The dynamic compressive and reactive properties of two kinds of PTFE/Al reactive materials were studied by the split Hopkinson pressure bars (SHPB). The effects of Al content on yield stress, fragmented and reactive properties of PTFE/Al reactive materials were analyzed. Results show that PTFE/Al is sensitive to the strain rate. In the strain rate range of 1000-8000 s^-1, the yield stress of PA265 is 32-44 MPa and the yield stress of PA35 is 40-55 MPa; the yield stress increases with Al content; the fragmented stress is 143-153 MPa in the strain rate range of 3100-5800 s^-1 for the PTFE/Al reactive materials; the critical reactive stresses of PA265 and PA35 are 157 MPa and 163 MPa; partial reaction phenomena appear frequently due to lacking of enough oxidant polytetrafluorethylene (PTFE), if Al content is higher than 35%.
