TLDR
In this paper, the high strength/weight and stiffness/weight properties of resin, metal, and ceramic matrix composites will play an increasingly key role in meeting the performance requirements of subsonic, supersonic, and hypersonic aircraft.Abstract:
Advanced aircraft engine research within NASA Lewis is being focused on propulsion systems for subsonic, supersonic, and hypersonic aircraft. Each of these flight regimes requires different types of engines, but all require advanced materials to meet their goals of performance, thrust-to-weight ratio, and fuel efficiency. The high strength/weight and stiffness/weight properties of resin, metal, and ceramic matrix composites will play an increasingly key role in meeting these performance requirements. At NASA Lewis, research is ongoing to apply graphite/polyimide composites to engine components and to develop polymer matrices with higher operating temperature capabilities. Metal matrix composites, using magnesium, aluminum, titanium, and superalloy matrices, are being developed for application to static and rotating engine components, as well as for space applications, over a broad temperature range. Ceramic matrix composites are also being examined to increase the toughness and reliability of ceramics for application to high-temperature engine structures and components.read more

Friction and wear of fiber-reinforced metal—matrix composites
TL;DR: In this paper, the friction and wear behavior of three uniaxial metal-matrix composites (graphite/Al, stainless steel/Al and Al 2 O 3 /Al-Li) were investigated unidirectional sliding tests were conducted in the three principal orientations (longitudinal, transverse, and normal).

Polymer Matrix Materials
TL;DR: Advanced Resin Matrix Composites (ARMCs) as discussed by the authors are a class of composites constructed by matrix resins and continuous fiber reinforcements, which can provide a series of extraordinary advantages including high specific strength and stiffness, designable properties, fatigue and corrosion resistance as well as special electric-magnetic performance.
