Reactive material is a kind of novel impact-initiated energetic material. Understanding the mechanical property of reactive material is an important premise for its application. The tensile and impact properties of polytetrafluorethylene (PTFE)/Al series reactive materials were investigated experimentally using a universal materials testing machine and an improved pendulum impact tester at room temperature. Experimental results show that with the increasing of Al content in PTFE/Al, the tensile strength increases firstly and then decreases. When the Al content is 6%, the tensile strength achieves 36.1 MPa, which is in good agreement with the calculated result. The damage behavior of PTFE/Al is in three steps, including deformation, ductile crack and reaction. With the increasing of Al content, the toughness of PTFE/Al increases firstly, then decreases subsequently. It reaches the maximum of 72.06 J/cm2 when Al content is 40%. At the same condition, the difficulty to reaction is also enhanced and the self-sustaining reaction is suppressed.
