Abstract:
3D printing is one of the emerging technologies in the manufacturing sector, and polymer materials play a vital role in the raw material of the additive manufacturing sector. This research explores reducing the production time by testing and analyzing the microstructure of the different polylactic acid (PLA) filament polymer samples. For this purpose, 15 pieces of ASTM (American society for testing and materials) D638 tensile samples with polylactic acid (PLA) filaments have been used exclusively with five different sets of modified process parameters in slicing software of 3D printing technology. The results of this research reveal the best PLA filament FDM production method in terms of time, mechanical strength, and FESEM analysis comparing all the results.

Abstract:
The main objective of this research study is to optimize the printing parameters that can be used in the FDM (fusion deposition modeling) production method to obtain the lowest production time and best printing parameter of PLA (polylactic acid) filament with the tensile test. The printing parameter that can be used in FDM machines such as extruder temperature, bed temperature, layer height, printing speed, travel speed, infill, and shell count is taken into account for optimization. In addition, the tensile specimens from ASTM (American Society for Testing and Materials) D638 standard were manufactured by PLA filament with the above-modified printing parameters. The best printing parameters for PLA products were found by the time recorded during production and tensile test results after production. Thus, through this research, one can find the best PLA filament printing parameters and their timing.

Abstract:
AbstractIn the recent years, additive manufacturing became an interesting topic in many fields due to the ease of manufacturing complex objects. However, it is impossible to determine the mechanical properties of any additive manufacturing parts without testing them. In this work, the mechanical properties with focus on ultimate tensile strength and modulus of elasticity of 3D printed acrylonitrile butadi-ene styrene (ABS) specimens were investigated. The tensile tests were carried using Zwick Z005 loading machine with a capacity of 5KN according to the American Society for Testing and Materials (ASTM) D638 standard test methods for tensile properties of plastics. The aim of this study is to investigate the influence of printing direction on the mechanical properties of the printed specimens. Thus, for each printing direction ( and ), five specimens were printed. Tensile testing of the 3D printed ABS specimens showed that the printing direction made the strongest specimen at an ultimate tensile strength of 22 MPa while at printing direction it showed 12 MPa. No influence on the modulus of elasticity was noticed. The experimental results are presented in the manuscript.

Abstract:
Purpose – The purpose of this study is to investigate the influences of the supports on tensile strength (TS) of stereolithography (SL) parts. Design/methodology/approach – The shape of specimens (tensile specimens) is according to the American Society Testing and Materials (ASTM) D638 standard. Some parts have support trace on one side and some have support trace on both sides. To achieve this target, some parts are fabricated on other parts; therefore, support of the upper part is fabricated on upper face of lower part. Findings – Influences of supports traces on mechanical properties aren’t “zero”. Supports affect TS of SL parts by affecting surface roughness of parts. After experimentation and analyzing experimental results, it is concluded that the TS of the parts which have support on both sides is slightly lower than the parts which have support just on one side. Originality/value – This is the first attempt toward investigation of supports effects on the mechanical properties in SL parts.

Abstract:
A successful attempt has been made to develop coir fibre composites reinforced with graphene, epoxy and carbon fibre. The carbon fibres were arranged in an intercalated manner, which is similar to the coir fibres. The percentage composition of graphene was varied as 1, 2, 4 and 6% by weight of the holding matrix. Suitable surface modifications were done by treating natural fibres by 5% NaOH and 0.3% KMnO4 for better adhesion of fibre and epoxy resin. Sonication and cetyl trimethyl ammonium bromide treatments were also done to achieve the fine scattering of graphene in the epoxy matrix in order to achieve better mechanical behaviour. Moulds were made as per D638 American Society for Testing and Materials (ASTM) standards. The treated fibres were then arranged in the mould by the conventional hand layup technique. Tensile testing was carried out to determine the mechanical properties of the composites. Two-way analysis of variance was used as a statistical tool to find the effect of parameters such as ‘Percentage composition of graphene’ and ‘Type of mould’ on the modulus of the composites. Fourier transform infrared spectroscopy was conducted to determine the interferential adhesion and homogeneous distribution of fibres in the composite matrix. At last, field emission scanning electron microscopy analyses were also done to the specimens before and after tensile testing to determine the morphology of different entities present in the composites.

