3K Carbon Fiber Round Hollow Tube (20×18×500mm)

This 3K Carbon Fiber Hollow Tube (20×18×500mm) is designed to provide high tensile strength, excellent rigidity, low weight, and strong corrosion resistance, making it an ideal replacement for aluminum or steel tubes in structural applications.

Manufactured using high-modulus unidirectional prepreg carbon fiber, this tube is created through a roll-wrapped construction process, which offers superior mechanical performance compared to standard pultruded tubes.

During roll-wrapping, carbon fiber layers are oriented in multiple directions and then oven-cured at high temperatures. This technique enhances fiber bonding, improves structural consistency, and results in a tube that is significantly stronger, more durable, and better suited for demanding engineering and hobby applications.
