2 wt. % . Composites material was prepareds by stir castings using vortex techniques. The hardness value of the aluminiums matrix composites improved with increaseds percentages of Al2O3, maximums increase was obtaineds for 8% Al2O3 composite, viewing an increases of about 55%. A generals corrosions and erosion-corrosions for the Al-20%Ni bases alloys and the prepareds composites were carrieds out in 3.5wt% NaCl solutions as corrosives mediums for general corrosions while in erosion-corrosions with impacts angles 90° in slurry solutions ( 1wt%SiO2 sand in 3.5wt% NaCl solution as the erodent). It was founds that the general corrosions rates for composite specimens is lower than thats of the bases alloy (Al-20%Ni). In case of erosion-corrosion resultss, it was founds that the erosion corrosions resistances property of the prepareds composites improveds significantlys with the increaseds percentages of Al2O3. There wass a noticeable improvements in the corrosion resistances of the aluminiums composites compareds to its purest forms, owing to the presences of nickel. Howevers, the increases in Al2O3 percentages decrease the corrosions rates. The extreme decreases was obtaineds for 8% Al2O3 composites, with a decreases of 26% corrosion rates in (mpy) unit for composites material is lowers than that of the bases alloys.

Abstract:
The increasing concern for sustainable materials and waste management has led to innovative approaches in material science. This study explores the potential benefit of aggregate waste in the production of aluminum composites practicing powder metallurgy techniques. The aim is to investigate the feasibility of incorporating bone material into aluminium matrices to enhance the composite’s mechanical properties. The research involves several key steps. Firstly, waste bone material is collected and processed to obtain a fine powder suitable for powder metallurgy. Various techniques such as grinding, milling, or pulverization are employed to achieve the desired particle size distribution. Next, the bone powder is mixed with aluminium powder in predetermined ratios to create composite blends. The composite blends are then subjected to compaction using powder metallurgy techniques, including cold pressing and sintering. The compaction process aims to consolidate the powders and facilitate the formation of a solid composite structure. The aluminum composites mechanical characteristics are then assessed. The effects of incorporating bone material are assessed using tests on tensile strength, ductility, hardness, and other relevant mechanical properties. Comparative analysis is performed between the composites with bone material and traditional aluminium composites to assess any improvements or changes in performance.

Abstract:
Aluminium-matrix composite is one of the most preferred engineering materials and is known for its potential benefits, such as lightweight nature, high specific stiffness, superior strength, machinability, etc. The metal–matrix composites are very attractive for critical applications: Aerospace field, defense deployments, automotive sector, marine industry. In the present work, novel Physella Acuta Snail Shell particle reinforced aluminium metal–matrix composites are developed to facilitate cost-effective and sustainable manufacturing. These green composites are developed by stir-casting with LM0 as matrix material and snail shell as reinforcement with a distinct percentage (by weight) of inclusion. The influence of snail shells is analyzed through tribological, morphological, and corrosion studies. Aluminium–matrix composite Al98SNS2 with 98% (by weight) aluminium matrix and 2% (by weight) snail shell reinforcement exhibits superior performance in all investigations. Al98SNS2 composite exhibits the least wear rate in the atmosphere of deionized water and 3.5% NaCl. Corrosion deteriorates the surface roughness irrespective of the percentage of incorporation of snail shell reinforcement. However, the deterioration is minimal in Al98SNS2. The current research findings indicate that the incorporation of snail shell in aluminum metal–matrix composites promotes cost-effective, sustainable, and eco-friendly manufacturing.

