Description
Key Features
Lightweight, straight, and strong along the tube length.
Our pultruded carbon fiber tubes offer high axial stiffness, smooth surface finish, stable dimensions, and customizable diameters, wall thicknesses, lengths, and CNC machining options.
Applications
Designed for lightweight structural and support applications.
Suitable for UAV systems, robotics, automation equipment, measuring tools, support rods, industrial fixtures, sports equipment, and custom carbon fiber assemblies.
Pultruded vs. Roll-Wrapped Carbon Fiber Tubes
Pultruded carbon fiber tubes are a good choice for high axial stiffness, stable dimensions, and cost-effective long-length production.
Roll-wrapped carbon fiber tubes are more flexible in fiber layup design and are often used when torsional strength, hoop strength, or customized laminate performance is required.

Frequently Asked Questions
1. Can pultruded carbon fiber tubes be customized?
Yes. The outer diameter, inner diameter, wall thickness, length, surface finish, and machining details can be customized according to your project requirements.
2. What are pultruded carbon fiber tubes used for?
They are commonly used for UAV parts, robotics, support rods, industrial tools, automation equipment, sports equipment, and lightweight structural components.
3. What is the main advantage of pultruded carbon fiber tubes?
The main advantage is high stiffness and strength along the tube length, combined with low weight and stable dimensions.
4. Are pultruded carbon fiber tubes suitable for torsion loads?
They can be used in many structural applications, but if your project requires high torsional or hoop strength, a roll-wrapped carbon fiber tube may be more suitable.
5. Can you provide CNC cutting or drilling?
Yes. We can support cutting, drilling, slotting, and other machining services based on your drawings or assembly needs.
