3K Full Carbon Fiber Square Tube High Strength Length 500mm OD 10mm 15mm 20mm 22mm 25mm 30mm
A carbon fiber square tube is a lightweight, high-strength structural component made from carbon fiber-reinforced polymer (CFRP). Its square profile offers excellent torsional resistance and easy integration into assemblies requiring flat surfaces or 90° connections.
Carbon fiber tube is used in high-tech carbon fiber composite material made of prepreg carbon fiber tube with high strength, stiffness, load load-bearing performance. And a lightweight (material density 1.9). Good corrosion resistance, good material stability. Decorative carbon fiber tube, at the same time, has the appearance of 3D effects. It can be used instead of metal, plastic, and other material members.
Carbon fiber square tubes are lightweight, high-strength structural materials made from premium carbon fiber reinforced polymer (CFRP). Their square shape provides excellent torsional stiffness and easy mounting for mechanical and structural applications.
Our carbon fiber square tubes are engineered for high-performance and precision applications where lightweight strength, stiffness, and dimensional accuracy are essential. Constructed from high-quality carbon fiber prepreg and cured under high temperature and pressure, each tube delivers exceptional rigidity, durability, and a professional carbon fiber appearance.
Unlike round tubes, the square profile provides flat mounting surfaces and enhanced resistance to torsional and lateral forces, making it ideal for projects requiring precise alignment and easy assembly. Whether used in structural frameworks, robotic arms, aerospace structures, or high-end sporting goods, these tubes ensure consistent performance even under demanding conditions.
Each tube is made with 3K twill or plain weave carbon fiber layers that offer excellent balance between strength, weight, and aesthetics. The surface can be finished in glossy, matte, or satin, providing both visual appeal and additional protection.
Key Features
- High Strength-to-Weight Ratio: Stronger than steel but much lighter.
- Excellent Rigidity: The square profile ensures high bending and torsional stiffness.
- Corrosion & Fatigue Resistant: Performs well in harsh environments.
- Smooth Surface Finish: Available in glossy or matte 3K twill/plain weave.
- Customizable Sizes: Length, wall thickness, and finish can be tailored.
Applications
- Aerospace and automotive structures
- Drone frames and RC models
- Industrial automation and robotics arms
- Sports and outdoor equipment
- Construction and marine engineering