Abstract:
This paper investigates the effect of nanosilica on impact and energy absorption properties of sandwich foam-fibre composites. The materials used in this study are closed-cell aluminum (Al) foam (as the core material) that is sandwiched in between nanomodified basalt fiber reinforced polymer (as the face-sheets). The face sheets were made of Basalt Fibre, nanosilica and epoxy polymer matrix. The sandwich composite structures are known to have the capability of resisting impact loads and good in absorbing energy. The objective of this paper is to determine the influence of closed-cell aluminum foam core and nanosilica filler on impact properties and fracture behavior of basalt fibre reinforced polymer (BFRP) sandwich composites when compared to the conventional glass fibre reinforced polymer (GFRP) sandwich composites. The drop impact tests were carried out to determine the energy absorbed, peak load and the force-deflection behaviour of the sandwich composite structure material. The results showed that the nanomodified BFRP-Al foam core sandwich panel exhibited promising energy absorption properties, corresponding to the highest specific energy absorption value observed. Also, the result indicates that the Aluminium Foam BFRP sandwich composite exhibited higher energy absorption when compared to the Aluminium foam GFRP sandwich composite.

Abstract:
Metal matrix composite materials are a novel material generation capable of handling the implementation of advanced technology's growing needs. Aluminium-based metal matrix composites are widely used in automobiles and aerospace, as well as other industries, including defence and marine systems, due to their relatively low processing costs as compared to other matrices such as magnesium, copper, titanium, and zinc. Ceramic particles were shown to improve mechanical properties like hardness and tensile strength. The product's compactness and price, however, were both boosted. Agricultural waste materials are widely available today in significant amounts, and researchers have focused on using wastes as reinforcing fillers in composites to counteract pollution. Rice husk ash added to an aluminium alloy matrix increases the composite's mechanical properties while also increasing its wear resistance. According to scanning electron micrographs of the composite, the ash from rice husks is evenly distributed all over the aluminium matrix. Wear can vary from micro-cutting to oxidation at high temperatures in an aluminium alloy. Strain fields are produced and composite material wear resistance is improved due to the difference in coefficients of thermal expansion between the matrix and reinforcing materials. This study focuses on the production process, properties, and performance of an aluminium alloy composite incorporating rice husk ash, which has high hardness as well as wear resistance.

Abstract:
La plupart des composites à matrice métalliques étudiés à l'heure actuelle sont élaborés par trois technologies principales, dont le coût relativement élevé limite les domaines d'utilisation. Pour palier cet inconvénient, nous avons travaillé à mettre au point un procédé de cofilage en phase solide. L’évolution du procédé nous a permis de résoudre les problèmes d'imprégnation du renfort par la matrice. Dans le cadre de l'optimisation des étapes de fabrication, nous avons étudié l'influence des paramètres suivants sur le comportement et les mécanismes d'endommagement du matériau: longueur des fibres, orientation du renfort et fraction volumique locale. Pour cela nous avons développé une démarche de type micro-macro fondée sur la théorie d'inclusion équivalente d'Eshelby. Nous modélisons ainsi l'influence de la microstructure sur les caractéristiques élastiques, les coefficients de dilatation et la surface seuil d'écoulement. Des calculs par éléments finis sur cellules de base à trois phases complète cette approche. Nous regardons l'influence de la répartition des fibres sur le développement de la plasticité locale. Une configuration de fibres proches de leurs voisines a un rôle prépondérant sur la propagation de l'endommagement qui se produit en tête de fibre. Nous proposons un critère analytique d'initiation de cet endommagement qui prend en compte la distribution de fraction volumique locale dans le matériau. Les résultats sont comparés à des essais de traction dans l'enceinte du microscope électronique à balayage, ou nous pouvons suivre les différentes étapes du processus de rupture. L’outil analytique développé est intégré dans une démarche originale de détermination d'une statistique d'endommagement pour une structure. Nous pouvons, ainsi, donner localement la probabilité d'endommagement d'un volume de composite en fonction de l'observation de ses distributions de microstructure, et du chargement

