6K Carbon Fiber Sleeve

Heavy-Duty 6K Carbon Fiber Braided Sleeve for Composite Tube Reinforcement, Shaft Wrapping & Structural Strengthening

6K Carbon Fiber Sleeve is a heavy-duty tubular braided reinforcement made from 6,000 filament (6K) carbon fiber tows, designed for strengthening tubes, pipes, shafts, rods, rollers, and cylindrical composite components. Compared to 1K and 3K sleeves, 6K carbon fiber braided sleeve provides higher fiber volume per layer, resulting in faster laminate build-up, higher reinforcement efficiency, and improved structural performance.

Carbon fiber sleeves are supplied in a tubular form, allowing continuous reinforcement around round structures. 6K braided carbon sleeve conforms well to cylindrical and tapered parts, improving torsional strength and stiffness while maintaining low weight.

This product is widely used in automotive and motorsport drive shafts, marine tubes, industrial rollers, robotics structures, sporting goods, composite tube manufacturing, and infrastructure strengthening applications.
