Abstract
A mechanical method of case bonding a solid propellant to a rocket motor e wherein a coating of a liner material is first applied to the internal surface of a rocket motor case. While the liner material is uncured a mechanical structural material selected from wire grid, wire hooks, rubber spikes, steel wool, metal grid, polyamide material, or polypropylene material is embedded in the liner material but allowed to protrude above the liner material. The liner material is allowed to cure, and an uncured propellant composition is cast against the cured liner and allowed to flow around the protruding mechanical structural material. On curing, the propellant composition attaches itself to both the liner and the mechanical structural material. The combination of the liner material, the mechanical reinforcing material, and the propellant composition provides a mechanical reinforcement in the propellant which is held in place with improved tensile adhesion against the rocket motor case wall.