Abstract:
Les matériaux composites à matrice métallique (CMM) sont actuellement étudiés pour être utilisés dans de nombreux domaines d’application. L’une des applications potentielles concerne leur utilisation en tant que drain thermique pour les modules de puissance. Pour cette application, deux conditions sont requises : une conductivité thermique (CT) élevée pour évacuer la chaleur générée par la puce électronique et un coefficient d’expansion thermique (CTE) proche du substrat céramique (2-8×10-6 /K) utilisé dans le module de puissance.Ainsi des matériaux composites à matrice aluminium (Al : CT de 217 W/m.K et CTE de 24×10-6 /K) et à renfort plaquette de graphite (GF : CT de 1000 W/m.K et CTE de -1×10-6 /K dans le plan de la plaquette) ont été élaborés. Ces matériaux composites ont été fabriqués par Métallurgie des Poudres (MP) conventionnelle mais aussi par un procédé original nommé Flake Powder Metallurgy (FPM). Ce procédé, qui consiste à utiliser une poudre métallique à morphologie plaquette, a permis d’optimiser l’orientation des renforts plaquette dans un plan perpendiculaire à la direction de densification sous l’action d’une pression uniaxiale. De plus, ce procédé a permis d’obtenir une meilleure adhésion entre la matrice et le renfort comparé aux matériaux composites élaborés par MP conventionnelle. Cela a abouti à une amélioration de la CT qui est passée de 400 W/m.K à 450 W/m.K pour un taux de renfort de 50%vol. Néanmoins, concernant la dilatation thermique, des CTE de 21,8×10-6 /K et 21,7×10-6 /K ont été obtenus par MP et FPM respectivement, ce qui est incompatible avec l’application visée.Pour surmonter cette problématique, des matériaux composites à renfort multiple ont été élaborés par frittage en phase liquide. Ainsi des fibres de carbone (FC) ont été rajoutées à l’aluminium et aux plaquettes de graphite. L’ajout de ce second renfort au graphite a permis de diminuer de manière importante le CTE des composites Al/(GF+FC) avec une faible proportion en FC tout en maintenant une haute CT. De plus les matériaux composites Al/(GF+FC) présentent des CTE nettement inférieurs aux composites Al/FC avec un %vol. de FC équivalent. Ainsi des matériaux composites Al/(GF+FC) ont été élaborés par frittage en phase liquide permettant d’obtenir une CT de 400 W/m.K (comparable à la CT du cuivre) et un CTE de 8×10-6 /K (comparable au CTE de l’alumine). De plus la légèreté de l’aluminium confère aux matériaux composites Al/C une faible densité (d=2,4). Par conséquent, les matériaux développés dans cette étude sont prometteur en tant que drain thermique léger, notamment dans le domaine de l’électronique embarquée
Many carbon/metal composites are currently used in several applications. One of them concerns their use as heat sinks in microelectronics. Concerning this application, two conditions are required: a high thermal conductivity (TC) in order to evacuate the heat generated by the electronic chip and a coefficient of thermal expansion (CTE) similar to the used material type of the electronic device (2-8×10-6 /K).Therefore, graphite flakes (GF; TC: 1000 W/m.K and CTE: -1×10-6 /K in the graphite plane) reinforced aluminum matrix (Al; TC: 217 W/m.K and CTE: 25×10-6 /K) composites were fabricated. These composite materials were fabricated by Powder Metallurgy (PM) and Flake Powder Metallurgy (FPM). This process, which consist to use a flattened metallic powder, helped to improve the in-plane orientation (perpendicular to the pressure direction) of GF under uniaxial pressure. Moreover, this process provided a better Al-C interface thanks to a planar contact between the matrix and the reinforcements. This resulted in an improvement of the CT from 400 W/m.K to 450 W/m.K for a reinforcement content of 50 vol.%. Nevertheless, regarding thermal dilation, CTEs of 21.8×10-6 /K and 21.7×10-6 /K were obtained by MP and FPM respectively, which is incompatible with the intended application.To overcome this problem, composite materials with multiple reinforcement were developed by solid-liquid phase sintering. Then, carbon fibers (CF) have been added to aluminum and graphite flakes. The addition of CF to GF reinforcement reduced significantly the CTE of the Al/(GF+CF) composites with a small proportion of CF, while preserving a high TC. In addition, the Al/(GF+FC) composite materials have significantly lower CTEs than the Al/CF composites with a equivalent vol.% of CF. Therefore, Al/(GF+CF) composite materials were developed by solid-liquid phase sintering to obtain a TC of 400 W/m.K (comparable to the TC of copper) and a CTE of 8×10-6 /K (comparable to the CTE of alumina). In addition, the lightweight of aluminum gives composite materials Al/C a low density (d = 2.4 g/cm3). Therefore, the composite materials developed in this study are promising as a lightweight heat sink in microelectronic industries

