Alternate Floorpan Insulation Materials 931110

Today's cars are creating higher engine temperatures with the increased performance demands of the American public. As a result, interior temperatures in cars are escalating as well. In this study, an attempt was made to find an alternate material for the floorpan insulation. Consideration was given to cost, thermal resistance per area, heat transfer rate, and the contact coefficient for each material. It was also important to remember that the material needed not only stand up to high temperatures, but also could not emit odors that may be offensive to the driver or his passengers. Seven different thermal systems were designed, and tested, as possible alternatives to current shielding systems. The test procedures, along with numerical analysis, helped to determine which of the materials were most suitable for application in today's car.
