A kind of bicomponent polyurethane resin was prepared. The fiber reinforced composites were prepared by the continuous glass fiber and bicomponent resin made by half-prepolymer method. The effects of bicomponent resin viscosity-temperature characteristics,mechanical and thermal propertied,molding process on the composites were studied. The results showed that the bicomponent resin had longer pot life and lower viscosity in room temperature. The glass transition temperature of cured resin was 160 ℃. The bend...