Abstract:
The machining of aluminium 2618 particulate reinforced Metal Matrix Composite (MMC) with 18 vol. % silicon carbide (SiC) using cemented carbide cutting tools has been undertaken. Two grades of cemented carbide inserts, uncoated K68 grade and coated KC910 grade (coated with TiC and A1203) having negative and positive rake angles (with and without chip breaker) have been used to machine this material in order to understand the machining process, tool failure modes and wear mechanisms. Turning tests in the speed range 15 - 10 m/min have been carried out at 0.2,0.4 and 0.6 mm/rev feed rates and 2 mm and 4 mm depths of cut. Both cemented carbide tools have been shown to be capable of machining the MMC and give reasonable tool lives. Low speed and high feed rate are found to be a good combination in order to machine this material effectively. Coated KC910 grade inserts with negative rake angle gave the best performance. The use of a chip breaker has no significant effect on the machining process of the NMC because the material is one which inherently short chips due to ductility limitations caused by the particles. Tool failure mode studies showed that the tools failed by flank wear. Tool wear mechanism analysis indicated that abrasion wear was the tool life controlling factor under all cutting conditions. The tool wear is related to the direct contact between the abrasive hard SiC particles and the cutting edge and their relative motion to the rake and clearance face. Hence, the hardness of the SiC particles is a dominant factor for the tool wear. Two separatem odels of abrasio. n haye.b een suggested.B uilt-up edge (BUE) which has a distinct shape was more pro i1ounced at lower cutting speeds, high feed rates and greater depth of cut. The presence of BUE has been found to increase tool life and reduce tool wear but at the expense of surface finish. The increase in tool life or reduction in tool wear is likely due to the protective layer that the BUE formed on the tool surface preventing a direct contact between the tool and chip. Linear regression analysis showed that the value of Taylor exponent n is high (0.8-1.0) compared to the values of n (0.2-0.3) obtained when machining steel. This indicates that the tool life is less sensitive to cutting speed for MMC than it is for steel.

Abstract:
The aim of this study was to develop a new castable and heat treatable alloy, based on the A205 alloy composition, with improved thermal stability at 230 °C. Several unique combinations of alloying elements, chosen from groups IIIB, IVB and VB, up to 0.5 wt. %, were added to the A205 alloy. These elements were chosen to nucleate high temperature precipitates, with a cubic L12 structure. The additions were made in group of two, with one elements being always the zirconium. After 1000 hours holding at 230 °C, several of these alloys resulted to have better mechanical properties when compared to the A205 alloy. The IDEAL alloy was chosen and further studies were carried out. This alloy showed the same tensile proprieties of the A205 alloy at peak-aged condition, while at elevated temperature, the IDEAL alloy had 15 % improved UTS and YS. An investigation was carried out to understand the reasons of this improvement. Two strengthening mechanisms were found. Firstly, the microstructure of the alloy showed a reduced size of the Al-Cu precipitates. Secondly, two different high temperature precipitates were nucleated.

La présente étude traite de la durabilité (vieillissement) en milieu humide d'assemblages structuraux constituants les tuyères de propulseurs à poudre. Les matériaux utilisés sont un alliage d'aluminium et un matériau composite, collés ensemble par un adhésif polymère.
L'adhésif se révèle être la partie la plus sensible à un environnement aqueux. La cinétique de diffusion de l'eau dans la colle semble être décrite convenablement par le modèle mathématique de Carter et Kibler.
La diminution des propriétés mécaniques du polymère massique et des assemblages structuraux semble liée à la pénétration de l'eau. Un modèle permettant d'évaluer indirectement l'énergie d'adhésion, et par extrapolation la résistance des assemblages en fonction du temps de vieillissement a été élaboré à partir du faciès de rupture des éprouvettes et de la cinétique de diffusion d'eau. L'influence d'un traitement organosilane de la surface d'aluminium sablée sur la cinétique de dégradation en milieu humide des assemblages a ensuite été étudiée.

