【Abstract】 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, ect . The results showed that the formulation of the toughened epoxy resin matrix has 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 is high.更多还原
