Influence mechanism of impact pressure on energy release behavior of high-energy insensitive particle reinforced composites

Abstract The effect of impact pressure on energy release behavior of high-energy insensitive particle reinforced composites is investigated. The results show that as the impact pressure reaches 5.39 GPa, the high-energy insensitive particulate reinforced composites initiation occurs for the first time. With the increase of the impact pressure, the gas pressure inside the high-pressure explosion chamber increases gradually until the impact pressure increases to 11.95 GPa. The quantitative relationship between impact pressure and energy release behavior is established.
