ABSTRACT:
A cured resin and fiber part generally can be manufactured by providing a mold that defines a cavity having at least one shape-defining surface. An in-mold paint sheet having a bonding side and a finish side can be positioned in the cavity of the mold such that the finish side of the in-mold paint sheet is positioned adjacent to the shape-defining surface of the mold. A mixture of a thermoset resin and a plurality of reinforcing fibers are then introduced into the cavity of the mold such that the resin and fiber mixture contacts the bonding side of the in-mold paint sheet. The in-mold paint sheet and resin and fiber mixture are then compressed in the mold while being heated causing the resin and fiber mixture to be cured and bonded to the in-mold paint sheet resulting in a part having the finish side of the in-mold paint sheet as a finished surface of the part.
