ABSTRACT:
An improved process for the high speed production of structural preforms and molding the preform to produce a product having desired and predetermined fiber directionality and distribution. Continuous strand glass fiber is directly applied to a preform screen along with a resinous binder material. The fiber/binder composite preform is cured. The cured composite preform is transferred to a mold where the composite is injected with a resin and thereafter cured in the mold.
