一、前言以树脂为基体的纤维增强复合材料的动态模量与静态模量似有一定的差别,只有准确地测定复合材料的动态模量,才能保证复合材料结构的动力分析有更高的精度。因此,如何测定
I. Introduction There are some differences between the dynamic modulus and the static modulus of resin-based fiber-reinforced composites. Only by accurately measuring the dynamic modulus of the composite material can the dynamic analysis of the composite structure be ensured with higher accuracy . Therefore, how to measure
