PHOSPHORUS FILLING FOR MUNITIONS

Abstract

In a continuation of the search for suitable binders for granulated white P in fillings for munitions, several additional commercial casting resins were tested. A( TEST FOR EVALUATION OF THE THERMAL STABILITY OF THE EXPERIMENTAL FILLINGS IN PROJECTILES WAS DEVISED AND USED. The method is based on the lateral shift of the center of gravity from the longitudinal axis of the filled projectile when the projectile is stored on its side at 65 C. Of the experimental phosphorus fillings subjected to firing tests, those in which the granulated phosphorus was bound with plaster of Paris were the most promising. Fillings bound with Duraton, Palestic, and Thiokol LP-2 performed fairly well, but fillings bound with phenolic casting resins gave poor smoke screens. Flame retardants, such as are used in permissible explosives to lower the temperature of combustion, appeared in preliminary tests to be worthy of further study as agents for improving the performance of the phosphorus fillings.
