Knitted Carbon Fiber Sleeve

Flexible Knitted Carbon Fiber Sleeve for Composite Tube Wrapping, Cable Protection & Lightweight Reinforcement

Knitted Carbon Fiber Sleeve is a tubular knitted reinforcement sleeve made from high-performance carbon fiber yarns. Unlike braided sleeves, knitted sleeves have a more flexible loop structure, offering excellent stretch, softness, and easy conformity on irregular shapes, bends, and varying diameters.

This product is widely used for composite tube wrapping, lightweight reinforcement, protective sleeving, and insulation/protection applications where high flexibility is required.

Knitted carbon sleeves are especially preferred in applications where the sleeve must easily slide onto components, expand to fit, and conform smoothly without wrinkling—making them ideal for pipes, rods, cables, hoses, shafts, and composite reinforcement zones.

Frequently Asked Questions (FAQ’s)

Q1. What is knitted carbon fiber sleeve used for?
It is used for flexible tube wrapping, composite reinforcement in non-load critical zones, cable protection, hose protection, and easy-fit reinforcement sleeves.

Q2. What is the difference between knitted and braided carbon fiber sleeve?
Knitted sleeves are more stretchable and flexible, while braided sleeves provide higher stiffness and torsional strength for structural composite tubes.

Q3. Can knitted carbon fiber sleeve be used for vacuum infusion?
Yes. It can be used with vacuum infusion, vacuum bagging, and resin impregnation processes for composite reinforcement.

Q4. Which resin is best for carbon fiber sleeves?
Epoxy resin is recommended for best bonding strength, stiffness, and long-term durability.
