<p>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 an FRP laminate for a boat hull or the like includes spraying into a mold a synthetic resin liquid containing spheres while simultaneously 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. An apparatus for molding FRP laminate includes a spray gun, a high pressure spray pump (13) upstream of the spray gun, a fluid transfer pump (15) upstream of said spray pump, and an accumulator (17) between the high pressure pump and the spray gun to eliminate pulsing which otherwise occurs when the spray pump reverses the direction of its stroke, whereby the high viscosity resin is properly fed from its storage container (19) to the spray gun and a smooth steady spray is obtained.</p> |
