摘要

要开发和应用直径小（小于 15 μm）、弹性模量超过 50 GPa 的增强纤维，就必须确定其机械性能。然而，在通过移动夹具（十字头移动）测量纤维变形时，由于量规长度（夹具之间的距离）对静态模量的比例效应，大多数传统方法都难以适用于此类物体。本文研究了几种先进的高模量纤维，包括 Twaron 和 Armos，并介绍了一种根据测量值计算实际模量的模型。为了验证该模型，对几种芳纶纤维进行了实验测试。

Methodological Challenges in Accounting for Test\ Conditions When Determining the Static Elastic Modulus of Advanced Aramid Structural Fibers

To develop and implement reinforcing fibers of small diameter (less than 15 μm) and an elastic modulus exceeding 50 GPa, it is necessary to determine their mechanical properties. However, most of the conventional methods are challenging to apply to such objects due to the scale effect of the gauge length (distance between grips) on the static modulus when measuring fiber deformation by moving the grips (crosshead movement). This paper examines several advanced high-modulus fibers, including Twaron and Armos, along with introducing a model for calculating real modulus from measured values. To validate the model, experimental tests were carried out for several aramid fibers.
