Abstract
Weight reductions in automobile bumper systems were achieved by means of a three phase program:
- 1.Reduction of bumper reinforcement gauge by use of work hardening renitrogenized steel.
- 2.Reduction of bumper face bar gauge by use of high formability, high yield strength, inclusion shape control steel.
- 3.Design changes to minimize or eliminate bumper reinforcements.
The weight reductions were achieved without reducing the impact strength of the bumper systems.
