  • Patent number: 4340562
    Abstract: This invention concerns a process for fabricating fiber reinforced thermoset resin articles. The process comprises the steps of (a) providing in a distributing zone, an intimate mixture of one or more fibers with a melting point or a glass transition temperature above about 130.degree. C. and a fiber length greater than about 0.5 centimeters, and a liquid resin, said resin having a viscosity of less than about 3000 centipoise at 25.degree. C., (b) injecting said mixture into the cavity of a closed matched metal die mold, thereby filling said cavity with said mixture, (c) heating said mixture so as to cause an exothermic reaction to occur in said mold, and (d) opening said mold and recovering a thermoset fiber reinforced molded article therefrom.
