Kevlar UD fabric
The high-performance composite materials are made by arranging the aligned and parallel oriented polyaramid fibers (such as Kevlar® and Twaron®) in a specific way and pre-impregnating them with resins (such as phenolic and polyvinyl alcohol). The proportion of the fiber direction exceeds 95%, and they are specially designed for impact resistance and lightweight.
Feature
Ultra-high strength-to-weight ratio
Tensile strength: 3,000 - 3,500 MPa (axial direction), 5 times that of steel, and even more than carbon fiber UD fabric in terms of shear resistance.
Density: Only 1.44 g/cm³ (75% lighter than steel and 20% lighter than fiberglass UD fabric).
Extremely impact-resistant
Energy absorption: The energy absorption per unit surface density reaches 200 - 300 J·m²/kg (10 times that of steel).
Bulletproof level: Single layer can withstand pistol bullets (NIJ II level), and multiple layers of laminated can withstand bullets (NIJ III/IV level).
Flexible design
Cuttable, sewable or heat-pressed molded, capable of conforming to complex curved surfaces (such as body protection equipment).
Supports 0°/90° orthogonal layup or angle-gradient layup, optimizing multi-directional mechanical properties.
High-temperature resistance & Flame retardancy
Long-term temperature resistance: Stable performance from -196ºC to 200ºC, short-term tolerance up to 300ºC.
Limiting Oxygen Index (LOI): ≥28%, self-extinguishing when away from fire, no molten droplets.
Application fields
Personal protective equipment
Bulletproof insert panel: 6-10 layers of aramid UD + ceramic composite board, with a surface density of only 6-8 kg/m² (NIJ IV-level protection against 7.62mm armor-piercing bullets).
Aerospace
Helicopter armor: Hybrid layup with carbon fiber, reducing weight by 30% and resisting 12.7mm ballistic impact.
Transportation
Racing car body: Anti-impact energy-absorbing zone with aramid UD, 50% more efficient in absorbing energy than aluminum alloy.
High-speed rail interior: Flame-retardant aramid UD board

Guangdong Kaidun New Material Co., Ltd. is a technology - oriented enterprise specialized in the research, development, production, and sales of high - performance fiber - based textile products. It operates two production bases, one in Jiangsu Province and the other in Guangdong Province, with its operational headquarters situated in Foshan, Guangdong.
The Jiangsu base, namely Kaidun New Material Jinhu Co., Ltd., features a production workshop covering an area of more than 12,000 square meters and five production lines of needling machines. The Guangdong base, which is Guangdong Kaidun New Material Co., Ltd., is equipped with a 4,000 - square - meter comprehensive office building, a 10,000 - square - meter production workshop, three needling machine production lines, multiple looms, filament - cutting machines, wire - distributing machines, and slitting machines.
The company primarily focuses on developing textile or non - woven products using special high - performance fiber materials such as aramid, pre - oxidized fiber, ultra - high - molecular - weight polyethylene, basalt, polyimide, polyacrylonitrile, and carbon fiber, etc. These products are suitable for various applications including fireproofing, heat insulation, thermal preservation, sealing, weather resistance, reinforcement, cut - resistance, and puncture -resistance. They are widely used in industries such as the protect, aviation, aerospace, marine, automotive, photovoltaic, high - speed railway, firefighting, electrical appliances, chemical engineering, steel - making, thermoelectricity, textile, and plastics.
Guangdong Kaidun is an enterprise with independent R & D, customized production, and design capabilities. Its products are sold both domestically and overseas. In recent years, Kaidun Industrial has been dedicated to the research and development and productization of various new flame - retardant material products, striving to contribute to the national high - tech materials in breaking the foreign blockade. Simultaneously, it has vigorously developed high - tech technologies like intelligent manufacturing to drive the manufacturing industry from "Made in China" to "Created in China".
