This paper presents experimentally determined compression sets and compression behaviour of two closed cell, cross linked foam materials; ZOTEK N B50 (Nylon 6) and ZOTEK N A30 (Nylon/Polyolefin alloy). This work forms the basis for future investigations into the post-impact behaviour of these foams. Compression set performance was measured at 25.0, 37.5 and 50.0% strain at nine temperatures ranging from -5 to 90oC. Compression tests at constant strain rates were conducted at four temperatures between 23 to 90oC. Finally compression tests at 23oC were repeated at four strain rates between 0.3 and 550 hr-1 to determine strain rate dependency. The Nagy and Williams-Landel-Ferry scaling factor for strain rate and temperature were applied to the experimental results and equations were derived which allow the performance of the two polyamide based foams to be interpolated over the strain rate and temperature range of study. The required material properties of interest of the base polymers have been assessed and are presented and discussed in relation to the performance of the foam materials.
