端羟基聚叠氮缩水甘油醚与六硝基六氮杂异伍兹烷基四元混合炸药能量释放研究

CL-20 is one kind of high energy explosive with wide application prospect. The explosion energy of GAP/CL-20/oxidant/combustible agent quaternary system explosive is calculated to study its potential energy. The calculated results show that lithium perchlorate can be used significantly to improve the explosion heat, but the use of it in the cast explosive needs the further research on its modification. The samples of GAP/CL-20/AP/Al explosive were prepared, and the test method of underwater explosion was used to test and estimate its underwater explosion energy. The test results show that the energy density of the quaternary explosive can achieve the maximun with a CL-20 content of 15-20 wt%, and the explosion heat of CL-20 based GAP cast explosive can achieve the maximum when the Al/O is between 0.51-0.71 with a CL-20 content of 20wt%. According to the test data, the estimated energy density of the explosive can be up to 2.88 times of TNT equivalent.
