Puncture-proof and shock-resisting material

Abstract

The invention discloses a puncture-proof and shock-resisting material. The puncture-proof and shock-resisting material comprises at least two layers of lorica structure units and at least one layer of impacting kinetic energy absorbing layer, wherein each impacting kinetic energy absorbing layer is clamped between the two lorica structure units and is bonded to the lorica structure units; each lorica structure unit is formed in a way that multiple layers of shear thickening fluid composite materials are stacked together to form an inner layer, a penetration-resisting high-density flexible coating textile is taken as a coating layer, and the inner layer and the coating layer are sewn by a thread; the impacting kinetic energy absorbing layer is a flexible material layer. The puncture-proof and shock-resisting material provided by the invention has the advantages that the material is flexiable and light, the puncture-proof shock resistance is good, protective property of the material is realized, a stratification phenomenon generated during a using process of the material is effectively prevented, the material can be manufactured into different thicknesses to meet different protective using requirements, and the material can be taken as the material for body safety protecting equipment.

Description

technical field [0001] The invention relates to a safety protection material, in particular to a stab-proof and impact-resistant material. Background technique [0002] Shear thickening fluid is a kind of non-Newtonian fluid, which is slightly viscous under low speed conditions, but under high speed conditions, the apparent viscosity changes greatly and becomes a solid-like substance, and this process is reversible. Its characteristic makes it harden rapidly when it is impacted above a certain speed, and it can return to its original state after the impact is eliminated. The combination of shear thickening fluid and fiber material has good anti-stab and impact resistance properties. Shear thickening fluid composite materials have been widely used in the field of protective materials. [0003] The most common method for making shear-thickening fluid composite materials is to immerse the fabric in a dilution of shear-thickening fluid and alcohol. After the dilution fully ente...

AI Technical Summary

Problems solved by technology

[0004] After a single layer of fabric is impregnated, the anti-stab and impact resistance performance is greatly improved, but it cannot meet the protection requirements, so multi-layer superposition must be used

Simple multi-layer superimposed composite materials will appear delamination during use, which will reduce the protective performance and service life of the material. If the multi-layer materials are directly stitched together, it will be difficult to process due to the characteristics of the material being difficult to penetrate.

In addition, although the simple shear thickening fluid composite material can harden after being impacted, increase the force bearing area, and reduce the impact strength, it lacks an energy buffer absorption layer and has limited impact protection performance.
