Fracture Toughness of Fibrous Si3N4 Monolithic Ceramics

Abstract:

Article Preview

Fibrous Si3N4 monolithic ceramics with a hexagonal cell were fabricated in the preferred orientation. The densified Si3N4 fibrous monolithic showed fracture toughness of 17 MPam1/2. An application of SiC whisker as reinforcement exhibited higher fracture toughness (24 MPam1/2). The influences of fiber diameter and reinforcement on the fracture toughness of these fibrous monolithic ceramics were studied in details.
