Epoxy Adhesive Exhibiting High Energetic Performance in Deflagration

Abstract:

Reactive structural material (RSM) has been used in modern warheads, binders in which has limitations in achieving high energy release and excellent mechanical properties. Epoxy resins, with their high oxygen content and good mechanical strength, show great potential as alternatives to traditional binders. In this work, two cured epoxy systems with different oxygen contents were prepared and tested under simulated explosion conditions. During detonation, combustion of resin fragments was observed, resulting in a peak blast pressure about 1.7 times higher than that of the bare explosive. Additional dispersion and combustion tests on resin powders confirmed that a higher oxygen content and more C-O bonds led to faster combustion and stronger pressure output. These results suggest that increasing the oxygen-rich structure of epoxy resins can effectively enhance both the combustion behavior and energy release, offering a new approach for developing high-performance binders in reactive materials.
