ABSTRACT:
A method for molding a reinforced composite plastic structure to provide a roughened bondable surface over a portion thereof during the forming operation and which method includes molding a resin-filled, fiberglass-reinforced composite against a mold member having an elastomeric insert in the face thereof such that a portion of the fiberglass fibers are imbedded in the elastomeric member during molding so as to prevent encapsulation of the imbedded fibers by the resin and thereby leaving a roughened or three-dimensional surface over that area of the composite covered by the elastomeric mold inset.
