Description
This premium high-performance pultruded carbon fibre tube is engineered for exceptional unidirectional strength, stiffness and low weight. Manufactured using continuous carbon fibres aligned along the tube length, it delivers outstanding axial performance where rigidity and minimal deflection are critical.
Ideal for robotics, UAVs, RC models, automation equipment and high-precision frameworks, these tubes provide a reliable structural solution in demanding environments. A wide choice of diameters, wall thicknesses and lengths allows you to tailor the tube to your specific mechanical and weight requirements.
Product Features
- Available outside diameters from 2 mm, 3 mm, 4 mm, 5 mm, 6 mm and additional larger sizes to suit a range of structural and linkage applications.
- Choice of wall thicknesses including 0.5 mm, 0.75 mm, 1 mm, 1.5 mm and 2 mm for optimised strength-to-weight performance.
- Standard lengths of 1000 mm, 2000 mm, 2 x 2500 mm and 5000 mm to accommodate both compact builds and long-span structures.
- Unidirectional pultruded construction providing high axial stiffness and tensile strength along the tube length.
- Lightweight carbon fibre composite structure offering a very high strength-to-weight ratio compared with metals.
- Smooth, resin-rich outer surface suitable for bonding, machining and integration into composite assemblies.
- Electrically conductive material characteristics, typical of carbon fibre, for use where conductivity must be considered in the design.
Key Features and Benefits
- Provides exceptional rigidity with minimal added mass, helping to reduce overall system weight in UAVs and robotic arms.
- High axial strength improves resistance to bending and buckling, enhancing reliability in loaded structural members and booms.
- Range of diameters, wall thicknesses and lengths makes it easy to select the right tube for torque transmission, linkages or frame elements.
- Corrosion-resistant composite construction offers long service life in outdoor, humid or chemically challenging environments.
- Precise pultruded profiles and smooth surfaces support accurate cutting, drilling and bonding for custom assemblies.
- Low thermal expansion compared with many metals helps maintain dimensional stability in temperature-varying applications.

Frequently Asked Questions
Can these pultruded carbon fibre tubes be cut and drilled easily?
Yes, the tubes can be cut and drilled using appropriate tools such as fine-toothed saws or abrasive cutting discs and carbide or diamond-coated drill bits. It is advisable to support the tube during cutting, work slowly to minimise heat build-up and use suitable dust extraction and personal protective equipment when machining composites.
Are these tubes suitable for outdoor and high-humidity environments?
These carbon fibre tubes are generally well suited to outdoor and high-humidity environments due to their corrosion-resistant composite construction. However, for long-term exposure, it is good practice to seal any cut ends and drilled holes with resin or a suitable coating to help protect the fibre edges and maintain appearance.
How do I choose the right diameter and wall thickness for my application?
Select the outside diameter and wall thickness based on the loads, span length and stiffness required in your design. Larger diameters and thicker walls provide higher bending stiffness and strength but add weight. For weight-sensitive applications such as UAVs, use the smallest size that safely meets your calculated load and deflection requirements, and consider testing a sample in your specific setup.
