Preparation and Performance of Epoxy Resin Cured Compounds with High Mechanical Strength and Energy-release Capability for Reactive Warhead Casings

• • The novel epoxy cured compound TC/BP-CA/PA-F@Al(np) achieves a tensile strength of 72.41 MPa and elongation at break of 4.81%, meeting engineering-grade epoxy requirements for structural applications. • • Incorporation of polyether segments reduces minimum ignition energy by 28.1% compared to TC-CA, and closed bomb peak pressure increases by 3.8%, indicating enhanced ignitability and energy release. • • Addition of fluoropolymer-coated nano-aluminum (F@Al(np)) further boosts peak pressure by 3.2% relative to TC-CA-F@Al(np), demonstrating synergistic energy release enhancement. • • The material exhibits a thermal decomposition onset of ~273 °C and a maximum pressure rise rate of 0.407 MPa·ms⁻¹, with peak pressure reaching 5.935 MPa, confirming rapid and substantial energy release suitable for reactive warhead casings.
