Four major hardcore highlights

Based on 18 years of production process iteration, our 6K Bidirectional Carbon Fiber Fabric has broken through the performance shortcomings of ordinary carbon cloth, achieving comprehensive upgrades in four dimensions: process, quality, adaptability, and cost-effectiveness. Each advantage is tailored to the actual construction, use, and procurement needs of customers, and is practical and reliable.

1.Technological advantages

Adopting upgraded high-density bidirectional flat weaving technology, the warp and weft densities are uniform and consistent, the fabric surface is flat and smooth, and the thickness is uniform, eliminating common problems such as looseness, fuzzing, broken threads, and deviation in the market. The fabric has balanced tension and synchronized bi-directional stress performance, making it less prone to wrinkling and deformation during construction. After applying glue, it has excellent wetting properties and can tightly adhere to the substrate. After curing, the overall structure is stable, greatly improving the reinforcement and repair effect.

2.Performance advantages

The addition of 6K large tow carbon fiber precursor makes the product light and strong, tensile resistant, impact resistant, acid and alkali resistant, and anti-aging. Compared to traditional steel and ordinary fiberglass cloth, it is lighter in weight and has higher strength, without increasing the load-bearing capacity of the substrate. At the same time, it can resist harsh environmental erosion such as moisture, acid and alkali, and high and low temperatures. Its service life is greatly extended, and it does not require frequent maintenance and replacement, making it suitable for long-term engineering use.

3.Qualification advantage

As a legitimate export grade factory, our 6K bidirectional carbon fiber cloth has a complete set of export customs declaration qualifications, quality inspection reports, and industry compliance certifications. Our products not only meet domestic industrial and construction standards, but also comply with international export testing requirements.

FAQ

Q1: What is the difference between 6K Bidirectional Carbon Fiber Fabric and 12K unidirectional fabric?

6K bidirectional fabric has balanced fiber density in both warp and weft directions, providing equal strength in two directions. It is ideal for multi-directional stress, curved surfaces, mold making, and general-purpose repair.

12K unidirectional fabric concentrates over 95% of fibers along a single axis for maximum strength in one direction. It is ideal for beam bending, column shear, and bridge girder strengthening.

Quick rule: Clear stress direction→unidirectional. Unclear or multi-directional stress→bidirectional. Complex curved surfaces→6K bidirectional (thinner, more flexible).

 

Q2: Can 6K bidirectional fabric be used for building reinforcement?

Yes, for crack repair on walls and slabs, seismic reinforcement of low-rise buildings, and non-primary structural elements. For main beams, heavy-load columns, and bridge girders, we recommend 12K unidirectional fabric. Consult a structural engineer for final specification.

 

Q3: What is the thickness and weight? Will it add significant load?

Areal density: 200g/m². Single-layer thickness: 0.22~0.24mm. Cured thickness: <0.5mm per layer. Carbon fiber weighs only 1/4 of steel, making it ideal for weight-sensitive applications.

 

Q4: Can it resist high temperatures and harsh chemicals?

Yes. Long-term service: -40°C to +120°C. Short-term resistance: up to 180°C. Retains over 95% strength after 500h acid/alkali/salt spray testing. Suitable for coastal, chemical, outdoor, and underground environments.

 

Q5: Can it be used with other brands of epoxy adhesive?

Yes, but we recommend our complete material system (fabric + primer + impregnating epoxy) for optimal wet-out and adhesion, clear accountability, and consistent cure cycles. If using third-party adhesive, perform a small trial layup first.

 

Q6: What is the shelf life and storage requirement?

Shelf life: 12 months. Store in a cool, dry place away from direct sunlight and moisture. Keep rolls horizontal; do not stack heavy items. Use within 6 months for large engineering projects.
