Abstract:
Ceramic composite materials have been efficiently used for high-temperature structural applications with improved toughness by complementing the shortcomings of monolithic ceramics. In this study, the fracture characteristics and fracture mechanisms of ceramic composite materials were studied. The ceramic composite material used in this study is Nicalon ceramic fiber reinforced ceramic matrix composites. The tensile failure behavior of two types of ceramic composites with different microstructures, namely, plain-weave and cross-ply composites, was studied. Tensile tests were performed on two types of ceramic composite material specimens. Microstructure analysis using SEM was performed to find out the relationship between tensile fracture characteristics and microstructure. It was found that there was a difference in the fracture mechanism according to the characteristics of each microstructure. In this study, the results of tensile tests, failure modes, failure characteristics, and failure mechanisms were analyzed in detail for two fabric structures, namely, plain-weave and cross-ply structures, which are representative of ceramic matrix composites. In order to help understanding of the fracture process and mechanism, the fracture initiation, crack propagation, and fracture mechanism of each composite material are schematically expressed in a two-dimensional figure. Through these results, it is intended to provide useful information for the design of ceramic composite materials based on the mechanistic understanding of the fracture process of ceramic composite materials.

Abstract:
Laminated composites are the effective ways to toughen Al2O3 ceramics at present. The destruction process analysis of laminated ceramic composite is studied in this paper taking the Al2O3/ZrO2 ceramic composite as the example through the APDL programming. The micro model is established in ANSYS. And the failure stresses of each ply of the ceramic can be calculated by micromechanics method. Then the calculated failure stresses are compared to the simulated failure stresses. The micro model can visualize the destruction process of laminated ceramic composite. The failure criteria of composite material can be self-defining in ANSYS by using APDL. Some ideas of ANSYS application on composite material are given in this paper.

Abstract The study and development of ceramic composites are important because of the properties that these materials can provide, such as high dielectric constant and low dielectric loss in the RF and microwave range. Such characteristics make this type of material appropriate to several segments, such as in the telecommunication sector, especially in dielectric resonator antenna (DRA). Ceramic composites provide new materials with a range of properties that can be controlled through the phases to meet the specifications of a given application. This study aimed to synthesize and characterize the composite based on hexaferrite (BFO) and ceramics based on bismuth (BZN), aiming application as DRA. The composites were characterized by FTIR, XRD, and SEM. The composites presented a compact and heterogeneous microstructure, indicating that the sintering at 1000 °C/150 min was adequate for obtaining the ceramic composites; besides, BFO-BZNβ composite was shown to be less porous than the composite BFO-BZNα.

Abstract:
Ceramizable composite is a kind of polymer matrix composite that can turn into ceramic material at a high temperature. It can be used for the ceramic insulation of a metal conductor because of its processability. However, poor low-temperature ceramization performance is a problem of ceramizable composites. In this paper, ceramizable composites were prepared by using silicone rubber as a matrix. Ceramic samples were sintered at different temperatures no more than 1000 °C, according to thermogravimetric analysis results of the composites. The linear contraction and flexural strength of the ceramics were measured. The microstructure and crystalline phase of ceramics were analyzed using scanning electron microscope (SEM) and X-ray diffraction (XRD). The results show that the composites turned into ceramics at 800 °C, and a new crystal and continuous microstructure formed in the samples. The flexural strength of ceramics was 46.76 MPa, which was more than twice that of similar materials reported in other research sintered at 1000 °C. The maximum flexural strength was 54.56 MPa, when the sintering temperature was no more than 1000 °C. Moreover, glass frit and nano silica played important roles in the formation of the ceramic phase in this research. A proper content of nano silica could increase the strength of the ceramic samples.

Abstract:
The silicon nitride ceramics are usually known as strongly refractory and enduring materials and have typical electrically insulating properties. If the reinforcing phase of ceramic composite (that is mainly put in the material to improve mechanical properties) is a good electrical conductor, it is worth to investigate the composite in electrical aspect. In this work carbon nanotubes, black-carbon and graphite were added to the basic silicon nitride ceramic and the electrical conductivity of the prepared carbon-ceramic composites was determined. The conductivity of the ceramic composites with different type and concentration of the carbon additives was observed by applying four point DC resistance measurements. Insulator and conductor composites in a wide conductivity range can be produced depending on the type and quantity of the additives. The additive types as well as the sintering parameters have influence on the basic electrical properties of the conductor composites.