Abstract:
It is a major scientific challenge to develop the light-weight materials with high performance simultaneously in diverse applications ranging from civil engineering to defence. Numerical results for composite plates of 5.4-mm, 7.5-mm and 9.6-mm thick bioinspired composite plates were compared with corresponding bulk plates under the impact of a rigid hemi-spherical projectile at same impact velocities. The most significant improvement was recorded for the 5.4-mm thick nacre-like aluminium alloy composite plate, which was attributed to the larger area of plastic deformation due to the tablet arrangement. Experiments data were collected to validate the numerical simulation. It has been found that the nacre-like composites of different thickness had better ballistic behaviour than the bulk ones. The aim of this thesis is to give general background and research progress about natural nacre and the corresponding nacre-inspired artificial composites, to provide the basis for preparing the detailed experimental and numerical study on the ballistic performance of nacre-like aluminium alloy composites. My following ballistic experiments are to validate the numerical simulation results that the nacre-like composite plate has better ballistic performance at high velocity due to the tablets arrangement and plastic deformation. From previous simulation results, 5.4-mm nacre-like plate has shown a significant performance improvement compared with same thickness bulk plate owing to the hierarchical structure induced high energy absorptions. Hence, plate thickness and projectile velocity play a significant role on the performance improvement of the proposed nacre-like AA7075-T651 composites. Further experimental works are needed to assess other crucial parameters for modifying the mechanical behaviours of such bioinspired materials.

Johannesson, Birgir. "Internal stresses and the cyclic deformation of an aluminium matrix composite." Thesis, University of Surrey, 1992. http://epubs.surrey.ac.uk/843903/.

Full text
Abstract:
The development of internal stresses in planar random Saffil fibre reinforced aluminium with a range of fibre volume fractions has been studied theoretically and in monotonic and cyclic deformation (Bauschinger) experiments at room temperature and 77K. The conventional method of analysing Bauschinger experiments is extended to allow for a separation of the mean and thermal stresses. This analysis is applied to experimental results enabling the mean stress hardening rate and the magnitude of the thermal stress to be measured. The experimental results are compared with predictions of the mean field model, which is based on the Eshelby method of determining internal stresses. For that purpose the Eshelby S tensor for a planar random array of fibres is calculated. Because the aluminium/Saffil composites are not isotropic in the transverse directions, the plastic strain used in the calculations has to be determined experimentally. A method for quantifying the anisotropic plastic flow of the aluminium/Saffil composites is proposed and the results are used in calculations of the mean stress hardening rate. A comparison of predictions for the mean stress hardening rate with results of the experimental analysis proposed here shows that good agreement is obtained for low fibre volume fractions at 77 K. The results also show that relaxation of the mean stress increases with fibre volume fraction and that at 77 K the mean stress hardening rate is about a factor of two larger than at room temperature. The measurements of the thermal stresses obtained in the Bauschinger experiments are in quantitative agreement with results obtained in monotonic tests. The magnitude of the thermal stress at room temperature or 77 K is independent of fibre volume fraction and a comparison with predictions shows that relaxation of the thermal stress increases with fibre volume fraction. Cycling in the Bauschinger experiments reduces the thermal stress and hence the separation of the mean and thermal stresses is essential for a reliable measurement of the mean stress hardening rate. Matrix hardening contributes considerably to the overall hardening of the composite, both at room temperature and 77 K. The modified Orowan-Wilson model, which enables the plastic friction coefficient to be measured in copper-tungsten composites, has been applied to the aluminium\Saffil composites. The model requires both the mean stress and the peak stress curves obtained in Bauschinger experiments to be linear in plastic strain. Most of the peak stress curves for the aluminium/Saffil composites are non-linear but for the curves which are linear the predictions of the model are not in quantitative accord with experimental results. This may be because relaxation reduces the mean stress and the source shortening stress in different proportions. The diameter of the Saffil fibres is also close to the lower end of applicability of the model. The temperature dependence of the mean stress hardening rate suggests that relaxation is thermally activated. A model for relaxation of the mean stress is proposed. An equation is derived for the number of Orowan loops per fibre and it is assumed that the rate controlling mechanism of relaxation is cross slip of screw dislocations. The estimated activation energy is independent of fibre volume fraction but the activation volume decreases with increasing fibre volume fraction. The magnitudes of activation energy and activation volume support the assumptions of the model. A preliminary study on the early stages of fatigue shows that persistent slip bands form in the matrix of the aluminium/Saffil composites.

