Aramid UD fabric is a kind of unidirectionally arranged flexible composite material of para-aramid fiber. It adopts imported ultra-high-strength aramid fiber as raw material, applies special equipment technology and environmentally-friendly aramid special matrix, and is composited by precision technology (using High-strength elastomer resin is impregnated, glued and film bonded, and then laminated by 0°/90° bi-orthogonal composite).
The product has the characteristics of light weight, flexibility, flatness, compactness, etc., and excellent comprehensive performance. It can be used to make all kinds of advanced soft body armor, bulletproof and impact resistant helmets, bulletproof shields, public safety equipment, transportation safety packaging, vehicles, ships and aircraft. Protective devices, explosion-proof devices, military armor, etc.
Aramid UD fabric has passed the inspection of the China Ordnance Industry Bulletproof Equipment Quality Supervision and Inspection Center and the Special Police Equipment Quality Supervision and Inspection Center of the Ministry of Public Security, and conforms to the "GA141-2010" standard. The product has successfully passed the NIJ0101.06 standard test of an authoritative overseas ballistic laboratory .
Technical features:
1. Using imported raw materials, the quality is stable and reliable, the ballistic performance is excellent, and the insurance coefficient is large;
2. High temperature resistance, anti-aging, anti-soaking, excellent stability and flame retardancy;
3. With excellent interception performance, it can effectively block high-speed bullets fired by pistols, submachine guns, light machine guns and other weapons, and can quickly deform them, greatly reduce penetration, absorb and dissipate the kinetic energy of warheads and fragments, and wrap them In the bulletproof layer, effectively protect the body parts;
4. It has the characteristics of resisting multiple impacts and shooting from multiple angles, which can effectively reduce the threat of blunt injury;
5. The use of special environmentally-friendly special substrates is resistant to aging, has no peculiar smell, and is non-toxic.
Bulletproof mechanism:
The aramid UD fabric has a single-oriented arrangement and multi-layer prepreg structure, which can quickly disperse the impact energy of bullets to a larger area, thereby reducing the depth of depression of bulletproof products and reducing non-penetrating damage caused by impact. Effectively protect important parts of the human body.
The flexible bulletproof vest made of aramid UD fabric has the characteristics of light texture, softness and comfort, light fit, and convenient wearing. It integrates ultra-high protection, ultra-light weight and soft comfort. While improving the protection level, It can guarantee the comfort of wearing to the greatest extent. Thereby it can better fit the body contour and facilitate movement. It can effectively reduce the deformation and depression of the crater and prevent blunt injuries.
Process Description:
1) Through a special tension adjustment system to control the amount of tension the fiber bears, to ensure that each thread can be evenly subjected to a large enough tension, and evenly spread to prevent overlapping threads. Ensure that the fibers are parallel to each other, and the force is more uniform. When subjected to an impact load, the impact bearing force is consistent, and it is not easy to break.
2) We use a self-developed glue system to precisely control the amount of glue used and the uniformity of glue to improve the quality of the non-lattice fabric;
3) In the bi-orthogonal compounding stage, it can achieve accurate 0 degree, 90 degree, 0 degree, 90 degree angle of hot press bonding, to ensure that the ballistic material is optimized in the test and actual combat.
