PES增韧高性能环氧树脂力学性能研究
Engineering Plastics Application（2012）
Abstract
利用聚醚砜(PES)增韧环氧树脂(EP),制备了TDE–85 EP/四官能团EP/双酚A固体EP/PES共混体系(以下简称EP/PES共混体系),对EP/PES共混体系的微观形貌进行了表征,研究了PES用量及TDE–85 EP/四官能团EP/双酚A固体EP质量比对EP/PES共混体系力学性能的影响。结果表明,加入一定量的PES可提高EP的强度和韧性且基本不影响EP的模量,当PES用量为8份时,EP/PES共混体系具有较高的拉伸强度和断裂伸长率。当TDE–85 EP/四官能团EP/双酚A固体EP的质量比为70/5/25时,EP/PES共混体系的拉伸强度和断裂伸长率最高。
