The automobile industry is seeing an increased need for the application of plastics and their derivatives in various forms such as fiber reinforced plastics, in the design and manufacture of various automotive structural components, to reduce weight, cost and improve fuel efficiency. A lot of effort is being directed at the development of structural plastics, to meet specific automotive requirements such as stiffness, safety management, strength, durability, environmental standards and recyclability. This paper presents the effect of foam filling on the energy absorption during impact, of typical automotive body sections made up of fiber reinforced thermoplastic material with or without metallic reinforcements. In particular the study compares energy absorption characteristics during impact of typical automotive sections made of fiber reinforced thermoplastic materials without foam filling, with foam filling, with foam and some light metallic reinforcements. An attempt is also made to present results on such energy absorption at varying temperature conditions such as low temperature, ambient and elevated temperatures. In all cases it is found that the inclusion of foam and some lightweight material reinforcement enhances not only the structural integrity of fiber reinforced plastic sections but also improves significantly the energy absorption of such material systems under impact.
