3K Satin Carbon Fiber Fabric

With 18 years of extensive experience in carbon fiber weaving, JunTeng operates a 40,000-square-meter standardized production facility equipped with a full suite of imported high-speed looms, molding equipment, and an independent mechanical testing laboratory. Unlike the dull finish typical of standard plain and twill weave fabrics, our 3K Satin Carbon Fiber Fabric utilizes a long-float satin weave technique that significantly enhances surface smoothness and produces a mirror-like gloss.

We consistently use T300-grade 3K carbon fiber filaments as raw material, maintaining strict control over fiber quality and breakage rates throughout production to ensure a flawless, particle-free surface. The satin weave structure features uniform porosity, allowing for rapid resin penetration—whether using epoxy, prepreg, or unsaturated resin. Upon molding, the fabric reveals a refined, brilliant black carbon fiber texture, free from pattern irregularities, graying, or whitening.

Lightweight yet highly tensile-resistant and durable against acid, alkali, and aging, this product is compatible with various molding processes—including hand lay-up, vacuum infusion, compression molding, and autoclave processing. It is widely used in applications such as automotive interior customization, high-end cycling equipment, gaming device housings, model aircraft, and premium decorative panels.

Third party laboratory measured data

All tests are reported by a third-party laboratory in cooperation with CNAS. Each roll of goods comes with a copy of the test, and the data is authentic and verifiable

1. Lightweight comparison test: Under the same area, 3K satin carbon cloth weighs only 1/5 of steel and 2/3 of aluminum alloy, significantly reducing the weight of various finished products and perfectly adapting to lightweight modification needs;

2. Cyclic bending fatigue test: A 200g standard specimen was subjected to 5000 cycles of reciprocating bending without delamination or fiber fracture, with a stable bending strength of 915MPa;

3. Acid alkali salt spray test: After continuous soaking in acid alkali solution and neutral salt spray for 72 hours, the fabric shows no corrosion or swelling, and the mechanical properties only deteriorate by 2.8%;

4. Resin infiltration rate test: Under the same construction environment, the infiltration rate of satin structure is 16% faster than that of plain carbon cloth, effectively improving production efficiency;

5. Long term storage stability test: After 18 months of sealed and light shielded storage at the original factory, retesting showed that the tensile strength attenuation was less than 4%, far better than the industry average level.

Factory authoritative qualification certification

As a professional carbon fiber weaving source factory with 18 years of experience, Junteng can provide scanned copies of the full set of qualifications for foreign trade customs clearance and project bidding:

1. ISO9001:2015 quality management system certification, implementation of standardized quality control processes throughout the entire workshop;

2. CNAS third-party mechanical performance testing report and ROHS environmental protection testing report, in compliance with European and American export environmental standards;

3. Customs self operated import and export filing qualification, supporting FOB delivery, can provide certificate of origin, factory certificate of conformity, and a complete set of testing reports;

4. Authorization for purchasing 3K carbon fiber raw materials from the original factory, with full traceability of the raw material source;

5. A member unit of the domestic composite materials industry association, possessing practical process patents related to satin weaving. The five quality inspection processes before leaving the factory: screening of raw silk entering the warehouse→weaving density sampling→weight and thickness testing→inspection of fabric and wool defects→tensile sampling testing. Unqualified fabrics are directly scrapped to prevent defective products from being shipped out.

After sales guarantee, quality assurance, and full cycle supporting services

5. Logistics protection plan: All carbon cloth is wrapped with thick waterproof wrapping film and hard paper tube packaging, with dedicated logistics for large orders to avoid transportation compression and moisture; Additional vacuum moisture-proof bag packaging is added to export goods.

Case : School Building Seismic Retrofit—Reinforced Concrete Column Strengthening

A 3-story school building in a seismic zone required column strengthening to meet updated building codes. The original columns had insufficient shear capacity and needed reinforcement without increasing column cross-section significantly, as classroom space could not be reduced.

Solution: JUN TENG supplied 3K satin carbon fabric (200g) with matching epoxy adhesive. The satin fabric's smooth surface and excellent conformability allowed tight wrapping around column corners without bridging or hollow spots. Two layers were applied via wet lay-up, followed by a protective coating.

Outcome: Post-installation testing confirmed shear capacity increased by 35%, meeting the seismic design requirements. The thin profile added less than 2mm to column thickness, preserving usable floor space. The smooth satin finish provided a clean, professional appearance suitable for an educational facility. The school passed structural inspection with zero rework.

FAQ

Q1: How should I choose 3K Satin Carbon Fiber Fabric and 3K plain or diagonal weave?  

A: Satin pattern is preferred for pursuing mirror high gloss and high-end appearance effects; Emphasizing structural load-bearing and cost control, diagonal stripes can be chosen; The budget is low, and plain weave is chosen for the use of basic structural components. Please inform us of the product's purpose, and we will recommend suitable specifications for you.  

Q2: Is it easy for satin carbon cloth to lose threads when cut? Is there a simple way to handle it? 

A: Compared to plain weave, there are fewer loose threads. Paste beauty paper on the cutting line at the cutting edge, and tear it off after cutting to greatly reduce thread loss. We will provide simple processing tips with the goods.  

Q3: Does it support free sample shipping? How to deduct the sample fee?  

A: 10×10cm small-sized samples are free of charge, and customers only bear the shipping cost; A small amount of fabric fee will be charged for samples larger than 1 meter, and the full amount of sample payment can be deducted for subsequent bulk orders.  

Q4: What are the storage conditions and shelf life of the fabric? 

A: Store in a cool, dry, and dark warehouse, away from moisture and direct sunlight; The original unopened sealed roll has a shelf life of 18 months, and it is recommended to complete the processing within 3 months after opening.  

Q5: Can the product be exported overseas, and what customs clearance documents can be provided?  

A: Supporting global foreign trade orders, we can provide a complete set of customs clearance documents including commercial invoices, packing lists, certificates of origin, ROHS environmental reports, and mechanical testing reports, which are compatible with customs standards in Europe, America, Southeast Asia, and the Middle East.  

Q6: Can we make pre impregnated satin carbon cloth? What is the minimum order quantity? 

A: Support epoxy pre impregnation processing. There is no minimum order quantity for regular stock, and the minimum order quantity for pre impregnated customized products is 50 square meters. Samples can be taken first to confirm the adhesion and molding effect.
