Abstract
A vehicle bumper assembly includes an adaptive energy absorption module operatively connected to a vehicle bumper body. The adaptive energy absorption module includes a primary deformable impact absorber member defining a primary impact chamber having a shape that is structurally adaptive or otherwise conforms to an impact force received by the bumper body. A secondary deformable impact absorber member is arranged in the primary impact chamber and defines a secondary impact chamber containing a shear thickening fluid that exhibits a decreasing viscosity responsive to the impact force. A plurality of fluidically connected tertiary deformable impact absorber members are arranged in an array the primary impact chamber and defines a plurality of tertiary impact chambers containing a volume of fluid, and has a shape that is structurally adaptive to the impact force.
