Abstract
A process uses predictive modeling software for selectively applying relief cuts and tension to the fibers in a 2-dimensional panel prior to shaping the panel into a 3-dimensional part. The predictive modeling software identifies areas of fiber tension in the final molded product, and relief cuts are made in those areas. The plies are loaded into grippers attached to a supporting frame and predictive modeling software is used to identify areas of fiber compression in the final molded product. Tension is applied to the identified areas of fiber compression. The panel is molded in a form and cure press, and the tension is maintained on the material while closing the mold halves. The molded part is able to conform to the final mold shape without tearing in areas of tension and without material buildup in areas of compression in the final molded part or post mold distortion.
