Abstract
An article manufactured from a polymeric material filled with fibers has an exterior surface having an impact portion with an arcuate configuration to impart impact resistance to the article. The article also includes a plurality of ribs orientated and configured in a unique manner to also impart impact resistance to the article. The ribs extend from the exterior surface of the article. A fillet having a fillet radius interconnects the ribs and the exterior surface. The fibers of the polymeric material are aligned within the article parallel to a flow of the polymeric material when injected into a mold during a molding process. The ribs are oriented in a pattern relative to the fibers to maximize the impact resistance of the article.
