Abstract:
A method of manufacturing a sheet-molded compound (SMC) article having local reinforcement includes the steps of providing a mold for forming the SMC article, filling a portion of the mold with a chopped fiber compound and placing at least one filament-wound reinforcing element in a position in the mold where structural reinforcement of the SMC article is needed. The reinforcing element is formed by winding a resin-coated filament on a mandrel to form coils along a length of the mandrel, where each coil is wound at a predetermined angle relative to an axis of the mandrel. Heat and pressure are applied to the mold to cause the chopped fiber compound to melt such that the melted chopped fiber compound bonds with the reinforcing elements to form the SMC article with local reinforcement. The SMC article with local reinforcement is then removed from the mold.
