To address the issue that the resin matrix of carbon fiber composites cannot participate in explosive energy release when used in warhead casings， a new type of epoxy resin curing compound with both high mechanical properties and high energy release characteristics was developed by introducing more thermally decomposable polyether segments and more easily combustible fluoropolymer-coated nano-aluminum powder into a high-rigidity epoxy resin. The curing compound was characterized by methods such as infrared spectroscopy， quasi-static mechanical testing， TG-DSC coupled testing， laser ignition testing， and closed vessel burst tests to investigate its crosslinked network structure， mechanical properties， thermal decomposition characteristics， ignition and combustion properties， and energy release characteristics. Results show that the modified epoxy exhibits a well-developed crosslinked network， with a tensile strength of 72.41 MPa and an initial decomposition temperature of approximately 273 ℃. The minimum ignition energy is reduced to 1.77 J. In addition， closed bomb tests reveal a maximum pressurization rate of 0.407 MPa·ms^-1 and a peak pressure of 5.935 MPa， indicating significantly enhanced energy-release performance.