Abstract:
By using the active filler controlled polymer pyrolysis, new and cost-effective composite materials can be obtained. In this work, ceramic matrix composites were prepared by using this precursor route, using a polysiloxane network filled with metallic niobium and aluminum powders as active fillers. The mixtures were blended, uniaxially warm pressed, and pyrolyzed in flowing argon at 1400 °C. Porous ceramic preforms were infiltrated with a LZSA glass material, in order to improve the density of a porous composite material. The properties of the pyrolyzed composite material and the effect of the LZSA infiltration on the Al2O3-NbC-SiOC ceramic composite material were investigated. The results have showed that the infiltration processes has improved the physical and mechanical properties of the composite material.

The work presents the research results of modern composite materials. The matrix material was EN AC AlSi12 alloy while the reinforcement ceramic preforms, obtained through sintering process of Al2O3 Alcoa CL 2500 powder with addition of carbon fibers as pore forming agent burned out during sintering. The composites were produced with use of porous material pressure infiltration method. The main limitation of base technology is a difficulty in obtaining composite materials with volumetric participation of ceramic phase in amount not less than 20%. Obtained on the base of ceramic preforms composite materials were tested with scanning electron microscopy. Additionally, hardness and tensile test was performed for acquired materials. Achieved results indicate the possibility of producing, with use of pressure infiltration method, porous preforms composed of Al2O3 particles, new composite material with desired microstructure and properties, being a cheaper alternative for materials with base of ceramic fibers.

The demand for new materials in medicine is on the increase today. Long-lasting implants (joint prostheses, dentistry implants), made typically of metals and their alloys, are characterized with high mechanical properties, however their corrosion resistance and biocompatibility are relatively low. One of the methods to ensure particular functional properties is to employ composite implants, combining improved mechanical properties of metallic material with biocompatibility of ceramic materials. The study aimed to develop and analyse properties of metallic/ceramic composites made of the mixture of powders: austenitic steel (316LHD) and ceramics (Al2O3).

Abstract:

Monolithic ceramic materials have been used in industry for hundreds of years. These materials have proven their usefulness in many applications, yet, their potential for critical structural applications is limited. The existence of an imperfection in a monolithic ceramic on the order of several microns in size may be critical, resulting in catastrophic failure. To overcome this extreme sensitivity to sman material imperfections, reinforced ceramic materials have been developed. A ceramic matrix which has been reinforced with continuous fibers is not only less sensitive to microscopic flaws, but is also able to sustain significant damage without suffering catastrophic failure.

A borosilicate glass reinforced with several layers of plain weave silicon carbide cloth (Nicalon) has been studied. The mechanical testing which was performed included both flexural and tensile loading configurations. This testing was done not only to determine the material properties, but also to initiate a controlled amount of damage within each specimen.

Several nondestructive testing techniques, including acousto-ultrasonics (AU), were performed on the specimens periodically during testing. The AU signals were monitored through the use of an IBM compatible personal computer with a high speed data acquisition board. Software has been written which manipulates the AU signals in both the time and frequency domains, resulting in quantitative measures of the mechanical response of the material.

This paper will compare the measured AU parameters to both the mechanical test results and data from other nondestructive methods including ultrasonic C-scans and penetrant enhanced X-ray radiography.

