Reinforced body in white and reinforcement therefor
A structural body of a vehicle comprises: a hollow component comprising walls that define a channel, wherein the component has a component length, and wherein the component is selected from the group consisting of beam, rail ( 58 ), pillar ( 50,52,54,5 ), chassis, floor rocker ( 60 ), and cross-bar, or combinations comprising at least one of the foregoing; and a plastic-metal hybrid reinforcement ( 1 ) having cavities therethrough ( 14 ), and a support ( 6 ) having greater than or equal to 3 walls forming a support channel. The plastic element ( 4 ) is located in the support channel ( 6 ) wherein the reinforcement ( 1 ) is located in the component channel.
