ABSTRACT:
Non-asbestos elastomeric insulation materials for rocket motors are disclosed. The insulation materials comprise 100 parts by weight of a crosslinked elastomer polymer and between about 10 and 100 (preferably 15-75) parts by weight of an organic fiber selected from cotton flock, Sisal and a combination of cotton flock and Sisal. The insulation materials have notable erosion resistance and can be tailored to have thermal, mechanical and other properties of desired character. The organic fiber advantageously functions as a char forming, low density filler. Other ingredients such as silica, phenolic resin, polybutadiene etc. are included to enhance the utility of the insulation materials.
