In this study, the influence of various mass ratio of tungsten (W) and composite porosity upon the reaction efficiency of fluoropolymer‐matrix reactive materials (RMs) under different impact velocities was investigated. A series of ballistic experiments were carried out by using a quasi‐sealed test chamber to study the impact‐initiated characteristics and energy release behavior of RMs. The impact response process were calculated by using the Wu‐Jing equation of state (EOS) and the n‐dimensional nuclear growth model. The accuracy of the theoretical model was verified with the experimental results, which was used to analyze the influence factors of the reaction efficiency. The theoretical calculations can accurately predict the reaction results of RMs, increasing the impact velocity is the most effective way to improve the reaction efficiency of RMs. In certain impact speed, the reaction efficiency is determined by the combined effect of the tungsten content and the initial porosity of the composite.
