Carbon Fiber Yarn and Tow are base materials for weaving, pultrusion, filament winding, prepregging and many downstream composite processes.
We can supply or source carbon fiber yarn and tow according to customer requirements, including selected Chinese and international brand options. Brand availability depends on stock, batch, order quantity, destination country and compliance review.
We do not imply official authorization unless separately stated. End-use, end-user and destination details may be required before quotation or shipment for selected high-performance carbon fiber materials.
The correct yarn should be selected by tow size, strength grade, modulus, sizing compatibility, package format, spreading behavior, fuzz level and customer processing method.

Material suitability should be verified through the customer's process, design requirements and application testing.
This is a practical shortlist for RFQ preparation. Final suitability depends on customer testing, resin compatibility and engineering validation.
Use the published 12K supply reference only for its stated scope; 3K, 24K and 50K requests require source-specific confirmation.
Specify tow size, grade, sizing, linear-density request, bobbin format and compatible downstream process.
Use neutral source or brand requests; availability depends on batch, stock, order quantity and compliance review.
End-use and end-user information may be required before quotation or shipment.
Brand availability depends on stock, batch, order quantity, destination country and compliance review. We do not imply official authorization unless separately stated.
Document availability depends on material family, specification, order agreement and batch. Final values are confirmed by official documents, not by website examples.
Material specifications, typical properties and recommended use.
Hazard information, handling guidance and safety measures where applicable.
Batch information and material characteristics when available for confirmed orders.
Packing method depends on roll size, component geometry, quantity and destination. Roll protection, cartons, pallets, labels and packing photos can be discussed before shipment.
Brand-specific supply can be discussed, but availability depends on grade, tow size, allocation, export terms and batch stock.
Please provide brand preference, grade, tow size, sizing requirement, package requirement, monthly quantity and downstream process.
Inquiry options include 1K, 3K, 6K, 12K, 24K, 48K and 50K carbon fiber tow. Final availability, grade, sizing, package and batch documents are confirmed for each quotation.
