In order to study the energy release of gallium-based liquid metal(GLM)-Al-fluoropolymers,GLM-Al with GLM mass friction of 1％,3％,5％,7％was prepared,and GLM-Al-fluoropolymer composite reactive materials were obtained by 3D printing.The microstructure,combustion performance and mechanical properties of GLM-Al and GLM-Al-fluoropolymers were tested by SEM,EDS,XRD,XPS,DSC-TG,high-speed video camera and universal tensile test equipments.The results show that the heat release and the oxidation weight increase of GLM-Al modified with 3％GLM is the largest,which is 6 181 J/g and 42.92％,respectively.Al-fluoropolymers before modification cannot be ignited,but the modified GLM-Al-fluoropolymer can be ignited and can continuour to burn stably,with the maximum burning rate of 6.0mm/s at equivalence ratio of 3.5.and the tensile strength and elongation of GLM-Al-fluoropolymers at break are the largest of 1.73 MPa and 11486％,respectively,which are 1.5 times and 1.3 times higher than that of Al-fluoropolymers before modification.
