摘要：
Carbon-based energetic composite (CEC) was prepared by mixing the carbon fibers with lead azide (LA), lead styphanate (LS) and nickel hydrazine azide (NHA), respectively. The relationship between carbon fiber content and igniter performance was studied. The experimental result indicates that the ignition voltage of igniter is the lowest when the carbon fiber content is 30%. The 50% ignition voltages of NHA-CEC igniter, LS-CEC igniter and LA-CEC igniter are 14.1 V, 17.6 V and 27.8 V, and their safety currents are 280 mA, 250 mA and 180 mA,respectively. The 50% electrostatic ignition voltages of NHA-CEC igniter, LS-CEC igniter and LA-CEC igniter are 28.9 kV, 27.3 kV and 30 kV, respectively, in pin-to-pin, and the antistatic capacity is more than 25 kV in pin-to-case of three type of igniters. The ignition process of igniter was investigated by high-speed photography and lead plate test of detonator. The results show that all the ignitors have reliable ignition ability, and LA-CEC and NHA-CEC can reliably detonate RDX to perforate the lead plate. The bridgeless pyrotechnics with CEC show more anti-electrostatic ability and are fabricated easily to the bridge wire and semiconductor bridge pyrotechnics. © 2019, Editorial Board of Acta Armamentarii.
