Application of Polysulfone Cardo Copolymer in Epoxy Resin Binders for the Production of Carbon Fiber Reinforced Plastics
简介：Carbon-fiber-reinforced plastics(CFRP)with improved mechanical properties based on modified epoxy binders were investigated in this study.By adding 15 parts by weight(p.b.w.)of copolymer of polysulfone with cardo phthalide group(PSFP-70C)to the epoxyanhydride binder,the flexural strength of the epoxy polymer was increased by 60％,the CFRP based on it by 57％,the flexural modulus of the epoxy poly-mer was increased by 83％,and the composite by 96％.The adhesion strength of the binder to carbon fiber reached a high level at 10 p.b.w.of thermoplastic modifier and increased by 65％compared to the unmodified binder.Scanning electron microscopy(SEM)was used to determine that in epoxyanhydride systems with a polysulfone content of 5-15 p.b.w.,the structure belongs to the"matrix dispersion"type and with a con-tent of 20 p.b.w.to the"interpenetrating phase"type.A heterogeneous structure was also observed using dynamic mechanical analysis.展开
