At present, the helmets assembled by the active army mainly protect pistol bullets and fragments, but cannot protect against rifle bullets. The penetration energy of high-speed projectiles will also be transmitted through the helmet in the form of stress waves, causing varying degrees of damage to the soldier’s head and neck. Seriously endanger the lives of officers and soldiers. The company develops enhanced combat helmets for individual protection requirements under direct rifle shooting. The helmet body structure is designed by optimizing ultra-light, high-strength, high-modulus fibers and ballistics principles. It is innovative in anti-penetration, shock absorption and energy absorption, so that it can resist rifle bullets with kinetic energy several times more than ordinary pistols, and resist multiple rounds of elasticity Can be excellent. At the same time, it has significant blocking effect on defensive stray bullets and high-speed shrapnel. The performance will not be reduced in various harsh combat environments such as sea water, high and low temperature sudden changes, high altitude, salt spray and outdoor, and the service life is long (more than 5 years).
The appearance is the same as the ordinary helmet, and the helmet shell is slightly thicker. The helmet is equipped with a comfortable cushioning suspension and interior trim, and can be equipped with an open interface to connect with various portable optoelectronic devices such as communication systems and night vision devices to achieve toughness, light weight, multi-function and high efficiency.
Technological innovation:
1) Through the research and development of resin modification, the bulletproof fiber is fully infiltrated, the impact toughness of the composite material is improved, the local compression, shear damage and the internal and interlayer damage of the composite material are effectively reduced, and the friction resistance of the composite material to the penetrating projectile is increased. . According to the principle of impact dynamics, the peak load is reduced.
2) The helmet body is designed with a composite structure, and the helmet's elastic surface and wearing surface adopt different ratios of preferred materials to provide sufficient rigid support and effectively absorb kinetic energy.
3) Optimize the molding process parameters, design the guiding device for the deep cavity curved surface mold, accurately and evenly control the temperature field, and ensure the air tightness of the pipeline and the effectiveness of heat transfer, so that the thickness of each part of the helmet body is more uniform and the structure is more dense ; Coupling and interaction between layers can improve the synergistic effect of the fiber, which is conducive to the transmission of stress waves and the dissipation of impact energy.
4) The suspension interior is composed of chronic rebound memory foam, and has a strong ability to absorb shocks. This kind of cushion can automatically adjust the shape to adapt to different head shapes and provide better wearing comfort.
Application prospects:
It can be used as a new generation of individual protective equipment to prevent high-speed ballistic fragments on the battlefield and specific rifle bullets from direct firing on combat individuals, improve battlefield survivability, ensure combat efficiency, and reduce fatigue. It is cost-effective, protective and mobile. The advantages of coordination and economy.
