This book was released on 2018-07-02 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: A number of studies have investigated the thermo-oxidative behavior of polymer matrix composites. Two significant observations have been made from these research efforts: (1) fiber reinforcement has a significant effect on composite thermal stability; and (2) geometric effects must be considered when evaluating thermal aging data. A compilation of some results from these studies is presented, and this information shows the influence of the reinforcement fibers on the oxidative degradation of various polymer matrix composites. The polyimide PMR-15 was the matrix material that was used in these studies. The control composite material was reinforced with Celion 6000 graphite fiber. T-40R graphite fibers, along with some very stable ceramic fibers were selected as reinforcing fibers because of their high thermal stability. The ceramic fibers were Nicalon (silicon carbide) and Nextel 312 (alumina-silica-boron oxide). The mechanical properties of the two graphite fiber composites were significantly different, probably owing to variations in interfacial bonding between the fibers and the polyimide matrix. The Celion 6000/PMR-15 bond is very tight but the T-40/PMR-15 bond is less tight. Three oxidation mechanisms were observed: (1) the preferential oxidation of the Celion 6000 fiber ends at cut surfaces, leaving a surface of matrix material with holes where the fiber ends were originally situated; (2) preferential oxidation of the composite matrix; and (3) interfacial degradation by oxidation. The latter two mechanisms were also observed on fiber end cut surfaces. The fiber and interface attacks appeared to initiate interfiber cracking along these surfaces. Bowles, Kenneth J.

Available in PDF, EPUB and Kindle. Book excerpt: Annotation Over the past three decades, the terminology of composite materials has been well acknowledged by the technical community, and composite materials have been gaining exponential acceptance in a diversity of industries, serving as competitive candidates for traditional structural and functional materials to realize current and future trends imposed on high performance structures. Striking examples of breakthroughs based on utilization of composite materials are increasingly found nowadays in transportation vehicles (aircraft, space shuttle and automobile), civil infrastructure (buildings, bridge and highway barriers), and sporting goods (F1, golf club, sailboat) etc., owing to an improved understanding of their performance characteristics and application potentials, especially innovative, cost-effective manufacturing processes. As the equivalent of ICCM in the Asian-Australasian regions, the Asian-Australasian Association for Composite Materials (AACM) has been playing a vital leading role in the field of composites science and technology since its inception in 1997 in Australia. Following the excellent reputations and traditions of previous ACCMs, ACCM-4 is held in scenic Sydney, Australia, 6-9 July 2004. The theme of ACCM-4, Composites Technologies for 2020, provides a forum to present state-of-the-art achievements and recent advances in composites sciences & technologies, and discuss and identify key and emerging issues for future pursuits. By bringing together leading experts and promising innovators from the research institutions, end-use industries and academia, ACCM-4 intends to facilitate broadband knowledge sharing and identify opportunities for long-term cooperative research and development ventures. The scope of ACCM-4 is broad. It includes, but is not limited to, the following areas: Bi- composites, Ceramic matrix composites, Durability and aging, NDE and SHM Eco-composites, Manufacturing and processing technologies, Industrial applications, Interphases and interfaces, Impact and dynamic response Matrices (polymers, ceramics, and metals), Mechanical and physical properties (fatigue, fracture, micromechanics, viscoelastic behavior, buckling and failure, etc.), Metal matrix composites, Multi-functional composites, Nano-composites, Reinforcements (textiles, strand, and mat), Smart materials and structures, Technology transfer (education, training, etc.)
