Boron Carbide Whisker and Platelet Reinforced Ceramic Matrix Composites

Abstract

Boron carbide whisker and platelet reinforced alumina and boron carbide whisker reinforced silicon carbide composites were prepared by hot-pressing. the mechanical properties of hot-pressed boron carbide platelet and whisker reinforced composites are better than the inherent ceramic matrix. a maximum fracture toughness, KIc of 9.5 MPam1/2 is achieved for alumina/boron carbide whisker composites, 8.6 MPam1/2 is achieved for alumina/boron carbide platelet composites and 3.8 MPam1/2 is achieved for silicon carbide/boron carbide whisker composites. the fracture toughness is dependent on the volume fraction of the platelets and whiskers.
