Core Competitive Advantages

1. Weaving Process Advantage

High-density bidirectional plain weave with locked edges ensures a smooth, compact surface free from skipped threads, fuzzing, or misalignment. Edge-locking prevents yarn unraveling during cutting, eliminating the loose, light-penetrating defects found in low-grade carbon fabrics. Full resin penetration wraps every filament for superior bonding strength, reducing rework and material waste on site.

2. 12K Bidirectional Structural Strength

12K Bidirectional Carbon Fiber Fabric delivers higher load capacity, while bidirectional symmetry provides balanced tensile strength in both warp and weft directions—overcoming the single-direction limitation of unidirectional fabrics. For complex structures like curved molds, irregular beams, and marine hulls, no multi-layer cross-lamination is required, simplifying installation and reducing labor and adhesive costs.

3. Four-Stage Quality Control—Zero Acceptance Risk

Every batch passes four inspection checkpoints: raw material testing upon incoming, real-time weaving monitoring, finished product mechanical sampling (tensile & corrosion testing), and outgoing roll-by-roll specification verification. Each roll includes a batch-specific QC report, fully compliant with domestic tendering, project acceptance, and overseas customs clearance requirements.

4. Factory-Direct Procurement Service

Direct source supply with zero middleman markup. Free sample testing, custom widths (100mm–1500mm), and tiered wholesale pricing for long-term orders. Pre-sales engineering support for specification matching, real-time order tracking, post-sales installation guidance, and rapid replacement for quality issues. Domestic bulk shipping and export customs clearance assistance available. Long-term partners can lock in factory-base pricing.

Application scenarios

Building infrastructure reinforcement: widely used for strengthening cracks in bridges, factory beams and columns, floor slabs, tunnels, and seismic retrofitting of old residential areas. The product has an extremely light weight and will not damage the original building structure. It is suitable for harsh environments such as damp underground garages and coastal salt spray. It has strong durability and can be exclusively scheduled for engineering procurement. It has complete qualifications and worry free acceptance.

Fiberglass mold manufacturing: suitable for laminated molding of fan casings, yacht hulls, and industrial equipment casings. The 12K large wire bundle carbon cloth has sufficient thickness for single-layer molding, reducing the number of repeated layers and greatly improving mold production efficiency. It is the mainstream preferred material for long-term bulk procurement by major mold manufacturers

Lightweight transportation modification: can be used for reinforcing RV shells, go karts, surfboards, and drone structural components, balancing the advantages of ultra-high strength and lightweight, effectively reducing equipment weight, and adapting to bulk customization and procurement by foreign trade modification equipment merchants.

Industrial anti-corrosion equipment: 12K Bidirectional Carbon Fiber Fabric is applied to chemical tank body, mechanical wear-resistant shield, and reinforcement of robot structural parts. It has excellent acid and alkali resistance, corrosion resistance, and anti-aging performance. It can replace heavy metal plates, reduce equipment load, and effectively extend the service life of industrial equipment.

Procurement Notice

Some low-priced 12K carbon fabrics on the market are woven with recycled and mixed carbon silk, resulting in loose fabric surface and substandard strength. After construction, they are prone to delamination, cracking, and structural failure, greatly increasing the cost of later maintenance and replacement. JUN TENG's 12K Bidirectional Carbon Fiber Fabric is woven entirely with newly imported high-purity 12K continuous carbon fiber, without any recycled or adulterated fibers, ensuring stable and consistent phase and performance. Each batch of spot goods can provide third-party testing reports. Major engineering companies, foreign trade purchasers, and mold manufacturers are welcome to send free samples for comparison and actual testing.

If you have bulk procurement, specification customization, foreign trade export, or sample quotation needs, you can directly contact online customer service, provide project usage scenarios and procurement quantities, and immediately issue accurate quotations and a complete set of supporting qualification documents. Spot goods are cut and shipped on the same day, and long-term cooperative customers can apply for quarterly price locking and exclusive stocking plans.

FAQ

Q1: What is the actual tensile strength of this 12K bidirectional fabric?

Our 12K bidirectional carbon fiber fabric achieves a tested tensile strength of ≥4300 MPa in both warp and weft directions. This is 7-9 times stronger than ordinary steel and exceeds the GB 50367 standard requirements for structural reinforcement materials. All batches are third-party tested and accompanied by certified test reports.

Q2: Can I use this fabric with polyester or vinyl ester resin, or only epoxy?

This 12K bidirectional fabric is compatible with epoxy, polyester, and vinyl ester resins. For structural reinforcement and high-performance applications, we recommend epoxy for maximum bonding strength. For mold making and general composite manufacturing, polyester or vinyl ester are cost-effective alternatives. We recommend a small trial to verify resin compatibility with your specific system.

Q3: Can I use 12K bidirectional fabric for structural building reinforcement?

Yes. 12K bidirectional fabric is suitable for crack repair on floor slabs and walls, seismic reinforcement, and non-primary structural elements. However, for main beam, heavy-load column, or bridge girder reinforcement, unidirectional fabric is more efficient because it puts maximum strength in the primary stress direction. Always consult a structural engineer for final specification on load-bearing structural reinforcement.

Q4: What width options are available? Can I get custom slitting?

Standard stock widths are 100mm, 200mm, 300mm, 500mm, and 1000mm. We also offer custom slitting from 100mm up to 1500mm with no minimum order for standard widths. For custom widths, we can slit to your exact specification starting from a single roll. Contact our sales team with your requirements.
