摘　　要：目前很难对晶须增韧陶瓷复合材料的断裂韧性进行理论计算。本文同时考虑裂纹和气孔对材料断裂韧性的影响,建立了理论计算复合材料断裂韧性的公式,从而为在复合材料的研制过程中预估其断裂韧性奠定了理论基础,减少因反复实验而造成的人力和财力的浪费,加速复合材料的研制过程。It is very difficult to compute fracture toughness for silicon carbide whisker reinforced ceramic composite theoretically so far. Theoretical model for calculating fracture toughness has been set up on the basis of consideraion of the effect of microcrack and pore on fracture toughness. The model establishes theoretical basis for predicting fracture toughness of the composite to be devefoped which will decrease manpower and resource waste and accelerate the devefopment of new composite.