Abstract:
There is limited knowledge about energy and carbon emission performance comparison between additive fused deposition modeling (FDM) and consolidation plastic injection molding (PIM) forming techniques, despite their recent high industrial applications such as tools and fixtures. In this study, developed empirical models focus on the production phase of the polylactic acid (PLA) thermoplastic polyester life cycle while using FDM and PIM processes to produce American Society for Testing and Materials (ASTM) D638 Type IV dog bone samples to compare their energy consumption and eco-impact. It was established that energy consumption by the FDM layer creation phase dominated the filament extrusion and PLA pellet production phases, with, overwhelmingly, 99% of the total energy consumption in the three production phases combined. During FDM PLA production, about 95.5% of energy consumption was seen during actual FDM part building. This means that the FDM process parameters such as infill percentage, layer thickness, and printing speed can be optimized to significantly improve the energy consumption of the FDM process. Furthermore, plastic injection molding consumed about 38.2% less energy and produced less carbon emissions per one kilogram of PLA formed parts compared to the FDM process. The developed functional unit measurement models can be employed in setting sustainable manufacturing goals for PLA production.

Abstract:
This research was conducted to evaluate the strength and folding performance of polypropylene packaging samples, when exposed to hot air and high humidity condition. Three types of polypropylene samples were chosen, which were flat plastic, plastic with hinges, and plastic film. All of these samples were tested for tensile strength; except plastic with hinges that received additional test to evaluate the folding endurance. American Society for Testing and Materials (ASTM) D638 standard was applied to analyze the mechanical strength of these plastics. This standard was used to determine the value of stress, strain, and Young’s modulus. Each sample was exposed to different temperature settings, which were 20°C, 25°C, and 30°C for high humidity condition and 60°C, 65°C, and 70°C for hot air condition. As for the folding endurance test, the hot air temperatures were selected at 60°C, 65°C and 70°C and for the high humidity condition, the range of relative humidity were set at 50%, 55% and 60%. Based on the tensile test results, the values of stress and Young’s modulus were higher at higher humidity as compared with the values under hot air condition. However the strain value was the opposite of the stress and Young’s modulus, whereby the values started to deceive under high humidity condition, but kept on increasing under hot air condition. In folding endurance test, it was confirmed that the hinge performed better under hot air environment than high humidity. As the relative humidity increases, the average number of folding decreased from 3.00x106 to 2.89x106 cycles. In the other hand, thevalue of folding numbers increased from 3.34x106 to 3.37x106, with increasing temperature. In conclusion, through this performance analysis, the outcomes can be applied to other packaging materials and appliances, which are related to high temperature and high humidity condition.

