... Metal-matrix composites (MMCs) are metals that are usually reinforced with ceramic fibers or particles to enhance or customize properties such as stiffness, strength, thermal conductivity, thermal expansion, friction, and wear resistance. MMCs, however, are generally more prone to corrosion...

... Lightweight composite stone-faced honeycomb panels, typically consisting of nominally ¼ in. (6 mm) thick stone adhered to a honeycomb panel, have been successfully used in exterior cladding applications since the mid-1980s. However, as new manufacturers of these products are regularly introduced...

... A case study is presented on the practical application of infrared thermography during fatigue testing in the measurement of specimen temperature fluctuations during fatigue of polymer matrix composites. It is demonstrated that such measurements can also be integrated with an outer loop test...

... Physical and mechanical testing was conducted on composite stone faced aluminum honeycomb panels manufactured in the United States for use as exterior veneer panels on buildings. Testing was conducted on specimens cut from new stone faced panels as well as stone faced panels removed from service...

... concentration in the outer component of the two studied Duplex types. The effect of difference in Sn concentration on hydride distribution observed from studies of unirradiated claddings has, however, not been confirmed by the hot-cell studies presented here. Duplex cladding composite corrosion hydride...

... An experimental evaluation of the dynamic fracture properties of an automotive epoxy is presented. Pronounced stick-slip behavior was observed in both quasi-static and impact tests of aluminum and composite adherends bonded with this adhesive. An experimental technique for conducting low speed...

... Probabilistic computational simulation of fatigue-life is illustrated in terms of several sample cases that have been generated over the past ten years. The cases are selected to illustrate applications to multi-scale, multi-discipline, and multi-physics. These cases include composite laminate...

... Coefficient of thermal expansion (CTE) mismatch between metal and composite is a major barrier for use of composites in applications that require a metal liner. The situation is critical for cryogenic applications because of the large temperature excursion to which the pipe is subjected...

... composite test specimen with an artificial delamination subjected to bending loads to characterize when a delamination will extend. When the displacements become large, the linear theory used to analyze the results of the test yields errors in the calculated toughness values. The current standard places...

... This paper discusses a new multi-axial 10.2-cm (4-in.) composite tube test method. This test method is capable of loading a 10.2 cm composite tube by internal pressure, torsion, and tension/compression. The method improves on an older biaxially loaded (internal pressure and axial load) tube...

... The general aviation approach was taken in these material qualifications, where it is assumed that a large portion of composite material property batch-to-batch variability can be reproduced in the laboratory through independent layup and cure of panels, termed a process lot. A nested...

... A fully automated thermomechanical fatigue test system capable of extremely sensitive crack growth measurements was developed. This system was used to conduct thermomechanical fatigue tests on titanium matrix composites to study the crack growth behavior throughout cyclic testing as well...

..., a prediction of failure on-set was performed. The predicted failure initiation load for the [0 2 /90 2 /45 2 /-45 2 ] s stacking sequence was approximately 40% higher than the predicted failure initiation load for the [0 2 /45 2 /90 2 /-45 2 ] s stacking sequence. composite bolted joint three...

... biocompatibility. The bone response to the polymers and composites was very similar. Histology showed that new bone was formed at the defect site, which grew up to the material surface and remodelled into new physiological bone tissue. The rate of degradation of the poly-L-lactide and it's composite with tri...

... This paper provides a review of two recent studies undertaken to examine the oxidation behavior of monolithic SiC and SiC-SiC composites in simulated and actual gas turbine environments. In the first study, a high-pressure and high-temperature test facility was used to expose a variety...

... The evolutionary path of ceramic matrix composites (CMCs) to viable candidate materials for current engineering designs of today and tomorrow has been littered with appropriate and inappropriate theoretical models, useful and useless test methods, and hopeful and hopeless materials systems...

... An experimental investigation was performed to determine the behavior of an open-hole tension (OHT) graphite/bismaleimide composite specimen loaded in tension-tension fatigue under isothermal, fixed-frequency conditions. A range of stress levels and temperature levels was chosen to assess...

... Art, in the form of sculpture and masonry murals, has been and is often made from composite materials. Natural fiber materials are used often for sculpture and murals. Examples of art are discussed in relation to most of the important topics of the symposium: fracture by impact; thermal fatigue...

... A carbon fiber-reinforced polyetheretherketone (PEEK) composite acetabular cup was fabricated by injection molding. An extensive hip joint simulator test was conducted to evaluate the tribological performance of this CF-PEEK composite cup as a potential orthopaedic bearing surface. Hip joint...

... The applicability of ASTM Test Method for Shear Strength of Continuous Fiber-Reinforced Advanced Ceramics at Ambient Temperatures (C 1292) was investigated to determine the shear strength of one-dimensional and two-dimensional continuous fiber-reinforced ceramic composites. The advantages...
