摘　　要：用韦伯理论评价了碳纤维的抗拉强度和分散,验证了形状参数 m 和强度离散的关系。同时,探讨了体积效应和碳纤维强度离散,证实了细度离散对强度离散的影响。The tensile trength and its variation of carbon fibers are evaluated by Weibull distribution,the rela- tionship between Weibull's modulus and variation of fibers strength is proved.Meanwhile,the size effect and dispersity of carbon fibers strength are discussed,and the effect of fineness variation on the strength variation is also verified.
