碳纤维对环氧树脂固化反应过程的影响
INFLUENCE OF CARBON FIBER IN EPOXY RESIN CURING
摘要
Abstract
For a middle temperature curing epoxy resin system and a high temperature curing one, the effect of types and surface chemical characteristics of fiber on the resin curing were studied using differential scanning calo- rimetry (DSC) and infrared spectrometry (IR). The results show that T300 and CCF-1 carbon fiber can accelerate the curing speed of epoxy E-51/2E4MZ resin system, especially at lower heating rate in lower constant temperature. For epoxy E-51/DDS resin system, the increase of the curing speed by the T300 carbon fiber is obvious at lower heating rate in lower constant temperature, while the influence of the CCF-1 carbon fiber on the resin curing can be ignored. This phenomenon results from the different active groups of sizing agent, which are involved in the curing reaction and affect the resin curing. Therefore, the influence of sizing agent in the resin curing should be considered in the composite material curing process.关键词
