Expanded Polypropylene Foam Applied to Intercept Objects/Liquids, During a Crash Situation 2004-01-1711
This paper describes an approach to the application of Expanded Polypropylene (EPP) molded foam to absorb impact energy inside the passenger cabin, through the design of an EPP Energy Absorber Pad, located between the engine and the passengers cabin. This pad shall increase safety for passengers in case of collision, as well as improve the insulation of the engine noise. The main function for this pad is to avoid any small metal, plastic objects or engine fluids (gasoline, oil or water) to enter into the cabin from the engine compartment, during a collision. The EPP foam pad closed cell structure intercepts liquids and solid pieces that may pass through the metal bodywork, and may be cause of physical injury for passengers.
