EFFECT OF CURING AGENT CONTENT ON RTM EPOXY SYSTEM CURING PROPERTIES

  • Online:2009-11-28 Published:2009-06-25

摘要:

本文通过对普通双酚A型环氧树脂进行改性和添加自制液体胺类固化剂的方法,制备出一种RTM环氧树脂体系

, 并通过DMA、万能材料试验机考察了固化剂含量对该环氧树脂体系固化特性的影响。研究结果表明,当固化剂含

量较低或较高时,环氧树脂体系Tg均较低。当树脂与固化剂配比为100∶31时,玻璃化转变温度最大,约为92.4℃

,此时,该环氧树脂体系也具有较好的综合力学性能。

关键词: RTM, 环氧树脂, 固化剂含量, 固化性能

Abstract:

In this paper, the RTM epoxy system had been synthesized by modifying Bisphenol A epoxy

and adding a kind of amine curing agent. The effect of curing agent content on the performance of

epoxy system were studied by DMA and mechanical testing machine. The results showed that, the glass

transition temperature was low whenever curing agent content was higher or lower,but when the ratio

of epoxy and curing agent was 100∶31, the maximum glass transition temperature of the system was

about 92.4℃, and the mechanical properties of the system were good.

Key words: RTM, epoxy resin, curing agent content , curing performance
