A method of producing a reinforced carpet roll grain propellant by the steps including placing a reinforcement material such as fiberglass between sheets of plastic, inserting these three layers into spaced apart rollers, placing the desired propellant composition onto the reinforced material, and then feeding the layers of plastic and reinforced material with the propellant thereon through said rollers to produce a carpet roll that has a predetermined thickness of propellant on opposite sides of the reinforced material. By this method, a propellant is made that is reinforced and flexible so that it can be rolled into a carpet roll.
