Carbon Fiber Yarn 3K - 1kg Spool

Carbon Fiber Yarn 3K – 1kg Spool

Carbon Fiber Yarn 3K is a high-performance continuous carbon fibre tow consisting of 3,000 filaments per tow, supplied on a 1kg spool. Finer than 6K tow, 3K carbon fibre yarn is ideal for applications requiring tighter weave patterns, higher surface finish quality, and more precise composite layups — making it a popular choice for drone frame manufacturing, custom carbon fibre fabric weaving, and precision composite components.

Specifications

• Type: Carbon fibre yarn / tow

Key Features

• 3K tow — 3,000 filaments per tow for finer, tighter weave patterns and superior surface finish
• 1kg spool — generous quantity for production runs, prototyping, and ongoing composite work
• Epoxy compatible — works with standard epoxy resin systems for wet layup and filament winding
• Finer than 6K — ideal where tighter weave density and better surface aesthetics are required
• Weaving and braiding — produces high-quality carbon fibre fabric and braided sleeves
• Filament winding ready — suitable for winding carbon fibre tubes, rods, and structural components
• Lightweight and high-strength — exceptional stiffness and tensile strength for structural composite parts
• Drone and aeromodelling applications — ideal for manufacturing custom carbon fibre drone frames, arms, and panels

When surface finish and weave precision matter, Carbon Fiber Yarn 3K delivers the finer filament count your composite manufacturing process demands — from custom woven fabric to precision-wound structural components.
