Core Analysis

A. Basic process principles of the product

6K "represents a single bundle of carbon fiber raw fibers containing 6000 carbon fibers. The bidirectional plain weave adopts an alternating weaving structure of warp and weft yarns, which is a mainstream industrial carbon fabric category that balances load-bearing performance, molding efficiency, and procurement cost. Compared to 3K filament carbon cloth, 6K filament bundle has a higher fiber content, with an increase of about 20% in tensile and shear strength per unit area, and stronger load-bearing capacity under heavy loads; Compared to 12K coarse wire carbon cloth, 6K cloth has delicate and uniform patterns, faster resin infiltration speed, less bubbles and delamination after laying, better surface flatness of the finished product, and a balance between structural strength and appearance effect. The plain weave structure is fully balanced in warp and weft force, without unidirectional mechanical shortboard, and is not easy to slip and crack when bending under force. It has excellent dimensional stability, acid and alkali corrosion resistance, aging resistance, and fatigue resistance. The weight of the same strength is only 1/5 of steel, and has outstanding advantages in lightweight.

B. Application zoning for all scenarios

1. In the field of heavy transportation: sports car covers, motorcycle body shells, new energy vehicle chassis reinforcements, ship hull reinforcements, and lightweight components for rail transit;

2. New energy wind power: small and medium-sized wind turbine blades, fan casings, and anti-corrosion lining for energy storage equipment;

3. Industrial manufacturing: composite material molds, heavy-duty fixtures, mechanical arm shells, anti-corrosion chemical equipment linings;

4. Sports equipment: large-sized surfboards, professional bicycle frames, heavy-duty off-road poles, racing protective gear;

5. Building reinforcement: seismic reinforcement of concrete beams and columns, repair of bridge structures;

6. High end models, large aircraft model racks, medical load-bearing equipment casings, etc.

Third party authoritative measured performance data

Each batch of 6K Bi-directional Plain Weave Carbon Fiber Fabric from Junteng is sent to a CNAS certified third-party laboratory for complete mechanical testing. The testing report is included with the shipment, and the core measured data is transparent and traceable

1. Bidirectional tensile balance: 3720MPa in the warp direction, 3690MPa in the weft direction, with a strength difference of only 0.8% between the warp and weft directions, and no force deflection under heavy load conditions;

2. Actual measurement of interlayer shear strength: 96MPa, firmly bonded after multi-layer stacking and composite, long-term load-bearing without delamination;

3.720 hour acid-base immersion test: strength attenuation is only 2.6%, and anti-corrosion performance far exceeds that of fiberglass cloth;

4.6000 cycles of reciprocating fatigue bending: the fabric surface has no broken threads or drawn yarns, suitable for frequent motion and stress equipment;

5.Resin immersion test: At room temperature, epoxy is completely immersed in only 14 seconds, significantly reducing the rate of rework in mass production.

Qualification certification section

As a legitimate supplier with complete import and export permissions, we offer a full set of Level 1 qualifications in both Chinese and English, which can be used for factory audits, project bidding, and overseas customs clearance. There is no risk of data being withheld

1. Enterprise level import and export right filing certificate, customs self declaration qualification;

2. ISO9001 Quality Management System Certification and ISO14001 Environmental Management Certification;

3. CNAS third-party mechanical testing report, ROHS environmental testing certification;

4. Industrial composite material safety production license, low halogen/flame retardant special testing report;

5. Export specific certificate of origin, inspection form, and complete set of customs declaration templates;

6. Original factory carbon fiber raw material warranty, with each roll of product traceable.

 JUNTENG procurement full chain service advantages

Frequently Asked Questions

Q1: How to choose 6K Bi-directional Plain Weave Carbon Fiber Fabric and 3K, 12K?  

A: Pursuing lightweight and delicate appearance, choose 3K for small parts; 6K for heavy-duty and cost-effective needs; 12K for large and simple structures with extremely low budgets. 6K bidirectional plain weave is recommended for industrial heavy-duty, automotive, and wind power industries.

Q2: Is there a fee for export customs declaration documents, and is the process complicated?  

A: The complete set of customs declaration and certificate of origin documents is provided for free, and our specialists organize them uniformly. Customers only need to provide basic order information without additional payment, greatly simplifying the customs clearance process.

Q3: Can a small amount of samples be provided for testing, and can the sample cost be deducted from the payment?  

A: Support the shipment of samples ranging from 1 to 10 square meters, with only basic material fees charged for the samples. After formal bulk orders are placed, the full amount of the samples will be deducted from the order payment, and testing reports and process references will be included as a bonus.

Q4: What are the storage requirements for 6K carbon cloth? Is it prone to moisture and failure?  

A: Store unopened in a cool and dry place, and cover and use within one week after opening; Long term storage can be paired with moisture-proof bags, as moisture can reduce the resin infiltration effect and affect the overall strength of the finished product.
