摘　　要：应用概率的拟合方法检验了闸瓦复合材料压缩弹性模量和压缩强度的分布 ,其分布分别遵循Eu=0和σu=0的Weibull分布 ,并估计了它们的分布参数。探讨了配方二的弹性模量与强度之间的相互关系 ,及在均值意义下 ,不同配方的弹性模量和强度之间的相互预测 ,预测结果具有满意的精度。It has been proved by the probabilistic method of fit test in this paper, that the compressive elastic modulus and strength of the brake lining matherials compressive followed Weibull distributions of E u=0 and σ b=0 respectively. The parameteres of the Weibull distribution have been estimated. The elastic modulus and strength of composites could be predicted accurately for various formulas. The way of improving formula has also been suggested.
