Armour splicing-type stab-proof vest based on hollow micro-egg shell structure

Abstract

The invention discloses an armour splicing-type stab-proof vest based on a hollow micro-egg shell structure. The stab-proof vest comprises a plurality of stab-proof sheet sets, each stab-proof sheet set comprises a first stab-proof base plate and a second stab-proof base plate connected with the first stab-proof base plate, the first stab-proof base plate and the second stab-proof base plate are made of a plastic material by means of a 3D printing-laser sintering technology, and the first stab-proof base plate in each stab-proof sheet set is connected with the first stab-proof base plate and the second stab-proof base plate in adjacent stab-proof sheet set. Compared with an existing stab-proof vest, the armour splicing-type stab-proof vest uses an arrangement mode of hierarchical overlapping of animal scales and shells for reference, all the stab-proof base plates are horizontally arranged according to the arrangement of upper-lower layering, overall surface density is reduced, overallcomfort and flexibility are improved, and diathermanous effects and moisture permeability effects are improved; a plurality of hollow semi-ellipsoidal shells are sequentially arranged in a staggeredmanner to effectively disperse the impact force of sword stabbing, and the stab-proof performance of the stab-proof base plates can be enhanced; the stab-proof vest has the advantages of simple production process, high efficiency, light weight, raw materials savings, low cost and good market competitiveness.

Description

technical field [0001] The invention relates to the technical field of personal protection, in particular to a scale spliced ​​anti-stab clothing based on hollow micro-eggshells. Background technique [0002] At present, due to the increasing number of social violent crimes in various forms, the life safety of soldiers, policemen and various special personnel engaged in security work is facing increasingly severe challenges. Due to the strict control of guns and ammunition in China, criminals use knives and daggers as the main criminal equipment. Especially now that sharp knives are relatively easy to obtain, security personnel must always beware of the dangers brought by sharp knives. Therefore, in the process of fighting criminals, security personnel need protective equipment to protect their important parts from sharp objects such as bayonets and daggers. appears to be particularly important. [0003] According to the "Police Anti-stab Clothing" (GA68-2008) standard, po...

Problems solved by technology

[0004] Existing stab-resistant clothing can be divided into hard stab-resistant clothing, semi-rigid and semi-soft stab-resistant clothing, and soft stab-resistant clothing. Among them, the core material of hard stab-resistant clothing is a hard substrate such as metal. Although the stab-resistant performance Excellent, but its weight and rigidity have a great impact on human activities and poor comfort, high process requirements such as lap joints and insert plates, high processing costs, and the weight of this type of stab-resistant clothing is generally heavy, usually greater than 3.5kg; half Hard and semi-soft stab-resistant clothing mainly uses metal and high-performance fibers as composite materials to achieve the purpose of passivating knives. It has better movement flexibility and comfort, but its manufacturing process is complicated, production efficiency is low, and manufacturing cost is high. ;Soft stab-resistant clothing is mainly made of high-performance chemical fiber fabrics such as ultra-high molecular modulus polyethylene fiber as the core material. At present, it is mainly made of multi-layer high-performance fibers, and the thickness usually reaches 40 or 50 layers. It is not flexible to wear. Poor moisture and heat transfer performance, easy to cause physical fatigue, and may cause heatstroke and hyperthermia in severe cases, and there is still a lot of room for improvement in terms of wearing comfort
