提出了一种新的方法，适用于在进行单纤维试验之前，沿标距沿着测定纤维直径。该测量对于评估机械性能（如杨氏模量、强度和时间依赖性失效）非常重要。在拉伸测试之前测量Nextel 720（3M）铝硅酸盐陶瓷纤维的直径分布。结果发现，直径分布模式沿着每个纤维是不同的非系统性从其他纤维。杨氏模量的可靠性受到用于应力测定的代表性直径的强烈影响。
A new method is presented suitable for determining fiber diameters along the gauge length before conducting single fiber tests. This measurement is important to evaluate mechanical properties such as Young's modulus, strength and time‐dependent failure. Diameter distributions were measured for Nextel 720 (3M) alumino‐silicate ceramic fibers before the tensile tests. It was found that diameter distribution pattern along each fiber was different nonsystematically from other fibers. Reliability of Young's modulus was strongly affected by the representative diameter used for the stress determination.
