IMPACT OF ACCELERATOR CONTENT ON EPOXY RESIN FOR CARBON FIBER COMPOSITES BY VACUUM INFUSION MOULDING PROCESS

Abstract

Abstract: Impacts of accelerator content on epoxy resin were studied systematically by rheometer and DSC analysis for carbon fiber composites in large structural applications by vacuum infusion moulding process. The viscosity behavior, process window, curing characteristics and elemental mechanical properties were analyzed for this epoxy resin with different accelerator content of 0.5%, 1.0%, 1.5%. The optimal infusion temperature didn't change any as the accelerator content increases, but the pot life was obviously shortened. The temperature and time required for complete curing decreased with the increasing of accelerator content. The mechanical properties are almost not affected. Thus, this epoxy resin can be used in ordinary mould.

Key words: epoxy resin, rheological behavior, carbon fiber, vacuum infusion, processing window
