Summary

Mixed carbides of Si, Zr and Ta have been developed using sol gel method. Metalalkoxides of these metals have been cohydrolysed with addition of a carbonaceous source in appropriate ratios. These modified gels have been heated to 1000°C-1700°C. The transformation taking place have been studied using FTIR, XRD and SEM. Carbon fibers and silicon carbide fibers reinforced composites were made with these modified gels and subsequently heat treated to different temperatures up to 1700°C. The composites so made exhibited density in the range of 1.5–1.8 g/cc. The bonding between fibers and matrix was found to be not very strong which on mechanical testing revealed mixed mode fracture.
