Abstract

The invention provides a gradient type concave honeycomb explosion-proof structure. The gradient type concave honeycomb explosion-proof structure comprises a surface plate, a gradient type negative Poisson's ratio structure layer and a back plate, wherein the gradient type negative Poisson's ratio structure layer is arranged between the surface plate and the back plate. According to the invention, the surface plate and the back plate are coupled with the gradient type negative Poisson's ratio structure, and the structural integrity and strength can be improved; compared with a common single-layer negative Poisson's ratio structure, the gradient type negative Poisson's ratio structure is higher in impact resistance, has the characteristics of low surface density, high impact strength, high anti-explosion performance and good energy absorption and shock absorption performance; and the gradient type concave honeycomb explosion-proof structure has wide application prospects in the aspects of explosion prevention, emergency rescue protection, light armor and the like.

Description

technical field [0001] The invention relates to the technical field of explosion-proof structures, in particular to a gradient type concave honeycomb explosion-proof structure. Background technique [0002] Existing explosion-proof equipment has a large mass, up to 30-50Kg, poor wearability, and heat and moisture resistance is 5-6 times that of down jackets, which seriously threatens the life safety of rescuers and reduces rescue efficiency. In recent decades, researchers at home and abroad have conducted a lot of research on lightweight explosion-proof structures and their protective performance, focusing on the balance between the protective performance and wearability of individual explosion-proof equipment, and proposed new lightweight explosion-proof materials and structures. higher requirement. [0003] At present, the common explosion-proof structure has high density, high cost, long processing cycle, and is limited by complex models. The personal protective equipme...
