Weaving process and differentiated performance

12K represents a single bundle of carbon fiber containing 12000 single filaments, paired with the classic 2×2 diagonal weaving process. The coarse fiber bundle structure significantly increases the fiber content per unit area, and its load-bearing, impact resistance, and tensile properties are far superior to 3K and 6K fine filament carbon fabrics.

The diagonal cross structure endows the fabric with soft drape characteristics, making it less prone to wrinkling for large curved components, ship hull surfaces, and large equipment casings. After forming, the diagonal lines are rough and clear, highlighting the industrial weight and texture.

Compared to plain 12K carbon cloth, the diagonal pattern has stronger bending toughness and is less prone to brittle cracking and delamination under long-term load; Compared with fine twill carbon cloth, there are fewer layers under the same thickness, greatly shortening the construction period, suitable for batch reinforcement of engineering projects and mass production of large industrial components.

The product has inherent advantages of carbon fiber: lightweight, acid and alkali resistant, anti-aging, high temperature resistant, and its service life is far longer than that of glass fiber and ordinary steel under the harsh conditions of marine environment, outdoor infrastructure, and heavy industrial equipment.

Third party authoritative measured performance data

All batches of 12K Twill Carbon Fiber Woven Fabric have been sent to CNAS certified testing institutions for a complete set of mechanical and corrosion resistance tests. The report is attached to the goods and the data is authentic without any false labels

1. Bidirectional tensile performance: 3850MPa in the warp direction and 3810MPa in the weft direction, with a strength difference of less than 1% between the warp and weft directions, and uniform heavy load without local fracture risk;

2. Interlayer shear strength: 98MPa, multi-layer overlay with strong bonding, long-term pressure resistance without delamination, suitable for long-term outdoor engineering;

3. Corrosion resistance test of seawater acidity and alkalinity: After 720 hours of salt spray immersion, the strength attenuation is only 2.5%, perfectly adapting to the high salt environment of ships at sea;

4. Fatigue bending test: 5000 cycles of reciprocating bending without broken wires or fiber slippage, and large curved components that undergo repeated deformation without cracking;

5. Resin immersion test: The anti-corrosion vinyl resin is completely immersed in 15 seconds, making it less prone to missing glue or bubble defects during large-scale construction.
