SOME EFFECTS OF COMPRESSION AND HEAT ON DECELERATOR MATERIALS

Abstract

The degradation of nylon parachute materials and similar materials made from dacron, glass, an organic fiber, and stainless steel was studied at temperatures up to 1000 F, pressures up to 250 psi and times up to 72 hr. The amount of degradation for most of the materials was found to be consistent with that reported by other authors who did not study the influence of pressure. Pressure decreased degradation somewhat because of the reduction in the amount of oxgen contained within the structure. The increased resistance to degradation of Type 700 nylon was apparet in the results. The improved resistance to degradation of dacron as compared to nylon is well known. Glass fabrics retained most of their strength up to 500 F, and the organic fiber up to 600 F (although at 650 F it was badly degraded). Stainless steel showed little change after being exposed to 1000 F for 72 hr. (Author)
