5.4 Chemical Vapor Infiltration Processing of Ceramic Matrix Composites

Carbon/carbon and ceramic-matrix composites are frequently processed by chemical vapor infiltration, a technique that ensures a very good quality of the interphase and matrix, while preserving the fibers. We review in this chapter the principle and several implementations and applications of this process; in a second part, a more precise description of the physico-chemistry and the bases of process modeling are treated.