Abstract:
Dust particles in the atmosphere are a key cause of nuisance, health and other environmental problems. The mining sector is a major source of airborne particulate matter caused by operations like terrain clearing, drilling, blasting, tipping and loading and the passage of vehicles on unpaved roads. The nuisance effect of airborne dust can be measured by using dust buckets and/or directional dust deposition gauges. Dust buckets are used to determine vertical dust deposition rates and directional dust deposition gauges are used to determine the direction of the sources. Traditionally the measurement of the vertical flux of dust, or dust deposition has been used as to indicate the nuisance caused by coarse suspended particulate matter. Several countries have produced standards for permissible dust deposition rates. Although alternative deposition measurement methods have been proposed, ASTM D1739 has remained the method most often used in the South African mining and industrial sectors to measure dust deposition. In addition, a number of non-standard directional dust deposition gauges have been used. SANS 1929:2005 (South African National Standards, 2005) prescribes the use of ASTM D1739:98 for measuring dust deposition. However, for historical reasons the previous version, ASTM D1739:70 (re-approved as ASTM D1739:82) is still widely used and in the recently promulgated South African Dust Management regulations the use of this version is prescribed. In order to determine the difference in the results obtained by the two versions, ASTM D1739:82 and ASTM D1739:98 were used to measure dust deposition levels arising from a coal mining operation in the Mpumalanga Province and a gold mining operation in North-West Province. In order to determine whether a correlation exists between vertical dust flux (dust deposition) and horizontal dust flux, standard directional horizontal dust flux gauges according to BS 1747 part 5 were also set up at both sites. The measurement of dust deposition using three dust deposition gauges (i.e. ASTM D1739:82, ASTM D1739:98 and BS 1747 part 5, directional dust deposition gauges) was undertaken monthly over a period of fourteen (14) months at the two sites. The findings of the study indicate that the dust deposition rates for an opencast coal mine are generally higher than the dust deposition rates for an underground gold mine. ASTM D1739:98 was shown to be a more efficient dust deposition collection method than ASTM D1739:82, with the ratio between the mean values slightly more than 2. The addition of water to the dust bucket does not make a statistically significant difference to retention of dust in the bucket. There is a weak correlation between results for the vertical dust gauges and horizontal dust flux. It is recommended that the South African mining sector continue dust deposition monitoring and reporting using the more recent version of ASTM D1739, as high deposition levels may indicate a potential health impact from PM10 thoracic dust.

Abstract:
Delamination propagation in laminated composite materials is a common issue that always concerns us when we consider composites for structural purpose. Many possible solutions have been studied; the most famous is the three-dimensional (3D) woven composites materials, which have promising interlaminar fracture resistance but at the cost of increasing density, which for aerospace industry is very important. In this chapter, mode 1 double cantilever beam (DCB) interlaminar fracture toughness tests according to the American Society for Testing and Materials (ASTM) D5528 standard were performed on composite specimens made of E-Glass Saertex 830 g/m2 Biaxial (+/−45°) with Sypol 8086 CCP polyester resin with orthogonal z-axis oriented yarn woven of 0.22 mm diameter nylon monofilament. Four specimens were made with a longitudinal distance between the warp binders of 0.5, 1, 1.5, and 2 cm, respectively. A tensile test according to the ASTM D3039 standard was performed to study how z-binder may affect tensile resistance. The results show a considerable increase in interlaminar fracture toughness, several stress concentrators have been created because of the new yarn and premature failure in the matrix.

Full text
Abstract:
Thailand is an agriculture-based country with the potential to cultivate a vast array of plant species, including castor. Castor oil is produced by pressing castor seeds. Castor oil was selected as the preferred vegetable oil for biodiesel production. Castor oil is primarily composed of ricinoleic acid, a hydroxyl fatty acid. Response surface methodology was used in this study to optimize the biodiesel production process parameters. This study varies the molar ratio of methanol to oil, the concentration of the catalyst, the reaction temperature, and the reaction time. As a catalyst, potassium hydroxide was used in the transesterification process. In this study, response surface methodology is utilized in conjunction with central composite design (CCD) experiment design. Therefore, the optimal yield of castor oil transesterification is 4.02 methanol to 1 oil, a catalyst concentration of 0.90%, a reaction temperature of 49.87 ∘C, and a reaction time of 59.21 minutes. These optimal conditions resulted in a %fatty acid methyl ester (FAME) yield of castor oil biodiesel of 88.25 %, which is within 5% of the predicted %FAME yield. Transesterification under optimal conditions demonstrates that the physiochemical properties of castor oil biodiesel are enhanced. The viscosity of castor oil is approximately 235 cSt at 40 ∘C. After transesterification, the viscosity of castor oil decreases to 15.2 cSt at 40 ∘C under optimal conditions. The density and flash point of castor oil biodiesel is 0.92 g/cm3 and 196 ∘C, respectively. It discovers that the flash point of castor-oil biodiesel complies with the American Society for Testing and Materials (ASTM) standard, whereas its viscosity and density do not. However, castor oil biodiesel can be blended with diesel petroleum to reduce its viscosity and meet ASTM specifications.

