ABSTRACT:
A FRP laminate composed of synthetic resin material, which contains spheres, and short strands of chopped fibers mixed into the resin/sphere blend in criss-cross, hodge-podge fashion, the sphere members and high application pressure combining to force down any upstanding chopped fibers and to make the chopped fibers lie flat in the resin layer and to knock air out of the resin layer, said sphere members comprising a plurality of high density spheres. A method of making a FRP laminate for a boat hull or the like includes spraying into a mold a synthetic resin liquid containing spheres while simultaneosuly applying chopped glass fibers into the fan-shaped stream of resin/sphere blend with the chopped fibers being randomly distributed in the resin layer in a hodge-podge fashion. The inclusion of the spheres in the resin provides body to the resin itself, so that, with the higher than normal spray pressure being used, there is an impacting force exerted against the glass fibers which forces them into a horizontal, randomly aligned position, thus achieving the end result of a subsequent-to-application rolling process without the need for the rolling process. The forceful application of the resin/sphere blend and the chopped fibers is sufficient to eliminate the trapped air which occurs in normal spray applications of resin and chopped fibers.
