Summary

Silica matrix composites have been developed using sol-gel technique with glass and quartz fabric as reinforcement and two types of sols. Infiltration has been done using EPD. SEM investigation shows well bonded matrix microstructure around the fibers as well as interlaminar bonding. The composites fabricated with colloidal silica sol show better adhesion, possess more than 60% sintered density, and exhibit high fracture toughness and electrical properties. Composites made with glass fibers exhibit better properties than those fabricated with quartz fibers due to sensitive surface of latter fibers.
