Resin-infused short fiber composite materials

Abstract:

Systems and methods are provided for fabrication of short-fiber composites. One embodiment is a method for forming a short-fiber composite. The method includes forming a bed of randomly oriented dry fibers on a base, drawing resin into the bed in response to pressure to form a mixture of randomly oriented fibers impregnated with thermoset resin, perturbing the mixture while preserving fiber length at the mixture and degassing the mixture, and extruding the mixture to form a preform.