Abstract:
COVID-19, caused by the SARS-CoV-2 virus, was first reported in China in December 2019. The virus has spread rapidly around the world and is currently responsible for 500 million reported cases and over 6.4 million deaths. A risk assessment published by the Foods Standards Agency (FSA) in 2020 (Opens in a new window) concluded that it was very unlikely that you could catch coronavirus via food. This assessment included the worst-case assumption that, if food became contaminated during production, no significant inactivation of virus would occur before consumption. However, the rate of inactivation of virus on products sold at various temperatures was identified as a key uncertainty, because if inactivation does occur more rapidly in some situations, then a lower risk may be more appropriate. This project was commissioned to measure the rate of inactivation of virus on the surface of various types of food and food packaging, reducing that uncertainty. The results will be used to consider whether the assumption currently made in the risk assessment remains appropriate for food kept at a range of temperatures, or whether a lower risk is more appropriate for some. We conducted a laboratory-based study, artificially contaminating infectious SARS-CoV-2 virus onto the surfaces of foods and food packaging. We measured how the amount of infectious virus present on those surfaces declined over time, at a range of temperatures and relative humidity levels, reflecting typical storage conditions. We tested broccoli, peppers, apple, raspberry, cheddar cheese, sliced ham, olives, brine from the olives, white and brown bread crusts, croissants and pain au chocolat. The foods tested were selected as they are commonly sold loose on supermarket shelves or uncovered at deli counters or market stalls, they may be difficult to wash, and they are often consumed without any further processing i.e. cooking. The food packaging materials tested were polyethylene terephthalate (PET1) trays and bottles; aluminium cans and composite drinks cartons. These were selected as they are the most commonly used food packaging materials or consumption of the product may involve direct mouth contact with the packaging. Results showed that virus survival varied depending on the foods and food packaging examined. In several cases, infectious virus was detected for several hours and in some cases for several days, under some conditions tested. For a highly infectious agent such as SARS-CoV-2, which is thought to be transmissible by touching contaminated surfaces and then the face, this confirmation is significant. For most foods tested there was a significant drop in levels of virus contamination over the first 24 hours. However, for cheddar cheese and sliced ham, stored in refrigerated conditions and a range of relative humidity, the virus levels remained high up to a week later, when the testing period was stopped. Both cheddar cheese and sliced ham have high moisture, protein and saturated fat content, possibly offering protection to the virus. When apples and olives were tested, the virus was inactivated to the limit of detection very quickly, within an hour, when the first time point was measured. We suggest that chemicals, such as flavonoids, present in the skin of apples and olives inactivate the virus. The rate of viral decrease was rapid, within a few hours, for croissants and pain au chocolat. These pastries are both coated with a liquid egg wash, which may have an inhibitory effect on the virus. Food packaging materials tested had variable virus survival. For all food packaging, there was a significant drop in levels of virus contamination over the first 24 hours, in all relative humidity conditions and at both 6°C and 21°C; these included PET1 bottles and trays, aluminium cans and composite drinks cartons.

Abstract:
This report presents a review of quasi-static and dynamic properties of various iron, titanium, nickel, cobalt, and aluminum metals. The physical and mechanical properties of these materials are crucial for developing composite armoring systems vital for protecting critical bridges from terrorist attacks. When the wide range of properties these materials encompass is considered, it is possible to exploit the optimal properties of metal alloys though proper placement within the armoring system, governed by desired protective mechanism and environmental exposure conditions.