Abstract:
Many aspects of a chemical analysis must be scrutinized to ensure that the product, a report containing the results of the analysis, fulfills the expectations of the client. One of the more fundamental factors is the analytical method itself. How was it chosen? Where does it come from? When a laboratory is faced with a problem requiring chemical analysis, there may be set methods described in a standard operating procedure, but often the analyst might have to make a choice among methods. For the majority of analytical methods used in field laboratories, there is neither the expertise nor the inclination to start from scratch and reinvent the wheel. The analyst wants a method that can be implemented in his or her laboratory. Compilations of methods that have been evaluated do exist and have the imprimatur of international organizations such as the International Organization for Standardization (ISO) or the American Society for Testing and Materials (ASTM). Failing this, the scientific literature abounds in potential methods that have the recommendation of the authors, but may not always be as suitable as claimed. This chapter has two aims: to demonstrate the necessity of using properly validated and verified methods and to explain what constitutes a validated method, and to provide an introduction to method validation for in-house methods. There is an abundance of published material that defines, describes, and generally assists with method validation, some of which is referenced here (Burgess 2000; Christensen et al. 1995; EURACHEM 1998; Fajgelj and Ambrus 2000; Green 1996; Hibbert 2005; ICH 1995, 1996; LGC 2003; Thompson et al. 2002; USP 1999; Wood 1999). “Method validation” is a term used for the suite of procedures to which an analytical method is subjected to provide objective evidence that the method, if used in the manner specified, will produce results that conform to the statement of the method validation parameters. Like many aspects quality assurance, method validation is of a relative nature. As with the concept of fitness for purpose, a method is validated for a particular use under particular circumstances. If those circumstances vary, then the method would need to be re-validated at least for the differences.

Abstract:
Biodiesel mainly comes from edible oil, and there is little research on its yield from non-edible sources with low-cost oil. It is paramount to investigate the non-edible oil resources which may lead to advance the commercial feasibility of biodiesel and cost effectiveness as well as resolve the food issues. This chapter describes four novel non-edible seed oil sources comprising Koelreuteria paniculata, Rhus typhina, Acacia farnesiana and Albizzia julibrissin for biodiesel production. We aimed to optimize different reaction parameters for oil extraction, alkali-catalyzed transesterification process for maximal biodiesel production and finally evaluate its compatibility with mineral diesel. The optimization factors in transesterification included the molar ratio of methanol to oil, reaction time, stirring intensity, catalyst concentration and temperature. Two methods have been described including Soxhlet and mechanical for extraction of seed oil. The synthesized esters were evaluated and characterized through the nuclear magnetic resonance (NMR; 1H and 13C), Fourier transform infrared (FT-IR) and gas chromatography–mass spectrometry (GC–MS) and the total conversion of crude oil to fatty acid methyl esters (FAMEs) were established. The inductively coupled plasma-optical emission spectrometry (ICP-OES) and Elemental Analyzer (EA) were used for evaluation of elemental concentration. The physico-chemical characterizations of the biodiesel, i.e., flash point, pour point, cloud point, and density were within the American Society for Testing and Materials (ASTM; D6751) and European Standards ((EN14214). Koelreuteria paniculata produced highest biodiesel oil content by Soxhlet extraction (28–30%) followed by the Albizzia julibrissin (19–24%), Acacia farnesiana (23%), Rhus typhina (20–22%). The density ranged from 0.83–0.87 @ 15°C (g/cm3) and the kinematic viscosity ranged from 3.75–6.3 (mm2/s) among all the plant sources. Koelreuteria paniculata had highest Na (5456.2), Cr (1246.8), Ni (658.36), and Al (346.87) elemental concentrations (μg/g) than other plant sources. The elemental percent of C, H, N, and O of biodiesel ranged from 72.54–76.86, 11.25–13.34, 1.97–2.73, and 9.86–12, respectively. In conclusion, these non-edible plant seeds offer a cheap source of renewable energy and can be easily grown on barren and wastelands and contribute to efficient biodiesel production to mitigate the energy crisis.

