3-D Braided, Continuous Fiber Ceramic Composites Produced by Chemical Vapor Infiltration

Abstract

Continuous fiber reinforced ceramic composites have been successfully fabricated by chemical vapor infiltration of silicon carbide and silicon nitride matrix materials. Fiber preforms were three dimensionally braided with Nicalon(TM) and Nextel(TM) fiber materials forming a network of through thickness fiber architectures. Three unique material compositions were produced with the objective of demonstrating the capability of braiding brittle ceramic fibers and producing quality composites structurally capable of performing in a ballistic environment. It is anticipated that the continuous fiber architecture will be a significant technical advantage towards improvements in ceramic armor applications where non-catastrophic failure and increased toughness are a concern.
