Active Reactive Energetic Material Sandwich Cylinder Anti-knock Structure

Abstract

The invention discloses an active-response type sandwich cylinder anti-explosion structure of energetic materials, aiming to solve the problems of insufficient active anti-explosion ability of the traditional sandwich cylinder explosion-proof structure. The invention consists of an outer cylinder, a composite core, an inner cylinder and a bottom end cover. The inner cylinder, the composite core, and the outer cylinder are coaxially assembled from inside to outside to form a sandwich structure, and the bottom end cover is welded to the lower end surface of the composite core. The composite core is composed of an outer reaction core layer, a middle fiber core layer and an inner high polymer core layer. The outer reaction core layer is energetic material, the middle fiber core layer is high-strength carbon fiber or glass fiber, and the inner high polymer core layer is elastic high polymer material. The inner cylinder consists of a cylinder shell and foam pads. The bottom end cap is composed of barrel bottom, ring, bottom core and cover plate. The bottom core material is an energetic material. The invention can enhance the active anti-explosion ability of the anti-explosion structure and the active dredging ability of explosion energy, improve the protection performance of the anti-explosion structure, and solve the problem of poor controllability of the explosion energy output direction.

Description

technical field [0001] The invention belongs to an anti-explosion structure, in particular to an anti-explosion structure of an active-response energetic material sandwich cylinder. Background technique [0002] Blast shock protection is extremely important in both military and civilian applications. Anti-blast structures have been widely used in scientific research, national defense and military, explosive processing, public safety and other fields. [0003] The sandwich structure has the advantages of shock absorption and impact energy absorption, and has attracted widespread attention in the field of explosion protection. Research on sandwich structures of lightweight materials such as foam and polymers has been widely carried out at home and abroad. The traditional explosion-proof tank structure mainly resists the attack of explosion shock waves and fragments through the side wall and bottom of the cylinder, protects the safety of surrounding equipment and personnel, an...
