Abstract: In order to reduce the firing energy of the exploding foil blasting machine and optimised its performance, the Al/Cu exploding foil transducer element was fabricated by micro-electro-mechanical system (MEMS) technology, and its electric explosion performance and ability to drive the flyer were studied. The results showed that when the charging voltage was 1.3 KV, the energy utilisation rate of the Al/Cu exploding foil was increased by 25% compared with the traditional Cu exploding foil. Compared with the traditional Cu explosive foil initiator, the Al/Cu explosive foil initiator driven flyer speed is faster and the ignition sensitivity is higher.
