Abstract
Fluororubber-modified aluminum (AlF) was investigated by core–shell heat transfer model and compared with traditional aluminum with oxide shell (AlO) in terms of heat transfer effect on the reaction behavior of aluminum. Reaction delay behaviors of both AlF and AlO were calculated with diameter ranging from 200 nm to 3.2 µm at different environment temperature. Calculation results showed that AlF got the upper hand over AlO in terms of reaction delay. In the same heat transfer condition, AlF could participate in the reaction with significantly shorter delay time than AlO, which benefits the energy release of the aluminum. Ceiling shell thickness of AlF was determined according to the basic timescale and temperature profile of the explosive reaction zone. Detonation velocity test of AlF was performed with two kinds of AlO as comparisons. Test proved the AlF exhibited higher reactivity than nanoaluminum. Besides, formulation with AlF showed higher detonation velocity than that with AlO, which on the other side verified the reliability of the heat transfer model. Finally, reaction model of AlF in detonation environment was proposed containing three main procedures.
