6K Bidirectional Carbon Fiber Reinforcement Fabric

Our 6K bidirectional carbon fiber reinforcement fabric is woven using a 6K filament orthogonal plain weave. Unlike standard 12K coarse-tow fabrics, our material features finer, denser filaments and a uniform surface texture, ensuring superior conformability to curved surfaces while strictly adhering to the Grade I mechanical standards of the GB50367-2013 national standard for concrete reinforcement.

Product Features

Available in mainstream specifications of 200g/m²and 300g/m², the dry fabric is lightweight and pliable. It ensures uniform resin impregnation without air bubbles and provides perfectly balanced bidirectional load-bearing capacity, combining ease of handling during installation with multi-directional shear and torsional resistance.

Designed for precision reinforcement applications: historic building restoration, high-end interior renovations, small or complex-shaped beams and columns, precision equipment bases, thin-walled slabs, localized reinforcement of curved components, and repair of fine cracks in bridges.

It resolves common engineering issues associated with 12K coarse-tow fabrics, such as rough texture, buckling at tight corners, bubbling on thin substrates, and uneven surface finishes. The fine-denier fiber tows offer higher tear strength; the fabric does not fray when cut and requires no edge sealing. Its thin profile ensures a smooth finish without protrusions after plastering or painting, enabling discreet, precision reinforcement.

Available in widths from 500mm to 1270mm and standard 100m rolls, supplied as a complete system with matching Grade A impregnation resin. Suitable for diverse applications including structural reinforcement, industrial composites, and marine anti-corrosion.

Product advantages

The mainstream reinforced carbon cloth in the market is woven with 12K thick silk, suitable for large-area flat beams and columns; However, there are paving defects in a large number of refined, thin-walled, irregular, and indoor decoration projects. 6K fine denier bidirectional carbon fiber cloth fills the gaps in the industry from four dimensions: fiber fineness, construction adaptation, post finishing, and thin-walled protection. The five core unique advantages are:

1.6K fine denier yarn is densely woven, with curved surfaces and sharp angles covered without arching or hollowing. 12K coarse yarn bundles have a single thick filament and a wide yarn strip, which can easily form hard edges when laying in circular arcs, 90°beam column interior angles, and narrow gaps in floor slabs. Uneven wrapping of the adhesive layer can result in bubble hollowing; 6K single filament bundles are slender and soft, and the fabric surface can tightly adhere to extremely small curvature components without rigid protrusions. The drum can completely remove bubbles by rolling, reducing the rework rate of basement corners, curved balconies, and cylindrical details by 60%.

2.Thin and seamless, suitable for indoor decoration and protection of ancient architectural finishes. Traditional coarse silk carbon cloth reinforcement has obvious surface roughness, and plastering and latex paint brushing are prone to texture penetration; The 6K Bidirectional Carbon Fiber Reinforcement Fabric is finely arranged, and after curing, the composite layer is overall flat. The total thickness of the reinforcement layer is less than 0.5mm, and the finished surface is smooth without the need for thickening the leveling layer. It is perfectly suitable for renovation projects such as homestays, office buildings, cultural relics and ancient buildings that require strict external flatness, truly achieving invisible reinforcement.

3.The 1:1 balanced force distribution in both directions of latitude and longitude prevents stress concentration and cracking in thin-walled components. Thin walled floor slabs, lightweight partition walls, and steel structure thin plates are mostly bidirectional load-bearing components, with weak transverse bearing capacity in unidirectional fabrics. The gaps between ordinary coarse fiber bidirectional fabrics are large, and stress dispersion is uneven; The 6K fine fiber interlaced structure can uniformly conduct oblique, torsional, and biaxial tensile loads, suppress radiating cracks at floor openings, and prevent continuous expansion of intersecting diagonal joints in walls, while also achieving triple reinforcement effects of shear, tensile, and torsional resistance

4.Cutting does not cause loose threads, making on-site construction simple and reducing material loss. After cutting, the edges of 12K coarse threads are prone to loose threads and require additional edge locking treatment, wasting labor and carbon cloth; 6K fine denier fibers are interwoven tightly, and art knives and scissors can directly cut without loose or flying threads. Small spaces such as narrow ceilings and equipment shafts can be quickly cut into small pieces for use, reducing material cutting loss by 20%. Epoxy impregnated adhesive is evenly adsorbed, saving 15% of adhesive consumption compared to 12K fabric in the same area.

5.Resistant to fatigue and corrosion, balancing building reinforcement with special composite scenarios. Carbon fiber itself does not rust, is resistant to acid, alkali, and salt spray, and has a 6K fine woven structure with sufficient colloid penetration. After curing, it has stronger anti-corrosion and sealing properties; Except for civil buildings, it can be used for reinforcing ship bulkheads, chemical equipment bases, and small components of rail transit. It is not easy to peel off under long-term alternating loads and has a designed service life of over 50 years.

6K Bidirectional Carbon Fiber Reinforcement Fabric is a specialized material developed for fine, thin-walled, irregular, and indoor decorative reinforcement scenarios. It relies on the low bending orthogonal weaving process of 6000 fine denier carbon fiber raw fibers to break the application limitations of 12K coarse fiber bidirectional fabric in narrow curved surfaces, surface smoothness, and thin-walled protection. At mainstream engineering weights of 200g and 300g, it simultaneously achieves four core values: bidirectional balanced force, ultra-high surface adhesion, seamless thin adhesion, easy cutting and low loss. Unlike the thick wire carbon cloth used for heavy load reinforcement of side heavy components, this product focuses on local fine repair and invisible transformation, suitable for projects with high requirements for construction appearance and fitting accuracy such as the installation of elevators in indoor old houses, the repair of ancient buildings, irregular beams and columns, and equipment thin-walled bases. The mechanical properties of the material fully meet the national reinforcement standards, with low construction difficulty, minimal loss of auxiliary materials, and no need for additional thickening and leveling of the finishing material in the later stage. It is the preferred professional substrate for the reinforcement of small and medium-sized fine multi-directional load-bearing components.
