纤维增强复合材料的性能不仅取决于增强纤维的强度，而且还取决于纤维强度的分布。在这项研究中，测量了几批Nextel（TM）610和Nextel（TM）720陶瓷纤维的单丝强度。断裂统计数据与标距长度和直径变化的影响相关，并使用几种不同的技术计算威布尔模量。结果发现，在一个单一的标距长度测得的威布尔模量没有准确地预测无论是标距长度或直径的拉伸强度的依赖性。
The properties of fibre-reinforced composites are dependent not on ly on the strength of the reinforcement fibre but also the distribution of fibre strength. In this study, the single filament strength of several lots of Nextel(TM) 610 and Nextel(TM) 720 ceramic fibres was measured. Fracture statistics were correlated with the effects of gauge length and diameter variation, and the Weibull modulus was calculated using several different techniques. It was found that the measured Weibull modulus at a single gauge length did not accurately predict either the gauge length or diameter dependence of tensile strength.
