ABSTRACT:
A system and method for reducing the occurrence of undesirable deformations (e.g., wrinkling) in a reinforced thermoformable workpiece. The reduction in undesirable deformations is achieved by increasing the buckling resistance of the workpiece by employing a supplemental reinforcing structure. The reinforcement, in combination with a pair of shaping diaphragms, increase the effective buckling resistance applied to the workpiece during the fabrication of a composite product. The method includes forming a workpiece from a plurality of layers of a thermoformable material, and applying to at least one side of the material an external reinforcing structure to form a reinforced workpiece having a top side and a bottom side. At least one of the top or bottom sides of the reinforced workpiece is placed in contact vith a diaphragm, thus forming a shaping assembly. The shaping assembly is then urged into contact with a shaping surface of a work tool to form a composite product, having a shape complementary to the shape of the tool. The composite product is then removed from the tool.
