Braided Carbon Fiber Biaxial Sleeve is a tubular composite reinforcement sleeve manufactured from carbon fiber yarns arranged in a biaxial braided structure, typically oriented at ±45°. This configuration provides balanced torsional strength, shear resistance, and uniform load distribution in lightweight composite components.
Designed for structural reinforcement rather than cosmetic covering, the sleeve conforms easily to round, tapered, or complex shapes and is compatible with resin infusion, vacuum bagging, and other composite manufacturing processes.

5-10 daysBraided Carbon Fiber Biaxial Sleeve is a tubular reinforcement sleeve manufactured from carbon fiber yarns arranged in a biaxial braided structure. The fibers are oriented at opposing angles, typically around ±45°, providing balanced strength, torsional rigidity, and uniform load distribution when used in composite structures.
This biaxial carbon fiber sleeve is widely used in composite manufacturing processes where high strength-to-weight ratio, directional reinforcement, and conformability over complex shapes are required.
The sleeve is produced using a controlled braiding process that interlaces carbon fiber yarns in two opposing directions.
Biaxial fiber orientation provides balanced mechanical properties
±45° fiber angles enhance torsional and shear strength
Open braided structure allows resin penetration and consolidation
Tubular form easily conforms to round, tapered, or irregular shapes
Compared with unidirectional or plain woven fabrics, biaxial braided sleeves offer improved structural efficiency in tubular and hollow composite components.
Carbon fiber is selected for its outstanding mechanical and physical properties:
High tensile strength and stiffness at low weight
Excellent fatigue resistance
Low thermal expansion
Good dimensional stability after curing
Suitable for high-performance composite applications
The braided structure distributes loads evenly, reducing stress concentrations within the finished laminate.
Braided Carbon Fiber Biaxial Sleeve is particularly effective in applications requiring:
High torsional stiffness
Improved resistance to bending and shear forces
Uniform reinforcement around the entire circumference
Reduced risk of fiber wrinkling during layup
These characteristics make it well suited for structural components subjected to dynamic or multi-directional loads.
This biaxial carbon fiber sleeve is compatible with a wide range of composite manufacturing methods:
Resin infusion
Vacuum bagging
Hand lay-up
Filament winding (secondary reinforcement)
Pultrusion and molding processes
The expandable braided structure allows easy positioning over mandrels, cores, or foam forms prior to resin impregnation.
Braided Carbon Fiber Biaxial Sleeve is commonly used in:
Aerospace and UAV components
Tubular reinforcements, arms, booms, and structural frames
Automotive and motorsport
Driveshafts, roll structures, suspension elements, and reinforcement tubes
Marine and sporting equipment
Masts, poles, paddles, and lightweight structural parts
Industrial and mechanical components
Composite shafts, rollers, pressure vessels, and support structures
Available in a range of nominal diameters
Expandable structure accommodates different mandrel sizes
Custom fiber weights, braid angles, and lengths available upon request
This flexibility allows the sleeve to be tailored to specific structural and processing requirements.
This product is selected when composite designs require:
Efficient biaxial reinforcement in tubular form
High strength and stiffness with minimal weight
Reliable fiber alignment during fabrication
Consistent performance in structural composite parts
It is not intended as a cosmetic covering, but as a structural reinforcement material.
For composite applications requiring lightweight, high-strength tubular reinforcement, Braided Carbon Fiber Biaxial Sleeve offers a proven and adaptable solution.
