High-Performance Composite Structure 100% 3K Carbon Fiber Square Tube

High-Performance Composite Structure 100% 3K Carbon Fiber Square Tube

3K Carbon Fiber Square Tube is a high-performance composite structure made from 3K woven carbon fiber reinforced with epoxy resin. It combines exceptional strength, lightweight properties, and durability, making it an ideal choice for applications requiring rigidity and precision.

Carbon fiber square tubes, also known as carbon fiber square profiles or carbon fiber box sections, are hollow structures with a square cross-section made from carbon fiber reinforced polymer (CFRP) composites.

Carbon fiber square tubes are manufactured using state-of-the-art techniques, including pultrusion as well as compression molding technique to ensure high quality and durability. In the pultrusion process of fabrication of carbon fiber tubing the continuous pulling of carbon fiber composites is mixed with resin matrix through heated forming dies to create continuous length of tubes which provides tubes with unidirectional properties.

In compression molding, on the other hand, involves multiple wraps of carbon fiber prepregs in various weave types. The result is a densely reinforced carbon composite with excellent strength and stability. Our carbon fiber square tubes are available in multiple surface textures, including twill weave and plain weave, and come in a gloss or matte finish. Due to the square shape, it has a better areal moment of inertia which gives higher bending strength. When compared to circular tubes it is perfect for lightweight stiff applications.
