Title

Abstract

Reinforcing ceramic materials with unidirectionally aligned continuous fibers improves the mechanical characteristics in the fiber direction but often results in reduced transverse strength and fracture toughness. The effect of randomly dispersed fine whiskers on unidirectional fiber reinforced ceramic matrix composites, resulting to hybrid ceramic matrix composite (HCMC), was studied. Substantial improvement to the transverse fracture toughness of a continuous fiber reinforced ceramic matrix composite through the introduction of whiskers to the matrix was demonstrated. HCMCs displayed a 99% increase in fracture toughness for a crack propagating along the fiber direction and an 82% increase for a crack propagating across the fibers.
