Abstract

The authors obtained and studied samples of a composite material based on epoxy resin ED-20 with PEPA hardener and hemp fiber as a filler. Analysis of changes in the effective modulus during deformation up to fracture of the sample was carried out. Identified several stages with a different nature of its change, which indicates the complex nature of the deformation process with repeated changes in the mechanisms of deformation.

含麻纤维填料的环氧树脂基材料的应力松弛和蠕变

摘要

作者获得并研究了基于环氧树脂ED-20的复合材料的样品，该材料以PEPA硬化剂和大麻纤维为填充剂。进行了直至样品断裂的变形期间有效模量的变化的分析。确定了具有不同变化性质的几个阶段，这表明变形过程具有反复变化的变形机制的复杂性质。
