Abstract:

The primary objective of this study was to determine the variability in the dynamic cushioning properties of flexible polyurethane foam materials procured from different sources under the requirements of MIL-P-0026514C. A secondary objective was to establish the degree of correlation between the dynamic cushioning properties of polyurethane foam and various material physical properties such as density, static stress characteristics and Indent Load Deflection ILD factor. The results of this study show that there is considerable variability in the dynamic cushioning properties of polyurethane foam materials. There appears to be some correlation between dynamic cushioning characteristics and material properties such as ILD, average stress, and static energy absorption, but no correlation with density.
