中文摘要	ZrB2/MO laminated composites, in which ZrB2 containing 10 vol% nano-SiC whiskers and 10 vol% SiC particles were taken as matrix layer and Mo as interfacial layer were prepared by roll-compaction and hot-pressing sintering at 1950 degrees C for 1 h under 20 MPa pressure in flow argon. The results show that the ZrB2/MO laminated composites have a high fracture toughness of 9.3 +/- 0.21 MPa-m(1/2), and the bending strength can be increased to 400 36 MPa by the addition of Si and B into the Mo layers, which would avoid cracking from layer interface and improve the brittlement of Mo at room temperature. The main mechanisms of enhancing toughness are attributed to crack bluntness, crack deflection, and crack parallel propagation along interfacial layers. MoB, ZrB and Mo5SiB2 were formed as the reaction among ZrB2, SiC and Mo, which would limit the increase of the strength and toughness.
