In order to study on the performance of composite explosive charge, composite explosive charge is designed through high detonation velocity explosive and aluminized explosive. The shock wave overpressure of the different charging structures is studied by adopting pressure sensor. The fragment velocity of the different charging structure is studied by target mesh velocity measurement method. Compared with single aluminized explosive performance, the test results show that the composite explosive charging structure, which outer layer is high explosive and inner layer is aluminized explosive, can obviously increase shock wave overpressure and fragment initial velocity
