Truck Cap and Method of Making a Truck Cap Using a Closed-Cavity Bag Molding Process

A truck cap and a closed-cavity bag molding process of making a truck cap. The truck cap includes a composite base and a composite top coupled to the composite base. The composite top has a reinforcement positioned between first and second layers of fiber mats. A closed-cavity bag molding process of making a truck cap includes placing a first layer of fiber mat into a mold cavity, applying a bleeder strip around an edge of the mat and periphery of the mold, placing a reinforcement into a roof portion of the mold, placing a second layer of fiber mat into the mold cavity over the first layer and reinforcement layer, providing a flexible cover over the layers of fiber mat, actuating a vacuum to remove most of the air between the cover and mold, and delivering resin to the layers of fiber mat and reinforcement.
