Impact resistant component for a vehicle
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.
1. An impact resistant component for a vehicle, comprising:
a support structure comprising a plurality of elongate ridges and a plurality of elongate valleys formed therein, wherein the plurality of elongate valleys are defined between the plurality of elongate ridges and the plurality of elongate ridges are exposed for direct contact with objects, wherein the plurality of elongate ridges defines an undulated surface on the support structure with a predetermined periodicity, wherein the plurality of elongate rides and the plurality of elongate valleys have a period of oscillation that is distinct from the predetermined periodicity of the undulated surface, wherein the undulated surface further comprises raised portions and non-raised portions, wherein the support structure is impact resistant.
2. The impact resistant component of claim 1 , wherein the support structure comprises a fiber-reinforced composite material comprising a polymer and a carbon fiber.
3. The impact resistant component of claim 2 , wherein the fiber-reinforced composite material has a Young's modulus (E) of greater than or equal to about 20 GPa to less than or equal to about 30 GPa.
4. The impact resistant component of claim 3 , wherein each respective elongate ridge comprises a pair of side walls having a height, wherein a ratio of the height of the side walls to the Young's modulus (E) is greater than or equal to about 0.4 mm/GPa to less than or equal to about 1 mm/GPa.
5. The impact resistant component of claim 1 , wherein the raised portions and non-raised portions define a wave pattern.
6. The impact resistant component of claim 5 , wherein the wave pattern is a sinusoidal wave pattern.
