Abstract: Provided is a load-carrying or non-load carrying structural component for a vehicle having improved impact resistance, such as a gas tank protection shield, an underbody shield, a structural panel, an interior floor, a floor pan, a roof, an exterior surface, a storage area, a glove box, a console box, a trunk, a trunk floor, a truck bed, and combinations thereof. The component has a support structure with ridges, each spaced apart from one another at predetermined intervals, to form a corrugated surface capable of load-carrying. The ridges are longitudinally extending, raised ridges. The corrugated designs provide support structures that are impact resistant.

Abstract: A method is provided for forming a near-net thermoplastic composite component includes co-spraying a mixture comprising a thermoplastic polymer material and a chopped reinforcing material deposited onto at least one region associated with a tool having a first temperature and defining a near-net component shape. The mixture and adjacent tool is heated to a second temperature while the mixture is on the tool. The first temperature is below the solidification temperature of the thermoplastic polymer material and the second temperature is above the solidification temperature. Then, the mixture is exposed to a negative pressure to promote removal of gases from the mixture and put under compressive force to densify the mixture. The thermoplastic polymer material melts and flows. The tool is cooled to the first temperature and removing the mixture to form the near-net thermoplastic composite component having randomly oriented chopped reinforcement material distributed within a thermoplastic polymer matrix.
