摘要
本文通过测试两种胺类固化体系制得的浇注体和复合材料试样的弯曲性能,初步对比多胺与改性胺固化体系的性能优劣,进而在设定固定加载频率后采用三点弯曲疲劳加载的方式测得试样模量下降趋势,对比了多胺与改性胺固化体系复合材料弯曲疲劳性能。
In this paper,through bending property test of two kinds of amine cured epoxy casting and composite samples,a comparison of polyamines and modified amine curing system has been made.Then under fixed loading frequency,three point bending fatigue test was conducted to compare the sample's modulus and the bending fatigue performance.
