In order to study the influences of ZrH₂ onto mechanical properties and damage performances of Al/PTFE， both cylinder and liner specimens of Al/ZrH₂/PTFE， Al/PTFE and pure PTFE were prepared by cold-pressing sintering process. The mechanical properties， impact sensitivity and damage efficiency of the three materials were contrastively studied by the tests of quasi-static compression， drop-weight impact and high-speed target impact. The experimental results showed that all three kinds of PTFE-based materials exhibited elastic-plastic mechanical behaviors and strain hardening effects. Adding a mass fraction of 10% of ZrH₂ into Al/PTFE reactive material improved its yield strength and failure stress to 22.2 MPa and 93.3 MPa， respectively， increased its ignition excitation energy by 1.93 J， and participated in the reaction through activation and decomposition to ensure that its energy release level was not weakened. The two kinds of energetic liners can produce collision energy release reaction and perforation/pore enlargement sympathetic effects during its impacting process， and formed the perforation pattern of petal valgus. Compared with inert damage element， the reactive material greatly improved its hole-enlargement ability by the impact-reaction double damage effect. The introduction of ZrH₂ into Al/PTFE reactive material can further enhance the damage efficiency of the material.
