Stab-resistant body armor based on carbon fiber plate splicing block

Abstract

The invention discloses a stab-resistant body armor based on carbon fiber plate splicing blocks. The stab-resistant body armor at least comprises two stab-resistant layers. The stab-resistant layer respectively comprises a plurality of stab-resistant sheets which are made of carbon fiber plates and are formed through CNC processing. Adjacent stab-resistant sheets are fixedly connected through hinges and set screws. Compared with an existing stab-resistant body armor, the stab-resistant body armor is advantaged by good stab-resistant effect and light weight. Raw materials are easy to obtain, a processing process is simple and controllable, and the stab-resistant body armor has good comfort and flexibility, and good damp and hot transmitting performance. The stab-resistant body armor would not bring about physiological fatigue, and market prospect is wide.

Description

technical field [0001] The invention relates to the technical field of protective tools, in particular to a stab-resistant clothing based on splicing blocks of carbon fiber boards. 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" (GA 68-2008) standard,...

AI Technical Summary

Problems solved by technology

Existing stab-resistant clothing can be divided into hard stab-resistant clothing, semi-hard 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
