3K Carbon Fiber Square Tube matte 20x18x1000mm

3K Carbon Fiber tubes are excellent replacements for heavy metal parts in many engineering projects. This 20mm square tube offers a superior strength-to-weight ratio compared to aluminum or steel. Specifically, it uses high-modulus T700 unidirectional prepreg carbon fiber for maximum lateral strength. The 3K matte finish provides a professional and sleek appearance for your builds. Because it is lightweight, it significantly reduces the overall mass of your structures. Many builders prefer this roll-wrapped version over cheaper pultruded alternatives. It delivers the rigidity needed for high-performance applications without the weight penalty of traditional materials.

Key Features

The roll-wrapping process creates a very durable and stable structure. Firstly, technicians lay multiple layers of carbon fiber around a precision mandrel. Afterward, they spiral-wrap the assembly with heat-shrink tape before curing it in an oven. This method ensures the fibers stay aligned for optimal structural integrity. Furthermore, the tube is naturally UV resistant and highly resistant to corrosion. Consequently, it performs well in harsh outdoor environments or marine settings. It also provides electrical and thermal non-conductivity for sensitive electronic projects. However, users should avoid applying heavy crushing forces directly across the diameter. This tube is designed to handle immense loads along its length instead.

Specifications

This high-quality tube features a 20mm outer width and an 18mm inner width. It comes in a standard length of 1000mm for versatile project use. The wall thickness is precisely 1mm to balance weight and durability. Moreover, the T700 carbon fiber material ensures a high modulus of elasticity. The matte 3K weave surface is scratch-resistant and easy to handle. In addition, the hollow square profile makes it easy to mount on flat surfaces. It weighs much less than a steel tube of the same dimensions. This makes it perfect for weight-sensitive designs in robotics or aerospace.

Applications

You can use this carbon fiber tube in a wide variety of industries. For instance, it is a popular choice for large drone frames and camera gimbals. It also serves as a strong structural support for remote-controlled aircraft wings. Additionally, hobbyists use these tubes to build lightweight robotic arms and skeletons. The square shape allows for easy attachment of brackets and motors. Meanwhile, it is ideal for telescope mounts and tripod legs. Because it resists corrosion, it also works well for outdoor sports equipment. You can easily cut it to your desired length using a fine-tooth saw.
