Description

Fundamental scientific issues remain to be addressed to enable the development of a full range of high-performance ceramics and ceramic-matrix composites for Air Force air and space applications. These issues encompass basic design, new constituents, compatible chemistries, and enabling processes for oxide and nonoxide ceramic matrix composites. Over the past fifteen years, research in our laboratory has focused on the development and characterization of viable oxide-based fiber coatings for controlling, debonding, and establishing sufficient understanding of processing/structure/property relationships for composite system design. Current research focuses on investigating higher temperature nonoxide fiber and matrix constituents for enhanced durability, development of oxide fiber coatings and interface control, developing fabrication processes specifically for nonoxide composites, investigating the stability of consitituents in aggressive environments, and understanding those key environmental effects on constituent-level behavior that affects life in relevant service environments. Modeling of ceramic matrix composite fabrication processes is of particular interest. Intended service environments for these composites include turbine engines and scramjet engines, as well as hot structures and thermal protection systems for hypersonic vehicles.
