Effect of Composition, Density, and Environment on the Ablative Performance of Phenolic Nylon.

Abstract

Ablative materials are commonly used to protect spacecraft from the thermal environment which is encountered when entering planetary atmospheres. Materials which char when heated provide the best protection in many cases. Many char-forming materials have been formulated and tested; a mixture of phenolic resin and nylon is representative of the best performing of these ablative materials. Good thermal-protection performance has been demonstrated for a mixture of 25 percent powdered phenolic resin, 50 percent powdered nylon, and 25 percent phenolic Microballoons, molded to a density of 36 lbm/cu ft (580 kg/cu meters). (Percentages are based on weight.) p3
