摘要：A toughened epoxy resin matrix is designed for the wet-winding of a carbon fiber composite solid rocket motor case, under the consideration of the relations among viscosity, mechanical and heat-resistance properties. The curing kinetic parameter, gel time and properties of casting parts and carbon fiber composite are studied by means of DSC, FT-IR, etc. The results show that the toughened epoxy resin matrix has advantages of low viscosity, longer-life-time and higher toughness, the matrix has strong interfacial adhesion with the carbon fiber, and the strength conversion ratio of the carbon fiber of the composite motor case made is high.
