Abstract
A two layered Al2O3, /SiC composite is prepared. The composite consists of un-reinforced Al2O3, layer and 10 Vol%-SiC whisker reinforced Al2O3, layer, which are simultaneously sintered by hotpressing. Flexural strength of the composite reaches 300MPa and diffrence fracture toughness Kic: are observed for two layers, namely, 5MPam1/2 for reinforced layer and 2MPam1/2 for un-reinforced layer, respectively. Also, thermal stresses resulted in during cooling down to room temperature is discussed.