Abstract:
Small punch test specimens are widely used for a long time as they are simple to produce and requires only a small volume of material. This fact is advantageous especially for high activity materials but also for assessment of operational damage in components materials when component integrity and strength may not be affected. In the same time, no test standard exists and several different specimen types and test procedures have been developed in different place. Thus, to unify this activity, considerable attention has been paid since 2012 to the standardization of small punch test technique within the American Society of Testing and Materials (ASTM). In 2016 a large InterLaboratory Study has been launched within the ASTM subcommittee E10.02 - Behavior and Use of Nuclear Structural Materials, involving 12 laboratories and 6 evaluated structural materials from the nuclear and non-nuclear power plant components. Paper describes the current status of ASTM standardization, results of the InterLaboratory Study, first analysis of the results with respect to some important test parameters, lessons learned and open questions remaining to be solved for the successful completion of the standardization process.

Abstract:
Development of an updated single filament test standard for tensile strength determination has been undertaken by a joint government-industry task group under the auspices of the Subcommittee C28.07 of the American Society for Testing and Materials (ASTM). This update was initiated in response to a need expressed by people involved with fiber testing. A fiber testing workshop in 1991 attracted a wide range of attendees with concerns regarding the uniformity of testing methods and comparability of resulting data in the fiber literature. With the inception of a C28.07.07 Task Group for Ceramic Fibers, an effort to conduct round robin testing was begun among interested government and industrial test facilities. User surveys and discussion groups were also employed to determine areas of concern with the current standard test method, ASTM D 3379-75. Shortcomings in the current standard were identified and methods of addressing these areas were discussed with experts including fiber manufacturers, testing facilities and composite manufacturers. Among the main concerns was the method and application of fiber diameter measurements.

Full text
Abstract:
Elastic-plastic crack front fields in arc-shaped tension specimens (C-specimens) were analyzed by a three-dimensional finite element method. The effect of side grooves on the ductile fracture behavior was investigated by studying the J-integral distribution, plane-strain constraint parameter, and development of plastic zones and comparing to experimental data. The applicability of the η factor (derived for use with compact tension specimens) for the calculation of J-integral values for the C-specimen was also investigated. The results show that side grooves promote and establish near plane strain conditions at the crack front in sub-size specimens. It was also found that a two-dimensional plane-strain analysis in conjunction with the standard American Society for Testing and Materials (ASTM) tests was sufficient to determine the fracture toughness values from side-grooved C-specimen. The results indicate the η factor for compact tension specimen as specified in the ASTM standards appears to produce reliable results for the calculation of J of C-specimens.

Abstract:
An update is presented of the activities of the American Society for Testing and Materials (ASTM) Committee C-28 on Advanced Ceramics. Since its inception in 1986, this committee, which has five standard producing subcommittees, has written and published over 32 consensus standards. These standards are concerned with mechanical testing of monolithic and composite ceramics, nondestructive examination, statistical analysis and design, powder characterization, quantitative microscopy, fractography, and terminology. These standards ensure optimum material behavior with physical and mechanical property reproducibility, component reliability, and well-defined methods of data treatment and material analysis for both monolithic and composite materials. Committee C-28 continues to sponsor technical symposia and to cooperate in the development of international standards. An update of recent and current activities as well as possible new areas of standardization work will be presented.

Abstract:
The master curve approach was utilized to compare fracture toughness of American Society for Testing of Materials (ASTM) A285 as developed from Charpy v-notch (CVN) data and predictive statistical models. The master curves for each of the data sets were developed in accordance with American Society for Testing Materials Specification E 1921 (ASTM E1921, “Standard Test Method for Determination of Reference Temperature, T0, for Ferritic Steels in the Transition Range”), as prescribed by American Petroleum Institute Recommended Practice 579 (API-579, “Fitness for Service”). The results indicate that predictive statistical models developed from compact tension test results express a lower fracture toughness distribution when compared to CVN data.

