UHMWPE UD fabric
Using ultra-high-strength and high-modulus polyethylene fiber as the base material, it is evenly spread by advanced high-tech equipment, and is impregnated and glued with high-strength elastomer resin and bonded by film, and then laminated by 0°/90° bi-orthogonal composite lamination. Sheet rolls. The product has excellent properties such as soft hand feeling, low density, abrasion resistance, impact resistance, and strong cutting toughness. It is widely used in soft body armor, bulletproof helmets, armor plates for vehicle and ship construction, bomb isolation facilities, special public anti-riot facilities, etc.
Bulletproof mechanism:
The PE UD fabric has a single-oriented arrangement and multilayer prepreg structure. The flexible long-chain structure can quickly disperse the impact energy of the bullet to a larger area, thereby reducing the depth of the dent of the bulletproof product and reducing the non-penetration caused by the impact. Sexual injuries, effectively protect important parts of the human body.
The flexible bulletproof vest made of PE UD fabric has the characteristics of light texture, softness and comfort, light and fit, and convenient to wear. It integrates ultra-high protection, ultra-light weight and soft comfort. It can improve the protection level at the same time. To maximize the comfort of wearing. 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) The high-efficiency continuous production line controls the tension of the fiber through a special tension adjustment system to ensure that each thread can be evenly subjected to sufficient 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 PE UD fabric;
3) In the bi-orthogonal compounding stage, it can achieve accurate 0 degree, 90 degree, 0 degree, and 90 degree angles of thermocompression bonding to ensure that the ballistic material exhibits the strongest anti-ballistic performance in tests and actual combat. Under the same bulletproof coefficient, the PE UD fabric produced by our company is thinner and lighter, which enhances the safety of the human body wearing protective armor
According to the number of layers, it is divided into single warp and single weft (2UD), double warp and double weft (4UD), 6UD, 8UD, etc.;
According to the film, it can be divided into single-sided film, double-sided film, etc.;
Divided by areal density: all areal densities between 60 grams and 300 grams, and can reach any softness and hardness according to customer requirements.
