Abstract:
1. A hood assembly for use with a vehicle, comprising: an upper layer having a first interface surface; a first lower layer having a second interface surface; a first middle panel having substantially opposing first and second surfaces defining a first corrugated profile having a first and a second plurality of bonding surfaces; wherein said first plurality of bonding surfaces is operatively attached to said first interface surface and said second plurality of bonding surfaces is operatively attached to said second interface surface to thereby define a first plurality of channels oriented laterally with respect to said vehicle; wherein said first corrugated profile defines a first height and a first wavelength along a first region of the hood assembly, said first height and wavelength each being configured to provide a first predetermined level of absorption and attenuation of kinetic energy imparted to the hood assembly by objects upon impact therebetween; and wherein said first corrugated profile further defines a second height and a second wavelength along a second region of the hood assembly, said second height and wavelength each being configured to provide a second predetermined level of absorption and attenuation of kinetic energy imparted to the hood assembly by objects upon impact therebetween.
