Process and apparatus for the rapid and repetitive manufacture of fiber reinforced thermoset resin articles having uniform mechanical properties. The process comprises the steps of (a) providing one or more fibers with a melting point or a glass transition temperature above about 130 DEG C in the form of an interlocked mass in a heatable matched metal die mold (11, 13), (b) providing in an accumulator zone (15, 35), a liquid body of a thermosettable organic material having a viscosity determined at 120 DEG C, in the absence of curing agent therefor, of less than about 50 centipoise, and which is curable upon heating to a thermoset resin composition, the viscosity of said liquid body being maintained essentially constant in the accumulator zone (15, 35) by keeping its temperature below that at which curing of said material is substantial, (c) closing the mold containing the web, (d) injecting at least a portion of said thermosettable organic material under pressure from said accumulator zone into the mold to thereby fill the cavity in said mold, (e) initiating the curing of said material in said mold by subjecting the material to a temperature above the temperature at which the curing of said material is initiated, by heating (12) the mold, and (f) opening said mold and removing the cured thermoset article therefrom. |
