Two-layered hybrid composites, the Al2O3 layers containing different amounts of SiC whisker, were prepared by hot-pressing the two layers simultaneously. Outstanding improvement was observed in the strength and fracture toughness of composites when one of the layers is reinforced by 10vol% whisker addition. The difference of the fracture toughness between the layers in the composite is also observed. The effects of residual stresses resulting from the thermal expansion mismatch between two layers were discussed.
