Abstract: 

The mechanical properties of ZrB2-SiC/SiCw layered ceramics obtained by strip casting and hot pressing are studied. In the ceramics, ZrB2-SiC layers and ZrB2-SiCw layers alternate. The bending strength and fracture toughness of the ceramics can reach 360 MPa and 10.83 MPa·m1/2, respectively. It is shown that, compared with ZrB2-SiC monolithic ceramics, the improvement in fracture toughness is explained by SiC whiskers and layered structure.
