Braided 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.
Biaxial Braided Construction
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.
Material Characteristics
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.
Mechanical Performance Advantages
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.
Compatibility with Composite Processes
This biaxial carbon fiber sleeve is compatible with a wide range of composite manufacturing methods:
The expandable braided structure allows easy positioning over mandrels, cores, or foam forms prior to resin impregnation.
Typical Applications
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
-

Composite shafts, rollers, pressure vessels, and support structures
Sizing and Customization
-
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.
