1K Carbon Fiber Sleeve

Lightweight 1K Carbon Fiber Braided Sleeve for Composite Tube Reinforcement, Wrapping & Precision Strengthening

1K Carbon Fiber Sleeve is a lightweight tubular braided reinforcement made from 1,000 filament (1K) carbon fiber tows, designed for wrapping and reinforcing tubes, rods, shafts, pipes, and cylindrical composite parts. Due to its fine tow structure, 1K braided carbon sleeve provides a smooth braid appearance, excellent conformity, and high strength-to-weight ratio—making it ideal for precision composite reinforcement and cosmetic composite tube applications.

Unlike flat carbon fiber fabrics, carbon fiber sleeves are supplied in a tubular form, allowing continuous reinforcement around round structures. The 1K carbon fiber braided sleeve is especially preferred where lightweight performance, clean finish, and easy resin wet-out are required.

This product is widely used in UAV/drone components, sports equipment, marine parts, automotive trims, robotics, and high-quality composite tube manufacturing.
