US12276486 - Method for producing a warhead component

A method is provided for producing a warhead component including an inner shell. The method includes arranging a first casing of a thermoplastic to enclose the inner shell, arranging pre-formed projectiles between the first casing of thermoplastic and the inner shell, and heat-treating the first casing so that the first casing shrinks and fixes the pre-formed projectiles to the inner shell. A warhead, a projectile, and a bomb are also provided.