Com o desenvolvimento da tecnologia sem fio, muitos dispositivos eletrÃnicos exigem alta integraÃÃo e que possuam propriedades multifuncionais. Em tal caso, compÃsitos magneto-dielÃtricos tÃm atraÃdo muita atenÃÃo devido as suas propriedades. Nesse sentido, a pesquisa sobre compÃsitos à empregada para a busca de novos materiais. O titanato de cÃlcio (CaTiO3 - CTO) e a granada de Ãtrio e ferro (Y3Fe5O12 - YIG) possuem excelentes propriedades dielÃtricas e ferrimagnÃticas, respectivamente. Este trabalho apresenta a obtenÃÃo do compÃsito ferrimagnÃtico, constituÃdo pelas fases YIG e CTO, atravÃs da rota sintÃtica no estado sÃlido com a utilizaÃÃo de moagem mecÃnica de alta energia. As fases das cerÃmicas foram sinterizadas a 1200ÂC/5h. A DifraÃÃo de Raios-X, a Espectroscopia Raman e MÃssbauer foram essenciais para caracterizaÃÃo estrutural dos compÃsitos. A morfologia das amostras foi elucidada pela Microscopia EletrÃnica de Varredura e auxiliada pela Picnometria a fim de avaliar a densificaÃÃo do material. Adicionalmente, foram realizados experimentos para se avaliar o comportamento elÃtrico e magnÃtico dos compÃsitos na faixa de radiofrequÃncia e de micro-ondas, para depois sugerir uma aplicaÃÃo tecnolÃgica cabÃvel. Os resultados obtidos pela DifraÃÃo de Raio X e da Espectroscopia Raman confirmaram que a sÃntese das fases foi realizada de forma satisfatÃria. As anÃlises qualitativas dos espectros MÃssbauer mostraram boa concordÃncia com os resultados apresentados pela DifraÃÃo de raios-x. Os compÃsitos apresentaram permissividade dielÃtrica praticamente constante na faixa de 50 MHz a 1,5 GHz. Ao analisar o aumento e a diminuiÃÃo da concentraÃÃo em massa de CTO e YIG, respectivamente, foi percebido que os valores de εr aumentaram. A partir dos valores obtidos, pode-se sugerir que o compÃsito sintetizado possui potencial para ser utilizado em dispositivos de micro-ondas, tais como para antenas monopolo.
With the development of wireless technology, many electronic devices require high integration and materials with multifunctional properties. In such a case, magneto-dielectric composites have attracted much attention because they have both magnetic and dielectric properties. In this sense, research on composites is employed to search for new materials. The calcium titanate and yttrium iron garnet possess excellent dielectric properties and ferrimagnetic, respectively. This paper presents the preparation of ferrimagnetic composite, comprising the steps Y3Fe5O12 (YIG) and CaTiO3 (CTO) by the solid state synthetic route with the use of high energy mechanical grinding. The phases of the ceramics were sintered at 1200 Â C for 5 h. The X-ray diffraction, Raman and MÃssbauer Spectroscopy were used to elucidade structural properties of the composites. The morphological characteristics of the samples were elucidated by Scanning Electron Microscopy and supported by Pycnometry to analyze the densification of the material. Furthermore, experiments to evaluate the electrical and magnetic behavior of composites in the range of radiofrequency and microwave were performed and finally an appropriate technological application was suggested. The results obtained by X-Ray Diffraction and Raman spectroscopy confirm that the synthesis of YIG was successfully obtained. The structural characterization of pure and composite samples was performed successfully and the formation of ionic phase in composites YIG-CTO was found, being in the same family of oxide in which the CTO is inserted. Qualitative analysis of the MÃssbauer spectra showed good agreement with the results reported by x-ray diffraction. The dielectric permittivity composites showed almost constant in the range of 50 MHz to 1.5 GHz. Evaluating the increasing and decreasing in mass concentration of CTO and YIG, respectively and it was realized that the values of εr increased. Two profiles was noticed in the compositional series, it can be inferred that the possibility of the reaction of YIG and CTO products may be interfering with the proper measurements.

Abstract:
Matrix damage and its effects on mechanical properties have been examined for SiC (Nicalon1) fibre reinforced glass and glass ceramic matrix composites under quasi-static and fatigue loading conditions. Nicalon/Pyrex laminates of different lay-ups have been tested under quasi-static tension. The elastic moduli have been measured and matrix damage monitored as a function of applied strain. The mechanical properties are strongly influenced by the presence of crystalline regions in the matrix which promote microcracking. Laminated plate theory is used to provide bounds to the moduli of the laminates. For unidirectional and simple crossply Nicalon/CAS2 laminates the quasi-static stress/strain behaviour and associated matrix damage accumulation have been examined in detail. The damage development with applied stress was quantified by counts of crack density (in both longitudinal and transverse plies), stiffness loss and cumulative residual strain. The quasi static stress/strain behaviour during continuous tests (accumulating damage) and discontinuous tests (constant damage) have been modelled using a stress analysis based on Aveston, Cooper and Kelly (ACK) theory. The continuous stress/strain behaviour of (0/90) crossply laminates has been modelled using a shear-lag analysis developed previously to describe the transverse ply cracking behaviour of polymer matrix composites. The analysis is modified to account for longitudinal ply cracking. Matrix damage development in unidirectional and (0/90) crossply laminates under quasistatic cycling and high frequency fatigue loading have been studied. For unidirectional laminates stable stress/strain hysteresis loops were obtained during quasi-static cycling, corresponding to stable matrix damage states. These and similar loops obtained after high frequency fatigue are modelled using, the discontinuous stress/strain analysis. It is suggested that the effect of high frequency fatigue is to decrease the interfacial shear strength.

