DARPA has identified a need for new and improved techniques for coating ceramic fibers for subsequent incorporation into metallic, ceramic or hybrid matrices. American matrix, inc.'s phase I program addresses the significant performance attributes (defined by DARPA as interface chemical reaction inhibition, interface bond development, and tailored properties) with a multi-faceted coating program. Selecting sic discontinuous fibers as the coating vehicle, American matrix will investigate the feasibility of using organo-chlorosilane coupling agents, liquid phase metalorganics, and selected metals as coating agents. Proprietary application and bonding processes will be used to apply the coatings to the fibres. A comprehensive evaluation program will be used to determine the best coating system and permit selection of candidate systems for a phase ii development program.
