摘要
因为单向炭纤维增强树脂基复合材料(UD-CFRP)属于脆性材料,它的力学性能如层间剪切强度(ILSS)的大小依赖于UD-CFRP中随机分布的缺陷。本文使用经典的Weibull分布理论研究了CF表面处理对UD-CFRP之ILSS的影响,并用线性回归的方法对函数进行参数估计。CF经表面处理后,UD-CFRP之ILSS增加约50%;Weibull模数m增加约1.5~2倍;Cv值大为下降。
Because carbon fibers reinforced plastic(CFRP)composites belong to brittle materials their mechanic properties such as interlaminar shear strength (ILSS)depend on stochastic defects. The classical Weibull distribution theory was employed to study the influence of carbon fiber surfaee treatment on ILSS of UD-CFRP ,to estimate the parameters of the distribution with linear regression.Afler surface treatmrnt of carbon fiber,the ILSS of UD-CFRP composites has increased about 50%,Weibull modulus,about 1. 5  ̄2times and coefficient variation decreased greatly.