La synthèse hydrothermale a permis de synthétiser des poudres nanométriques de zircone stabilisée à l'oxyde d'yttrium, d'alumine (boehmite) et d'alumine-zircone. La caractérisation physique (diffraction des rayons x, densité, surface spécifique, analyse thermique différentielle, microscopie électronique. . . ) de ces poudres obtenues pour plusieurs températures de traitement hydrothermal a été réalisée. Les paramètres de cogélification des précurseurs de nitrates de zirconyle et d'aluminium par de la potasse ont été optimisés pour obtenir des poudres composites homogènes a l'échelle micronique. La taille de la poudre de zircone varie entre 13 et 25 nanomètres. La boehmite et l'alumine gamma présentent la même répartition granulométrique comprise entre 30 et 70 nanomètres. Le frittage naturel de ces poudres composites est devenu possible grâce à l'ensemencement du gel par de l'alumine alpha fine. Le comportement au frittage sous charge, la caractérisation des propriétés mécaniques (résistance à la flexion, facteur critique d'intensité de contrainte et dureté) et des microstructures ont été étudiés. Les microstructures obtenues sont nanométriques et présentent une répartition homogène entre les deux phases. La zircone présente est sous forme quadratique non transformable les nanocomposites étudiés à 5 et 50 % en volume de zircone présentent des valeurs de facteur critique d'intensité de contrainte améliorées par rapport à l'alumine pure. La résistance à la flexion pour la composition à 5 % de zircone est comparable par rapport à une alumine fine. Par contre nous observons une diminution de cette résistance à la flexion pour le nanocomposite à 50 % de zircone en raison d'un ensemencement insuffisant. Un essai de thermocompression a permis de réaliser des jonctions parfaites sans aucune aspérité et avec une excellente continuité au niveau des interfaces de nos nanocomposites alumine-zircone, ce qui laisse a priori suggérer un bon comportement superplastique.

L'objectif de cette étude était de développer un protocole de fabrication de nanocomposites à matrice d'alumine renforcée par des particules nanométriques (< 200 nm) de carbure de silicium utilisant des poudres commerciales et l'eau comme milieu de dispersion, ceci dans un but de faisabilité industrielle. Après la détermination des meilleures conditions de dispersion des poudres d'alumine et de carbure de silicium choisies, les mélanges ont été densifies par pressage à chaud afin d'obtenir des matériaux complètement denses. Malgré la température de frittage plus élevée utilisée pour les nanocomposites (1550°C au lieu de 1400°C), la taille moyenne des grains d'alumine se situant entre 0. 6 et 1. 5 µm est équivalente ou inférieure à celle des grains du matériau monolithique. L'étude des propriétés mécaniques a température ambiante de nanocomposites contenant entre 2. 5 et 25% en volume de SiC a permis de déterminer l'influence de la teneur en dispersoïdes à savoir une augmentation de la résistance en flexion (une valeur de 1 GPA a été obtenue pour le nanocomposite contentant 7. 5% en volume de SiC), une amélioration assez modeste de la ténacité, une légère diminution du module de Young ainsi qu'une faible augmentation de la dureté. L’étude comparative de la résistance au fluage de l'alumine et d'un nanocomposite contenant 5% en volume de SiC a montré que la vitesse de déformation du nanocomposite est 100 fois plus faible que celle de l'alumine pure. Un modèle de blocage du glissement aux joints de grains par les particules de SiC est proposé.

