Expandable Epoxy Foam: A Systematic Approach to Improve Vehicle Performance

Improving vehicle crash, NVH and metal fatigue performance using expanding polymeric foams can be achieved with a systematic approach. By employing a systematic approach with expandable epoxy foams and alternative carriers, the product development process can be significantly reduced. As a result, high strength and lightweight solutions can be designed to improve the structural performance of today's vehicles.

This technical paper will examine the key steps in utilizing a systematic approach to selecting, designing and modeling structural expandable epoxy foam solutions used in conjunction with metallic and non-metallic carriers. A review of material properties, alternative designs and finite element modeling methods will allow for a thorough understanding of how expandable epoxy foams can meet the demanding challenges for improved occupant safety, reduced interior noise levels and increased durability at a reduced vehicle weight. In addition, a review of the applications for these materials will be discussed to allow for greater insight into how to employ a new generation of structural reinforcing solutions.
