Method for rapid production of structural prototype plastic parts

摘要

A method for producing composite, structural plastic prototype parts, having visual and structural characteristics equivalent to those of an actual part to be commercially produced using existing soft tools, including wax, plaster, plastic, spray-metal, and rubber molds ordinarily used for visualization model making, developed using the latest rapid prototyping techniques. Short length fibers reinforcing low viscosity thermoset resins, and in particular resole phenolics, provides a pourable low bulk density polymer compound with minimal externally applied thermal requirements during molding and post cure when required.
