N2 - In recent years, PTFE/Al-based reactive materials with high energy density have attracted wide concern, but the low energy release efficiency restricts further application. In this paper, molybdenum trioxide (MoO3) was introduced into PTFE/Al to control the mechanical response and the energy release performance. With the MoO3 content increasing, the material properties gradually change from elastic-plastic to brittle. The ballistic impact experiments are conducted to analyze the overpressure characteristics of PTFE/Al/MoO3. The experimental results showed that the content of MoO3 has significant influence on the energy release behaviors of PTFE/Al-based reactive materials. With the MoO3 content increasing from 10% to 40%, the quasi-static overpressure peak and impulse decrease from 0.147 MPa to 0.105 MPa, and from 9.184 s·kPa to 5.914 s·kPa, respectively. The mechanism analysis showed that, because of Al/MoO3 reaction characteristics, the additional MoO3 affect the shock wave and impact sensitivity of PTFE/Al/MoO3. The study had constructive significance for the application of oxides to promote the energy release performance of PTFE/Al reactive materials.
