Bullet proof helmet and preparation method thereof

Abstract

The invention discloses a bullet proof helmet and a preparation method thereof. The bullet proof helmet comprises a thermoplastic high polymer material and a fiber-reinforced composite material, the thermoplastic high polymer material comprises one or more of nylon, makrolon and polypropylene material, the fiber-reinforced composite material is made of one or more of carbon fiber, aramid fiber, fiberglass and high performance fiber, and the bullet proof helmet is integrally formed through an injection molding process; due to integral injection molding, the production efficiency is improved, and the bullet proof helmet has a better bulletproof capability, and can effectively prevent fractures caused by local formation, and the bullet withstanding performance is improved.

Description

technical field [0001] The invention relates to a bulletproof helmet, in particular to a bulletproof helmet and a preparation method. Background technique [0002] In recent years, terrorist attacks have continued to occur in various countries, and personnel from various countries have stepped up research and development in the field of security protection. In my country, with the development of social economy and the improvement of people's awareness of safety protection, the demand for safety protection equipment is increasing. The state also clearly specified in the "Twelfth Five-Year Plan" to increase support for the field of public safety. [0003] The material classification of bulletproof helmets is mainly divided into metal, non-metal and composite helmets (a mixture of metal and non-metal). Although metal helmets have good bulletproof performance, they are heavy and inflexible to wear, which seriously affects the combat effectiveness of soldiers. However, bulletpr...

AI Technical Summary

Problems solved by technology

Although metal helmets have good bulletproof performance, they are heavy and inflexible to wear, which seriously affects the combat effectiveness of soldiers.

However, bulletproof helmets made of composite helmet materials are prone to sticking, delamination, or bubbles during the production process. Non-metallic materials are currently used more and have a wide range of application space. Most non-metallic materials use ultra-high molecular weight polyethylene. Fiber and aramid fiber are two materials. UHMWPE fiber helmets are lighter, but helmets made of general fiber weaving methods are more expensive, and the molding process is more complicated and less efficient.
