Problems solved by technology

During the Second World War, the bulletproof helmets used by countries around the world were mainly made of high manganese steel or special steel stamping. The metal bulletproof helmet has the disadvantages of heavy weight, unstable bulletproof performance, high electrical conductivity, low heat insulation performance, and secondary rebound of projectiles. other serious problems
Due to the low modulus of thermoplastic resin and the strong high-temperature creep performance of ultra-high molecular weight polyethylene fibers, the single-material bulletproof helmet has low hardness, poor stiffness, weak temperature resistance and convex back after the projectile penetrates. large and many other issues
Moreover, with the development of science and technology, a large number of modern weapons have been equipped with soldiers, and functions such as infrared tracking and detection, GPS positioning, and infrared thermal sensing have become necessary functions for high-tech weapons, and non-metal composite bulletproof helmets are currently the only single protection. Functions have become stretched, gradually unable to adapt to the modern battlefield environment where electronic information technology is ubiquitous

Abstract

The invention relates to a multifunctional composite material bullet-proof helmet and a manufacturing method of the multifunctional composite material bullet-proof helmet. The manufacturing method of the multifunctional composite material bullet-proof helmet comprises the steps that a hybrid fabric is manufactured from two or more than two of high-performance carbon fiber, aramid fiber and ultra-high molecular weight polyethylene fiber, and then a prepreg is manufactured from a thermosetting / thermoplastic composite resin adhesive containing a special filler; the bullet-proof helmet is manufactured in a mold pressing process through a combined paving technology of multiple materials, and electronic information components are embedded in a prepreg layer in the mold pressing process. The bullet-proof helmet formed by the technology comprises a rigid strengthening layer, a bullet-proof layer, a back bulge prevention layer, a buffer layer and multiple structures of an embedded electronic information module and the like, has the advantages of light weight, high strength, high rigidity, corrosion resistance, low bullet-proof back bulge, good water resistance and the like, and is integrated with various electronic information functions of infrared stealth, GPS (Global Position System) positioning, night vision, video transmission and the like.

Description

technical field [0001] The invention relates to a bulletproof helmet, in particular to a multifunctional composite material bulletproof helmet and a manufacturing method thereof. Background technique [0002] Bulletproof helmets are an important protective equipment for individual soldiers. The development of modern bulletproof helmet materials has gone through the process from metal to non-metallic composite materials. During the Second World War, the bulletproof helmets used by countries around the world were mainly made of high manganese steel or special steel stamping. The metal bulletproof helmet has the disadvantages of heavy weight, unstable bulletproof performance, high electrical conductivity, low heat insulation performance, and secondary rebound of projectiles. and other serious problems. With the emergence of high-performance fibers and technological development, special fiber-reinforced composite materials with high toughness, high tensile strength, and high mo...
