Carbon Foam Bumper Applications

CFOAM® Carbon Foam, because of its unique combination of high compressive strength and considerable impact absorption capacity, is an attractive material for enhanced performance bumper systems.

Car bumpers generally consist of a tough plastic cover and underneath, a reinforcement framework made of steel, aluminum, fiberglass composite, or plastic.

To be effective, bumper systems also should include mechanisms that compress to absorb crash energy — polypropylene foam, plastic honeycomb, or other materials, and be designed with an appropriate distance between the reinforcement bar and the structure that it is to protect.

CFOAM carbon foam’s cellular structure can be tailored by adjusting the cell wall thickness and pore size along one axis, resulting in a variable crush strength vs. penetration depth.

Shown here is a concept for a bumper system crush capsule made up of CFOAM carbon foam with an axial guide hole, wrapped in a high strength polymer composite sheet material. The capsules are placed in specially designed cylinder/plunger mechanisms which connect the bumper system to the protected structure.

CFOAM carbon foam is expected to play an important role in energy absorption for automobiles, trucks, and race cars.
