ABSTRACT
Various foam candidates were subjected to a series of quasi-static lab tests in compression, along with standard FQC tests on energy absorption.
2.1. Materials
A variety of closed-celled PE foams were selected to examine the effect of foam density and crosslinking. The former influences deformation properties significantly, while the latter could influence elevated temperature response. In addition, an ethylene-based crosslinked elastomer foam, along with a PU and an SBR shockpad were included. Samples are described in Table 1. Specimens were labeled based on polymer type, foam density provided by the supplier (kg/m3) and thickness (mm). In brackets, the foam type is specified as “x” for crosslinked, “p” for plastomeric and “e” for elastomeric.
