Abstract: In order to study the effect of fluororubber mass fraction on ignition and combustion performance of nAl@fluororubber reactive material, nAl@fluororubber reactive material with different mass fractions of fluororubber was designed and prepared in this paper. The combustion characteristics and dynamic ignition behavior of the material were studied by constant volume combustion tests, self-propagating combustion tests and dynamic loading ignition tests. The influence of the mass fraction of fluororubber on the maximum pressure, pressurization rate and burning speed during combustion was analyzed. The dynamic ignition threshold for nAl@fluororubber reactive material was obtained, and the dynamic ignition mechanism of nAl@fluororubber reactive material was revealed. The results show that the combustion pressure peak increased about 27 times, and the pressurization rate increased about 832 times, with the increase of fluororubber mass fraction from 10% to 25%. While the fluororubber mass fraction was less than 15%, the material couldn’t self-propagate and burn. Compared to nAl@15%fluororubber reactive material, the burning speed of nAl@25%fluororubber reactive material increased by 5.6 times. The combustion performance was improved due to the high mass fraction of fluororubber and excellent interface contact for materials. In addition, the dynamic loading ignition results showed that ignition threshold of nAl@fluororubber reactive material decreased by 37.5%, with the mass fraction of fluororubber increasing from 20% to 25%. nAl@25%fluororubber reactive material was ignited, when the absorption energy was 8 J.