Abstract:
This study was intended to investigate the mechanical properties and microstructure of iron based composite reinforced by ultra high temperature ceramics fabricated by powder metallurgy technique. The fabrication parameters were optimized and composite samples with different volume fraction of TiB2 were fabricated and were subjected to different mechanical tests. The results indicated improving in mechanical properties of Fe-TiB2 composites by increasing the volume fraction of TiB2 up to 20 vol%. More TiB2 particles didn?t improve the mechanical properties of composite, instead adversely affected it due to increasing the chance of agglomeration and porosity in entire microstructure. Another finding showed the twofold characteristic of TiB2 on mechanical properties of composite via increasing the hardness and decreasing the bulk density of composite. Finite Element Analysis (FEA) have also been performed on microstructural based developed models to simulate failure of composites. Numerical simulation results could verify the experimental results.

Abstract:
Monolithic ceramics and continuous fiber reinforced ceramic composites are being developed for use in high temperature applications such as combustor liners in gas turbines, thrust deflectors for jet engines, and thruster nozzles. Ceramic composite materials possess the high temperature resistance properties of ceramics, but have better creep and cyclic properties. However, the properties of these materials change somewhat with time at service temperatures, i.e., their material state changes as a function of service conditions and history. The authors have developed a methodology for representing and combining the effects of high temperature material state changes in CMCs, along with changes in applied stress / strain conditions during service, to estimate remaining strength and life of ceramic composite materials and components. Fatigue, creep rupture, and time dependent deformation are combined by a strength metric in integral form to create a time-resolved, point-wise estimate of current remaining strength and life in material elements. Application of this methodology in discrete element representations of mechanical behavior of structural elements with nonuniform stress / strain states has been implemented.

Abstract:
Conventional sintered silicon carbide (SSiC) has been applied in journal bearings of pumps for more than 20 years with the pumped medium itself being the lubricant. High corrosion and wear resistance of SSiC have contributed to this success. The brittle failure of that material quite often is a problem, though, and limits the application of SSiC in highly loaded bearings. In contrast, ceramic matrix composites (CMC) based on C- or SiC-fiber-reinforced SiC-ceramics show strongly improved fracture toughness on the level of cast iron and are applicable in cases where conventional ceramics due to their lack of reliability cannot be used. These CMC-materials have been developed in several programs primarily for space and military applications and are also beeing successfully used in journal bearings for pumps in power plants [1] and for tubular casing pumps [2]. In power plant pumps, low viscosity water of up to 160°C can be the lubricant. In tubular casing pumps quite often water loaded with abrasive sand particles lubricates the bearings. CMC-journal bearings for pumps in cryogenic rocket engines for reusable launch vehicles (RLVs), where the lifetime of mechanical components is a critical issue, are presently tested. Journal bearings of the type introduced in water pumps could replace ball bearings presently in use. Improved stiffness and damping properties, reduced wear, increased reliability and no limitations in speed times diameter would be some of the expected advantages [3]. Journal bearings for hot hinges in re-entry systems are foreseen for the space vehicle CRV (crew rescue vehicle) and have successfully been tested under close to real conditions. They are envisaged to be flight-tested on the experimental NASA vehicle X38. The bearing faces run under dry conditions and temperatures of more than 1600°C in air of about 50 mbar pressure [4]. Presently, only CMCs based on carbon fibers have potential to operate successfully under such conditions.

Abstract:
The NASA High Speed Research (HSR)/Enabling Propulsion Materials (EPM) program was charged with the responsibility for developing the materials and technologies necessary to meet the High Speed Civil Transport (HSCT) engine requirements. The combustor liner was identified as a critical component for meeting the efficiency and environmental acceptability goals of the HSCT engine. The EPM Ceramic Matrix Composite (CMC) Combustor liner program was tasked with developing and demonstrating a material system and design concept that meets the HSCT environmental, thermal, structural, economic, and durability requirements. Melt Infiltration (MI) SiC/SiC composites were ultimately selected for the combustor liner application. The culmination of this development effort was the delivery and testing of a CMC combustor liner. Testing was performed at NASA Glenn Research Center in the Sector Rig under HSCT operating conditions. The initial results of the rig testing are presented.

