CERAMIC MATRIX COMPOSITES Ceramic Matrix Composites

Reviewed here are 17 of the latest reports of research on the fabrication and properties of ceramic matrix composites, special materials developed over the past quarter century. What is revealed is a body of university and industrial efforts at instrumentation-intensive research on man-made materials that still have limited and problematical uses, though illusive promises of magical performance, innumerable applications, and lucrative sales entice approaching researchers, anxious for reward, like Sirens beckoning to mariners. Dangers lurk.

Ceramic matrix composites (CMCs) are space-age, three-decker sandwich materials useful in applications requiring resistance to heat and certain (moderate) structural stresses. Aerospace vehicle skins, oven walls, automotive brake shoes, and certain flues and ducts for hot gases are obvious applications. Composites are a base matrix material, usually the ceramic part; an organic or inorganic-organic fiber attached to the outside of, or impregnated within, the matrix; and--in the latest versions--an interphase, third material to protect one or both of the other two and to bind them together. The best overview of the art of fabricating these materials and researching ever-improved versions is that by Naslain (13). The brochure by AlliedSignal, Inc. (ASI, hereafter) exposes the leading edge of fabrication and achievement of superior strength, heat resistance, oxidation resistance, and toughness (1). Those interested in researching fiber manufacture and improvements for the purposes of building even better composites should be encouraged, because: "Fibres [sic] and interphases have not been yet fully identified. Conversely, various oxide matrices . . . have already been studied and processing techniques are available" (13:485). Both unfortunate but encouraging as it may be, most of the work reported was devoted to matrix substances, not the fiber materials.
