介绍了一种表征直径沿着长度方向变化的脆性单丝强度的模型。该模型允许使用一个假想的均匀直径，即“代表性直径”，以单模态威布尔分布来缩放纤维强度。使用代表性直径的优点在于，尽管真实的纤维具有可变直径，但脆性单丝的断裂概率与长度相关。研究结果表明，变径是影响强度分布的重要因素。因此，预期直径的均匀性对于上级增强纤维生产是必要的。
A model to characterize the strength of brittle monofilaments that possess a variation in diameter along their length was introduced. The model enabled use of an imaginary uniform diameter, i.e. ‘representative diameter’ to scale the fiber strength with single-modal Weibull distribution. The advantage of using the representative diameter is that the fracture probability of brittle monofilaments is correlated with the length although the real fibers possess a variable diameter. The present results revealed that the variable diameter was an important factor affecting the strength distribution. Thus, the uniformity in the diameter was expected essential for superior reinforcement fiber production.
