| Abstract: | A kind of high temperature curing epoxy matrix resin was prepared by technologies of prepolymerization, synthesis of b-stage resin and mechanical blending. The effect of quantity of CTBN on the toughness and thermal stability of matrix resin was discussed. The results showed that the epoxy matrix resin prepared by the method of prepolymerization obtained higher heat resistance and toughness, the glass-transition temperature reached 189℃ and the impact resistance reached 26.12 kJ/m^2 when the quantity of CTBN was 5 phr. The prepared matrix resin had better viscosity- temperature property and it could meet the requirement of the forming process and comprehensive properties of epoxy matrix composites. |
