Abstract

The dependence of the hardness of epoxy–sand composite on the amount and dispersion of its sand component is studied. The effect of the hardness of the composite on its abrasive wear resistance is studied. It is shown that the wear resistance of the composite decreases with an increase in its hardness; i.e., this dependence is not linear and does not correspond to conventional considerations.

环氧树脂-砂复合材料组分的浓度和颗粒分散度对硬度的影响及其与耐磨性的关系

摘要

研究了环氧-砂复合材料的硬度对其砂成分的数量和分散度的依赖性。研究了复合材料的硬度对其耐磨性的影响。结果表明，复合材料的耐磨性随其硬度的增加而降低。即，这种依赖性不是线性的，并且不符合常规考虑。
