ABSTRACT:
1. In the process for preparing a rocket motor, the improvement which comprises applying a layer of an uncured organic material capable of being cured to a rubbery material, to the interior combustion chamber wall of a rocket vessel, partially embedding powder grains in the exposed surface of said uncured material before solidification, thereafter curing and solidifying said uncured material, whereby a rubber-base liner is formed having one surface firmly adhering to said wall and said powder grains firmly adhering to the exposed surfaces of said liner, with a portion of each powder grain protruding from said liner, filling the lined portion of the chamber with a thermoplastic propellant charge, and solidifying said propellant charge, whereby a firmly adhering bond is formed between the solidified propellant charge, the powder grains and the solidified liner.
