Abstract Despite the relatively high erosion resistance of elastomers, few studies have considered using them as reinforcements for polymer composites. This study investigated the erosion of rubber particle-reinforced epoxy composites by angular silicon carbide particles. The erosion rates were found to be significantly lower than the neat epoxy for all tested conditions. Using the erosion rates of the two constituents, a new mixture rule based on the reinforcement areal coverage predicted the erosion rates to within 0.5%–10% of those measured. The areal coverage depended on the reinforcement size and volume fraction and could be accurately predicted assuming a random reinforcement distribution. The methodology may be an effective tool for the prediction of the erosion rate of other composites with elastomeric reinforcements.

模拟橡胶颗粒增强环氧树脂的固体颗粒侵蚀

摘要 尽管弹性体具有相对较高的耐腐蚀性，但很少有研究考虑将它们用作聚合物复合材料的增强材料。本研究调查了角形碳化硅颗粒对橡胶颗粒增强环氧树脂复合材料的侵蚀。发现在所有测试条件下，侵蚀率都显着低于纯环氧树脂。使用两种成分的侵蚀率，基于钢筋面积覆盖率的新混合规则预测侵蚀率在测量值的 0.5%–10% 内。区域覆盖率取决于钢筋尺寸和体积分数，并且可以假设随机钢筋分布进行准确预测。该方法可能是预测具有弹性增强材料的其他复合材料的侵蚀率的有效工具。
