Slapper energy change element structure and preparation method thereof

Abstract

The invention discloses a slapper energy change element structure and a preparation method thereof. The slapper energy change element structure comprises a shear layer, a fly layer, an explosive foil and a substrate, wherein the shear layer, the fly layer, the explosive foil and the substrate are laminated and bonded in sequence from top to bottom; a plurality of conductive through holes are formed in the substrate in a penetrating manner; the hole surfaces of the upper ends of the conductive through holes are in contact with the lower surface of the explosive foil; the hole surfaces of the lower ends of the conductive through holes are flush with the lower surface of the substrate; a shear through hole is formed in the center of the shear layer in a penetrating manner; the upper hole surface of the shear through hole is flush with the upper surface of the shear layer; the lower hole surface of the shear through hole is in contact with the upper surface of the fly layer; and the fly layer is made of a polyimide material. By lamination and bonding of the shear layer, the fly layer, the explosive foil and the substrate in sequence from top to bottom, contact of the molecular layers of the substrate, the explosive foil and the fly layer is realized, and transverse diffusion of plasmas is prevented, so that the energy conversion efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of pyrotechnics, in particular to a structure of a shock plate transducer element and a preparation method thereof. Background technique [0002] The shock transducer is the key component of the shock detonator. When the strong current in the shock detonator passes through the shock transducer, the shock transducer will melt, vaporize and ionize under the action of the instantaneous high current, forming The high-temperature and high-pressure plasma drives high-speed motion and hits the explosive to be detonated to complete the detonation. There are many gaps in the traditional impact plate transducer, which will cause the formation of high-temperature and high-pressure plasma to easily diffuse, which affects the sensitivity and accuracy of detonation. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the object of the present invention is to provide a shock plate transducer ...
