Product Core Analysis

Weaving process and core product advantages

Bi-directional Twill Carbon Fiber Woven Fabric adopts a standard 2×2 bidirectional interlaced twill weaving process, where carbon fiber bundles are orderly interwoven diagonally in both warp and weft directions, distinguishing it from short boards that are subjected to single force in unidirectional fabrics.

This achieves balanced mechanical properties in both warp and weft directions, and the formed structural components will not experience unilateral warping or local cracking problems. The twill weave structure comes with a soft drape property, which greatly improves the adaptability of the curved surface covering compared to the same weight bidirectional plain carbon cloth.

The curved shell, irregular mold, and curved workpiece covering are not easy to accumulate wrinkles. After forming, the diagonal texture is clear and three-dimensional, and after polishing, it presents a high-end carbon fiber texture, balancing structural strength and appearance decoration effect. The product inherits the core characteristics of carbon fiber, such as lightweight, high tensile strength, acid and alkali corrosion resistance, aging resistance, and fatigue bending resistance.

Its deadweight is only one fifth of steel, and it is not easy to deform and fail after long-term outdoor, wet, and corrosive use. Covering the full specifications of 3K fine wire appearance parts, 6K medium wire universal structure, and 12K thick wire heavy-duty engineering, it takes into account multiple scenarios such as civil modification, industrial manufacturing, and maritime reinforcement, with strong versatility.

Third party authoritative measured performance data

All incomingBi-directional Twill Carbon Fiber Woven Fabric batches are synchronously sent for inspection to a third-party CNAS certified laboratory. The measured data is true and traceable, and the report is issued with the goods without any false or exaggerated labeling

1. Bidirectional tensile balance: The difference in tensile strength between the warp and weft is controlled within 1%, and the two-way force is synchronized. Symmetrical components are not easily deformed under long-term load;

2. Interlayer bonding strength: average 92-98MPa, multi-layer laminated composite without delamination, no risk of delamination during long-term use in outdoor engineering;

3.720 hour acid alkali salt spray corrosion resistance test: overall strength attenuation is less than 3%, suitable for ship and chemical anti-corrosion scenarios;

4. Repeated fatigue bending test: 5000 times of repeated bending without broken wires or fiber slippage, with outstanding durability of frequently deformed workpieces;

5. Resin infiltration rate: At room temperature, the epoxy resin is completely soaked in 10-15 seconds, significantly reducing the occurrence of large areas of construction bubbles and adhesive defects.

Case: Industrial Equipment

An industrial composite manufacturer needed a durable, high-quality surface layer for large curved molds used in producing fiberglass tanks and vessels. Previous plain weave carbon fabric caused wrinkling on the compound curves, requiring extensive post-processing to achieve a smooth finish, adding time and labor costs.

Solution: JUN TENG recommended 6K 400g bi-directional twill carbon fabric for its superior curved surface conformability and balanced strength. The fabric was vacuum-infused with high-temperature epoxy resin.

Outcome: Wrinkle-free layup was achieved on all curved sections, reducing post-processing time by 60%. The final molds delivered a smooth, uniform surface with clear diagonal twill texture, eliminating the need for additional surface filling and sanding. The manufacturer has standardized on JUN TENG twill fabrics for all curved mold projects.

Frequently Asked Questions Area

Q1: How to choose between bidirectional twill carbon cloth and plain carbon cloth?  

A: If the product has curved surfaces and pursues high-end decorative effects, priority should be given to bidirectional diagonal lines; Pure flat load-bearing molds, control procurement costs, choose bidirectional plain weave for higher cost-effectiveness.  

Q2: Your company is a wholesaler, can you provide a small amount of sample testing? How to deduct the sample fee?  

A: Support the application of small-scale samples, only charging the cost of basic materials. For subsequent bulk wholesale orders, the full payment of the samples will be directly deducted from the payment, and process reference instructions and testing reports will be included as a bonus.  

Q3: Is there a significant price advantage for first-hand sources compared to other merchants? Is there a discount for bulk purchases?  

A: We directly source goods from our factory in 2018, eliminating the need for multiple layers of distribution and price increases, and offering more favorable pricing for the same quality; Full roll and full container engineering orders are discounted in multiple tiers, with higher purchase quantities resulting in lower unit prices.  

Q4: Can this double-sided twill carbon cloth be exported overseas, and are the customs clearance documents complete?  

A: Fully supports global exports, with a full set of Chinese and English qualifications, testing reports, and customs clearance documents all available for free, in compliance with environmental import standards in Europe, America, and Southeast Asia, ensuring smooth and unobstructed customs clearance.  

Q5: What conditions are required for storing carbon cloth, and is it prone to moisture damage and performance?  

A: Unopened packaging can be stored in a cool and dry place, and the paving construction should be completed within one week after opening; Long term stocking can be paired with moisture-proof bags for sealing, as moisture can slow down the resin infiltration rate and affect the strength of the finished product.

Q6: I'm not sure which specification I need. Can you help me choose?

A: Absolutely. Send us your project requirements—component shape (flat/curved), size, load expectations, and appearance requirements. Our engineers will recommend the optimal 3K/6K/12K specification and layer count within 24 hours. Free consultation, no obligation.

Q7: Can I order multiple specifications in one shipment?

A: Yes. We support mixed orders—3K for decorative layers, 12K for structural layers, all in one container. This simplifies procurement and reduces shipping costs for multi-component projects.

Q8: Is there a minimum order quantity for mixed specifications?

A: No minimum for standard stock specifications (200g/240g/400g/450g). You can order as little as a few meters for each specification. Custom weights have a minimum of one full roll per specification.
