Active reaction type energetic material sandwich cylinder anti-explosion structure

Abstract

The invention discloses an active reaction type energetic material sandwich cylinder anti-explosion structure. The problems that a traditional sandwich cylinder anti-explosion structure is insufficient in active anti-explosion capacity and the like are solved. The active reaction type energetic material sandwich cylinder anti-explosion structure is composed of an outer cylinder, a composite core body, an inner cylinder and a bottom end cover; the inner cylinder, the composite core body and the outer cylinder are coaxially assembled into a sandwich structure from inside to outside, and the bottom end cover is welded to the lower end face of the composite core body; the composite core body 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 made of an energetic material, the middle fiber core layer is made of high-strength carbon fibers or glass fibers, and the inner high polymer core layer is made of an elastic high polymer material; the inner cylinder is composed of a cylinder shell and a foam cushion block; the bottom end cover is composed of a barrel bottom, a circular ring, a bottom core and a cover plate; and the material of the bottom core is an energetic material. The active anti-explosion capability of the anti-explosion structure and the active dredging capability of explosion energy can be enhanced, the protection performance of the anti-explosion structure is improved, and the problem that the controllability of the output direction of the explosion energy is poor is solved.

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...
