Tensile test is conducted on environmentally pollutant crumb rubber/epoxy composite. Crumb rubber particles with different volume fractions (10, 20 and 30%) are reinforced with epoxy matrix. Stress-strain curves reveal brittle fail for all the samples. Crumb rubber filled epoxy composites reveal higher modulus (13%–28%) and strength (28%–44%) than neat epoxy sample. Epoxy with 30 volume % of crumb rubber depicts higher modulus and strength compared with all other compositions, exemplifying use of crumb rubber for utilarian applications. Crumb rubber/epoxy composites register higher specific modulus and strength for all compositions in comparison with neat epoxy. Scanning electron micrographs of test samples are used to analyze property - composition correlations. Finally, property map is plotted to compare the results of present study with existing ones to highlight the efficacy of the proposed composites.

对环境污染的胶粒/环氧复合材料进行拉伸试验。具有不同体积分数（10%、20% 和 30%）的碎胶颗粒用环氧树脂基质增强。应力-应变曲线显示所有样品的脆性失效。碎胶填充的环氧树脂复合材料显示出比纯环氧树脂样品更高的模量 (13%–28%) 和强度 (28%–44%)。与所有其他组合物相比，具有 30 体积 % 碎胶的环氧树脂表现出更高的模量和强度，举例说明碎胶在实用应用中的用途。与纯环氧树脂相比，碎胶/环氧树脂复合材料的所有组合物都具有更高的比模量和强度。测试样品的扫描电子显微照片用于分析性能-组成的相关性。最后，
