ELASTOMERIC INSULATION FOR SOLID PROPELLANT ROCKET MOTORS,

Abstract

The development of flexible, elastomeric-based, solid propellant rocket motor case insulation is discussed. The effect on insulation properties of type of asbestos, of liquid versus sold elastomers and of methods of dispersing fibrous compounding ingredients, is reported. Oxyacetylene torch and static motor firing test data for some of the better insulation materials developed, and for some commercial materials, are presented. A material with 40% elongation, 1.34 gm/cc density, performance index of 95 sq. cm sec/gm and erosion rate of 2.0 mils/sec was the most promising insulation developed. The material is a 55/45 butadiene/acrylonitrile compound containing phenol furfural resin, asbestos and oxyazoline wetting agent. It was satisfactorily bonded to aluminum and to steel by conventional bonding agent. (Author)