Abstract:
In 1982, the American Society for Testing and Materials (ASTM) adopted consensus standard direct-normal and global-tilted solar terrestrial spectra (ASTM E891/E892). These standard spectra were intended to evaluate photovoltaic (PV) device performance and other solar-related applications. The International Standards Organization (ISO) and International Electrotechnical Commission (IEC) adopted these spectra as spectral standards ISO 9845-1 and IEC 60904-3. Additional information and more accurately representative spectra are needed by today’s PV community. Modern terrestrial spectral radiation models, knowledge of atmospheric physics, and measured radiometric quantities are applied to develop new reference spectra for consideration by ASTM.

Full text
Abstract:
The focus of this study is to investigate how to lightweight SMC composites for automotive applications without compromising their performance. This is accomplished by replacing, at least partially, the heaviest materials such as the glass fibers (GF) or calcium carbonate (CaCO3) with nanocellulose or nanoclays. In addition, the chopped glass fibers are replaced by glass fabric in order to better control the location and orientation of the glass fiber reinforcement and thus engineer the mechanical properties. Unsaturated polyester resin (UPR) is used as the resin, and a pilot scale sheet molding compounds (SMC) is used to make the SMC. The composites are made by stacking plies of SMC layers in a mold, after appropriate conditioning of the SMC, and compression molding. The properties of interest are the tensile and flexural modulus and strength according to the corresponding ASTM standards and the density of the composites. The void content is also determined using acid digestion and scanning electron microscopy. The main goal is to replace traditional chopped glass fibers (GF) used in SMC with unidirectional glass fabric coated with cellulose nanocrystals (CNC). The reasoning is to enhance properties with a better UPR/GF interface and controlled fiber orientation while reducing density. The glass fiber fabric is coated with nanocellulose using a scalable spraying technique that leads to homogeneous coatings. The four different glass fiber fabrics that were used in this study vary in CNC coating amount. To understand the effect of the nanocellulose, the glass fiber content of all composite formulations was kept constant at about 30 vol%. In addition, to determine the mechanical properties of the composites, the viscosity was verified for all formulations to ensure processability using the SMC pilot line. SEM micrographs show the quality of the CNC coating on the glass fiber fabric. Water uptake of all composites was also determined. The expected results address design, processing, and testing challenges, and successes and failures. The question to be addressed is whether CNC coated fabric is significantly advantageous for SMC compared to randomly oriented, chopped GF.

Abstract:
The need for advanced material models to simulate the process of deformation, damage and failure of polymer matrix composites (PMCs) under impact conditions is becoming critical as these materials are gaining increased usage in the aerospace and automotive industries. Experimental stress vs. strain curves are needed at different strain rates for progressive damage modeling of dynamic failure. Matrix-dominated deformation modes are particularly challenging as they exhibit nonlinear behavior and rate dependence. In particular, in-plane shear is known to exhibit significant nonlinear response due its matrix dominant deformation leading up to failure. The purpose of this work is to experimentally characterize the in-plane shear deformation response of woven carbon/epoxy fabrics under intermediate strain rates (10-1 to 100 s-1). For this work, plain weave carbon fabrics with 3k and 12k tows are manufactured by VARTM. Testing is done using a servo-hydraulic load frame and 2D digital image correlation (DIC) is used to obtain experimental stress vs. strain curves following ASTM D7078M. Comparison between quasi-static (10-3 s-1) and intermediate experimental stress strain curves show an increase in ultimate strength and no significant change in modulus with increased loading rate. Investigations into the development of areas of localized high strain are observed which are attributed to the growth of meso-scale fiber tows damage. Surface level measurements from DIC and qualitative observations from high speed camera imaging reveal that cracks initiate and develop in the matrix gap between tows and at fiber undulation regions of the plain weave. These then develop into bulk cracks that grow parallel to the load. Higher loading rates have shown increased strength under in-plane. In conclusion, 2D DIC and the v-notched shear test method was able to characterize rate effects under intermediate shear loading of woven polymer matrix composites deformation response. High resolution DIC reveals localized mesoscale strain inhomogeneity that plays a key role in the initiation and evolution of bulk fracture in woven composite architecture which was captured for well for the 12k tow material.
