FAQ

Yes. Our engineering team supports customers during specification development, providing guidance on fabric selection, layup schedule recommendations, resin compatibility, and processing parameters. For aerospace, automotive, and construction customers, this consultation includes referencing applicable standards (ACI 440.2R, fib Bulletin 14, AMS 3970-series, IEC 61400). We also provide technical input during customer qualification testing, reviewing coupon test results and recommending adjustments to fabric specification or processing conditions as needed. This engineering support is available at no additional cost for qualified projects.

Our R&D center is equipped to develop custom carbon fiber fabric, pultruded plate, and prepreg formulations matched to specific application requirements. Typical custom development cycles run 4–12 weeks from specification agreement to qualified sample delivery, depending on complexity. Examples of recent development projects include hybrid carbon-aramid weaves for impact-resistant applications, specialty spread-tow fabric for visible aerospace interiors, and custom surface treatments for improved bonding with specific epoxy and vinyl ester resin systems. Development costs are discussed case by case and are often shared between us and the OEM partner.

Yes. We regularly supply OEM and private-label customers, including automotive aftermarket brands, sports equipment manufacturers, and specialty composite fabricators. Our OEM service includes customized packaging (neutral, client-branded, or co-branded), product labeling per your specifications, and documentation aligned with your internal material codes. Intellectual property protection is formalized through mutual non-disclosure agreements signed before any technical exchange. For brands requiring continuous OEM supply, we can reserve dedicated production capacity under an annual framework agreement.

We customize fabric weight (areal weight from 160 to 600 g/m²), weave pattern (plain, twill, satin, spread-tow), tow count (3K, 6K, 12K, and specialty counts), fabric width, roll length, and surface sizing treatment. For pultruded carbon fiber plate, we produce custom thicknesses, widths, and length cuts. Chopped carbon fiber is available in 3 mm, 6 mm, 10 mm, 15 mm, and 20 mm standard lengths; intermediate lengths can be produced for qualified volumes. Colored carbon fiber fabric is produced in red, blue, silver, gold, and custom shade variants.

Carbon fiber fabric rolls are wrapped in moisture-barrier film, placed on protective cores, and packed in reinforced cartons or wooden crates depending on destination and transit mode. Pultruded carbon fiber plates are bundled with protective spacers and crated in wooden cases that protect against bending and edge damage during transit. Prepreg products ship in refrigerated packaging with temperature indicators; prepreg is packed with dry ice or gel packs for air freight and refrigerated containers for sea freight, consistent with cold-chain requirements. All packaging is designed to withstand multi-modal international freight without product degradation.

We ship by sea freight (FCL and LCL), air freight for urgent shipments, and international courier (DHL, FedEx, UPS) for samples and small orders. Standard Incoterms offered include FOB (major Chinese ports, typically Shanghai or Ningbo), CIF, CFR, and DDP for qualifying destinations. We coordinate with freight forwarders nominated by the customer or use our own forwarding partners depending on the agreed Incoterm. Full shipping documentation — commercial invoice, packing list, bill of lading or air waybill, certificate of origin, and material certificates — is provided within two business days of shipment.

We accept international wire transfer (T/T), letter of credit (L/C at sight or with deferred payment), and for qualified long-term customers, open account (O/A) with agreed payment terms. Standard new-customer terms are 30 percent deposit on order confirmation with 70 percent balance payable before shipment. For repeat customers and volume contracts, we offer 30/70 payment splits with net 30 to net 60 terms on the balance. Payment is invoiced in USD or EUR; other currencies can be arranged on request. Bank details appear on every proforma invoice, and we do not accept payment to any account not explicitly listed on our official invoice.

Dry woven carbon fiber fabric stored in sealed moisture-barrier packaging at stable room temperature (15–30 °C, relative humidity below 70 percent) retains full mechanical properties for at least 24 months and typically longer. Pultruded carbon fiber plate has no meaningful shelf life in normal dry storage. Prepreg has a defined shelf life — typically 12 months at -18 °C with a documented room-temperature out-life of 30 to 45 days depending on resin formulation — and must be handled according to the product data sheet. Chopped carbon fiber retains properties indefinitely in dry, sealed storage. We mark production date on all packaging to support FIFO inventory management.

Post-delivery technical support covers processing troubleshooting, handling and storage guidance, and application engineering consultation. Customers who encounter processing issues — resin infusion anomalies, cure behavior questions, bonding performance concerns — can contact our engineering team with sample specimens or process data for review. For long-term customers, we schedule periodic technical reviews to share new product developments, discuss application roadmaps, and align on future supply planning. Storage guidance is particularly important for prepreg, which requires refrigerated storage at -18 °C and has a defined out-life at room temperature documented in the product data sheet.

Quality claims must be raised within 30 days of product receipt and supported by photographic evidence, test data where applicable, and reference to the original batch number printed on the roll or package label. We respond to claims within three business days and conduct an internal investigation of the referenced batch against our retained samples. Verified non-conformances are resolved through replacement shipment, credit note, or refund depending on the customer's preference and the nature of the issue. For significant claims involving downstream processing losses, resolution is handled through the warranty terms in the commercial agreement.

Our production facility operates under ISO 9001 quality management. Individual product test documentation typically includes tensile strength, tensile modulus, fiber areal weight, resin content (for prepregs), and dimensional tolerance results, issued as a mill certificate accompanying each shipment. For aerospace and structural strengthening customers, we can align batch testing with standards including ASTM D3039 (tensile properties), ASTM D3171 (fiber volume), and equivalent ISO test methods. Project-specific certifications (such as DNV type approval for marine applications) are supported through coordination with nominated testing laboratories.
