Abstract
A method of making a resilient composite structure having an exposed reinforcing fabric layer free of structural foam and curable resin and for manufacturing a composite article utilizing the resilient composite structure. The method for manufacturing a composite article includes the steps of positioning at an attachment point within the first plastic shell a resilient foam core composite structure having an exposed reinforcing fabric layer attached to a non-woven fabric layer on one side thereof, the resilient foam core substantially filling interstices of the non-woven fabric layer, without substantially penetrating the reinforcing fabric layer; saturating said reinforcing fabric layer with a curable plastic resin; positioning said second plastic shell on said first plastic shell so that said resilient composite structure contacts an attachment point of said second plastic shell and is compressed between the plastic shells; and allowing said plastic resin to cure.
