粉煤灰是火力发电厂产生的大量废弃物，一直是处理问题的难题。本研究的目的是有意义地利用粉煤灰作为纯环氧树脂基体和 20% 环氧苯酚腰果壳液 (EPCNSL) 增韧环氧基体中的填料。考虑的特性是冲击、压缩和吸水性。复合材料由不同比例的环氧树脂中的粉煤灰和 20% EPCNSL 增韧环氧树脂制成。压缩性能根据 ASTM 程序在计算机万能试验机上测量。使用悬臂梁冲击试验机测定无缺口样品的冲击强度。与纯环氧-粉煤灰复合材料相比，填充粉煤灰复合材料的增韧基体显示出更高的压缩模量。增韧基复合材料比纯环氧-粉煤灰复合材料表现出更好的吸水性能。
Fly ash, a waste product generated in a thermal power plant in huge quantities has been posing problems of disposal. The purpose of this study is to make a meaningful utilization of fly ash as the filler in pure epoxy resin matrix and 20% epoxy phenol cashew nut shell liquid (EPCNSL)toughened epoxy matrix. The properties under consideration are impact, compression, and water absorption. Composites are made with varying proportions of fly ash in epoxy resin and 20% EPCNSL-toughened epoxy resin. The compression properties are measured on a computerized universal testing machine according to ASTM procedure. The impact strength is determined using an izod impact tester for unnotched specimens. The toughened matrix filled with fly ash composites shows improved compression modulus over pure epoxy–fly ash composites. The toughened matrix composites show better water absorption property over pure epoxy–fly ash composites.
