Abstract : It is an object of the present invention to provide a method for case bonding a propellant grain directly into a rocket motor tube using a double liner system which will withstand temperature cycling and mechanical vibration and so that they can be reliably fired at temperatures as low as -20F. The objects are accomplished by first coating the inside of a rocket motor chamber or casing with a thermosetting polyurethane composition and then applying a silicone tape to this polyurethane surface. The motor casing is now ready for casting a composite propellant mixture.
