Lightweight High Stiffness Load-Bearing Round Carbon Fiber Tube – CFRP Tube for Performance Applications

The Round Carbon Fiber Tube is a high-performance, lightweight composite designed for maximum strength, stiffness, and torsional stability. Its precision round geometry ensures uniform stress distribution under bending, torsion, or axial loads, making it ideal for applications ranging from UAVs and robotics to motorsports and industrial machinery.

These tubes are manufactured by layering woven or unidirectional carbon fiber fabrics around a precision mandrel and curing under controlled heat and pressure. This process produces a dense, void-free structure with uniform wall thickness. Custom fiber orientations (0°, ±45°, 90°) can be engineered for specific load conditions, optimizing the tube’s performance under torsion, bending, or compression.

Round carbon fiber tubes are compatible with CNC machining, cutting, drilling, tapping, and bonding. The uniform wall thickness allows precise fabrication, clean edges, and reliable assembly with adhesives, inserts, or mechanical fasteners.

The Round Carbon Fiber Tube provides engineers, designers, and manufacturers with a high-strength, lightweight, and precise tubular solution. Its combination of advanced composite construction, customizable geometry, and premium finish makes it ideal for demanding aerospace, automotive, industrial, and high-performance applications.
