TOUGHNESS EPOXY RESIN WITH HIGH MODULUS FOR CARBON 
FIBER WET FILAMEMT WINDING

Abstract

Abstract:

Highperformance carbon fiber has been widely used in commercial and military fields because of its high strength， light weight and high stiffness.A series of epoxy resins were designed for carbon fiber wet filament winding.Meanwhile the mechanical property and thermal mechanical property of these resins and their carbon fiber composites were analyzed.The effect of resin matrix’s structure and property on the composite was studied based on the analysis.The results show that， for stiffness resins， the modulus of matrix is a key property to gain highperformance carbon fiber composite.With the help of the optimized resin system， the carbon fiber composite possess excellent interfacial properties and heatresistance properties.The tensile strength of T700 CF composite NOL rings is 2480MPa， that of T800 CF composite NOL rings is 2780MPa， and the glass transition temperature (Tg) is higher than 200 ℃.
