Abstract
The present invention is a highly predictable composite usable to fabricate such structural articles as complex-shaped automotive body parts and building panels. Included in this composite is at least one netlike preform having a plurality of inter-crossed roving bound to each other at thermoset junction points. This preform is compressed into a mold, and at least one layer of polymer paste is added thereto. The preform layers and the polymer paste layers are compressed to the shape of the mold, and then they are heat and flame treated to complete the curing of the thermoset resin and to produce a desired surface finish.
