A　ternary　system　of　PTFE/Al/Bi2O3　is　constructed　by　incorporating　PTFE-based　reactive　material　and　thermite　for　enhancing　the　energy　release　of　the　PTFE-based　reactive　material.The　effects　of　Bi2O3　in　the　PTFE/Al/Bi2O3　on　both　mechanical　properties　and　the　energy　release　were　investigated　through　various　tests　such　as　thermogravimetry-differential　scanning　calorimetry,adiabatic　oxygen　bomb　test　and　split　Hopkinson　pressure　bar　test.The　microstructure　observed　through　scanning　electron　microscope　and　X-ray　diffraction　results　are　used　to　analyze　the　ignition　and　reaction　mechanism　of　PTFE/Al/Bi2O3.The　results　indicate　that　the　PTFE/Al/Bi2O3　are　capable　of　triggering　the　exothermic　reaction　of　molten　PTFE/Bi2O3　and　Al/Bi2O3　over　the　PTFE/Al　reactive　materials,thereby　promoting　reactions.The　excessive　aluminum　in　the　ternary　system　is　beneficial　for　increasing　energy　release.The　ignition　of　shock-induced　chemical　reactions　in　PTFE/Al/Bi2O3　is　closely　related　to　the　material　fracture.The　dominant　mechanism　for　hot-spot　generation　under　Split　Hopkinson　Pressure　Bar　test　is　the　frictional　temperature　rise　at　the　microcrack　after　failure.
