The Use of Non-Metallic Materials for Projectile Driving Bands. Part 1. The Development of a Shock-Resistant Phenolic Material

Abstract

This report describes the development of a prototype acrylonitrile/ butadiene ("Hycar") modified, nylon cord reinforced, phenolic resin driving band. Bands were moulded from resin-impregnated nylon cord "laid-up", in a pre-form and cured under heat and pressure. The modified resin was produced by incorporating "Hycar" in the phenolic resin by milling, chemical methods of co-condensation being found to be limited in their effectiveness. Firing trials at muzzle velocities of 3000 feet per second showed that all bands were retained in flight. Bands made from a resin containing about 24 per cent of "Hycar" imparted maximum spin and gave reasonable accuracy. Laboratory tests with similar bands showed that they picked up only 3.5 per cent of moisture when immersed in water for 7 months and did not appreciably soften at a temperature of 150-160 deg C.
