Summary

Fused silica reinforced by Textron SCS-6 SiC fiber was prepared by a simple slip casting and sintering process. Fiber volume concentrations below 5% were found to be sufficient to raise room temperature tensile strengths by a factor of four, and to significantly improve static load creep resistance over monolithic fused silica. Microstructure analysis coupled with damping measurements reveal considerable debonding occurring in the fiber-matrix interface. Strengthening appears to be dependent on the interfacial frictional forces.
