Experimental study on impact-induced reactive material fragments based on fluoropolymers fabricated using alternative methods
conference paper
Reactive materials are a class of energetic material composites that may contain metal and metal oxide powders, fluoropolymers and fillings. These materials release large amounts of energy upon impact, leading to enhanced on-target damage effects. Within this study, composites based on aluminium, bismuth oxide and fluoropolymers were characterized using small-scale sensitivity tests and ignition tests. Subsequent composites were prepared into reactive fragments using pressing, sintering and alternative processing techniques.
Processing methods were explored that have the potential to scale up the production of functional fragments. Testing of the penetration and impact-induced reaction of the resulting fragments were compared against those prepared using conventional methods by firing them with a ballistic gun, using varying velocities and targets, and via explosive projection. The processing method was found to influence the integrity of the pellets during gun firing.
