Abstract
This chapter discusses the advantages of metal-matrix composites (MMC), and compares them with their base metals and polymer-matrix composites. It divides MMCs according to the type of reinforcement. The reinforcement can be particulates, high strength single crystal whiskers, short fibers, long aligned multifilaments, or monofilament fibers. The primary MMC fabrication processes can be classified as either liquid phase or solid state processes. Liquid phase processing is considerably less expensive than solid state processing. The chapter discusses the characteristics of liquid phase processed discontinuous MMCs, and describes various liquid phase processes including casting processes, liquid metal infiltration, and spray deposition. The chapter also provides a relative comparison of composite performance with materials and process technologies for a number of MMCs. It further discusses glass laminate aluminum reinforced (GLARE), which is a type of aluminum fiber metal laminate, in which unidirectional S-2 glass fibers are embedded in FM-34 epoxy structural film adhesive. The primary advantages of GLARE are also provided.
