Module 8: Rear Crush Structure


Rear Crush Structure. This module is made from an alloy of aluminum softer than the chassis’s 6061-T6, so that their fail strength is lower than the chassis yield strength. This allows the crush structure to mushroom and then flatten against the chassis, absorbing a tremendous amount of energy, before the chassis even starts to yield. Typically, these are 6063 alloy aluminum but this does vary by aluminum availability in the locality¬†where each¬†are made.

Details: 6″x6″x.125″ thick wall aluminum extruded square tube. 6′ total length.
