Abstract

A rocket motor or other gas generator the case of which is ventable at a predetermined temperature substantially greater than the ambient temperature range for storage and operation thereof and substantially less than the auto-ignition temperature of gas generant material contained therein so as to prevent catastrophic propulsion or burst in case of fire. In order to provide such venting without requiring any shaped charges or other auxiliary system for that purpose at all, the case is composed of a matrix-impregnated fibrous material wherein the fibrous material is characterized by having a melting point which is substantially higher than the ambient temperature range and which is substantially lower than the auto-ignition temperature of the gas generant material. The matrix material is preferably actinic radiation-curable at a temperature which is substantially lower than the melting point temperature of the fibrous material. The case may preferably be composed of polyolefin fibrous material impregnated with an ultraviolet light-curable radiation.
