Abstract
AlN/BN laminated ceramic composites were fabricated using tape-casting and
hot-pressing by optimizing the designs of the structure and geometry of AlN/BN laminated ceramic
composites. The results showed that the fracture toughness and bending strength for AlN/BN
laminated ceramics reached 9.1MPa.m1/2 and 378MPa respectively. The fracture toughness is two
times higher than that of AlN monolithic ceramics. The excellent fracture toughness of AlN/BN
laminated ceramics could be mainly attributed to crack deflection, delaminating, branching, parallel
propagation and crack laminate pilling out at the AlN/BN weak interface.
