Development of a Glass-Fibre Reinforced Polyamide Composite for Rotating Bands
Projectiles are usually provided with an integral rotating band which serves many purposes. These bands are usually made of copper which causes the wear of the gun barrel steel bore. Hence alternative materials are being thought. In the paper, the Polyamide type 66 is proposed as a base material, and its mechanical and tribological properties are modified by different percentages of glass fiber. Experimental results indicate that 2 % GF content as reinforcement to PA66 resin appears to be the ideal compromise.
