Abstract

Composition and features of manufacturing samples of epoxy–sand composite used for field repair of road-building machines are considered. Results of determining the impact strength of epoxy–sand composite samples are presented. It has been shown that the presence of dispersed filler has a slight effect on the impact strength values. It has been established that specimens with the lowest concentration of dispersed filler have the best viscoelastic characteristics.

道路机械修复用环氧砂复合材料粘弹性特性的测定

摘要

考虑了用于筑路机械现场修复的环氧砂复合材料制造样品的成分和特征。给出了环氧砂复合材料样品冲击强度的测定结果。已经表明，分散填料的存在对冲击强度值有轻微影响。已经确定，分散填料浓度最低的样品具有最佳的粘弹性特性。
