Summary

CVD silicon carbide monofilaments designed for use in Metal Matrix Composites, have been studied using Electron Microscopy, Electron Microprobe Analysis (EPMA) and Raman Microprobe. Longitudinal thermal expansion and bend stress relaxation (BSR) tests have also been performed. The monofilaments studied were Textron Ultra-SCS and an experimental DERA Sigma fiber referred to as DERA-SF. The Ultra-SCS shows a continually varying radial carbon content, thought to be responsible for its high strength and good creep resistance. The DERA-SF fiber is stoichiometric and exhibits similar BSR behavior to SCS-6. All monofilaments have similar longitudinal coefficients of thermal expansion of 5×10-6K-1.