Abstract:
Strong, tough, high temperature ceramic matrix composites are currently being developed for application in advanced heat engines. One of the most promising of these new materials is a SiC fiber-reinforced silicon nitride ceramic matrix composite (SiCf/Si3N4). The interfacial shear strength in such composites is dependant on the integrity of the fiber’s carbon coating at the fiber-matrix interface. The integrity of the carbon rich interface can be significantly reduced if the carbon is oxidized. Since the thermal diffusivity of the fiber is greater than that of the matrix material, the removal of carbon increases the contact resistance at the interface reducing the thermal diffusivity of the composite. Therefore thermal diffusivity images can be used to characterize the progression of carbon depletion and degradation of the composite. A new thermal imaging technique has been developed to provide rapid large area measurements of the thermal diffusivity perpendicular to the fiber direction in these composites. Results of diffusivity measurements will be presented for a series of SiCf/Si3N4 (reaction bonded silicon nitride) composite samples heat-treated under various conditions. Additionally, the ability of this technique to characterize damage in both ceramic and other high temperature composites will be shown.

Abstract:
Advanced materials are a key element in the development of modern aerospace vehicles and composites are one of the most promising types of such materials. They tend to be significantly lighter than their metal counterparts, while possessing impressive strength and performance characteristics. This paper describes recent work and developments in three major types of composite materials — polymer matrix composite (PMC), metal matrix composite (MMC), and ceramic matrix composite (CMC). Recent work in nanocomposites, which is particularly applicable to polymer matrix and metal matrix composites is also presented and discussed. In addition, some recent work in composite material damping is discussed and a modeling strategy for amplitude dependent damping is developing based upon heuristic modeling considerations and experimental testing results.

Abstract:
A macroscopic noninteractive reliability model for ceramic matrix composites is presented. The model is multiaxial and applicable to composites that can be characterized as orthotropic. Tensorial invariant theory is used to create an integrity basis with invariants that correspond to physical mechanisms related to fracture. This integrity basis is then used to construct a failure function per unit volume (or area) of material. It is assumed that the overall strength of the composite is governed by weakest link theory. This leads to a Weibull type model similar in nature to the principle of independent action (PIA) model for isotropic monolithic ceramics. An experimental program to obtain model parameters is briefly discussed. In addition, qualitative features of the model are illustrated by presenting reliability surfaces for various model parameters.

Abstract:
The improvement of bulk ceramic properties through the addition of a secondary or even tertiary phase is a field of research that has been actively pursued since the mid twentieth century. This pursuit has become more relavent with the adoption of ceramic phases to protect structural components within the hotpath of gas turbines. Improving the properties of these ceramic coatings and tiles has the potential of reducing catastrophic damage events leading to an overall reduction in unplanned maintence and downtime. To date, Several approaches have been undertaken to improve the physical properties of these ceramics including preferential microstructural grain growth and doping to develop metastable crystal phases. This paper examines the effect of whisker additions to a mechanical mixture of oxide ceramics on the erosion properties. The baseline structure is a mechanical mixture of zirconia and alumina particles in the ratio of 89.8vol% alumina to 10.2vol% partially stabalized zirconia. A ratio of 20.0vol% mullite whiskers is incorporated into the structure as a toughening agent. The mullite whiskers are grown using a molten salt method. The overall structural composition is 20.0vol% mullite whiskers, 8.2vol% partially stabilized zirconia, and 71.8vol% alumina. This whisker toughened material is compared to a baseline 89.8vol% alumina 10.2vol% zirconia ceramic. Erosion tests were conducted using a 50 μm diameter alumina erodant with a velocity of 104 m/s. Impingement angles of 30°, 60° and 90° were examined to determine the effect of whisker additions at steeper attack angles. Despite the increased hardness, tensile strength and fracture toughness, whisker-enhanced zirconia-toughened alumina has shown similar erosion rate as non-reinforced ZTA at 30° ad 90° and much higher erostion at 60°. It can be surmised that whisker-enhanced toughening of ceramics has little positive effect on the erosion resistance of ceramics at room temperature and is potentially harmful. Microstructure analysis results are also presented within to illustrate the erosion material removal mode under different conditions.
