摘　　要：利用慢速烤燃试验和冲击波感度试验研究了FOX-7与RDX不同混合比例对炸药响应特性的影响。试验表明:当FOX-7的混入量(质量分数)低于72%时,炸药在慢速烤燃试验中的响应剧烈程度表现为爆轰反应,其临界起爆压力接近6.62 GPa;当FOX-7的混入量(质量分数)等于72%时,炸药在慢速烤燃试验中的响应剧烈程度由爆轰降至爆燃,其临界起爆压力升至7.27 GPa;当配方中完全采用FOX-7时,炸药在慢速烤燃试验中的响应剧烈程度由爆燃降至燃烧,临界起爆压力升至8.24 GPa。造成上述试验结果的原因可能是压装炸药在成型过程中因颗粒的破碎、重排作用使FOX-7对RDX形成包覆,进而改善了RDX材料点火增长速度快的本质特点。Response properties of pressed explosive with different mixture ratio of FOX-7 and RDX were studied by small-scale cook-off bomb test and shock wave sensitivity test.Slow cook-off test shows detonation when the addition content of FOX-7 in the formula is less than 72%,and the critical initiation pressure is close to 6.62 GPa.When the addition content of FOX-7 reaches 72%,the slow cook-off response of the explosive transits from detonation to deflagration,and the critical initiation pressure increases to 7.27 GPa.When the addition content of FOX-7 was reached 100%,the slow baking response of the explosive degrades from deflagration to combustion,and the critical initiation pressure increases to 8.24 GPa.The reason for the test results above might be that FOX-7 was coated RDX because of particle breakage and rearrangement during the molding process,which improve the essential characteristics of rapid ignition growth of RDX materials.
