Expandable epoxy foam: A systematic approach to improve vehicle performance

摘要

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 modelling structural expandable epoxy foam solutions used in conjunction with metallic and nonmetallic carriers. A review of material properties, alternative designs and finite element modelling 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.
