Square Carbon Fiber Tube

Carbon fiber offers technical properties that are popular in various applications where its high strength-to-weight ratio is of importance. In addition to its high strength-to-weight ratio, carbon fibers are thermally and electrically conductive.  They have high tensile strength, low density, low weight, low thermal expansion and excellent fatigue resistance.

One of the advantages of carbon fiber and composites is that virtually any shape or size can be fabricated. Which means it can also produce different shapes according to the needs of different shapes of buyersAll that is required is a tool, or mold, that is used to form the layers of carbon fiber.

A carbon fiber square tube is a high-performance composite structural component designed for applications requiring flat surfaces, anti-rotation stability, and precise alignment. Compared with round tubes, square carbon fiber tubes offer superior mounting convenience and structural control, making them ideal for frames, supports, and load-bearing assemblies.

Specification:

Feature:

1.Manufacturing Process & Technical Considerations

Controlled fiber orientation for load paths

Precision internal mandrels or molds

Tight control of corner radius and wall thickness

Stable curing processes to prevent warping

This technical capability positions runway as a professional manufacturer within the Carbon Fiber Tube category, rather than a generic composite supplier.

2.Standard & Custom Carbon Fiber Square Tubing

While some standard sizes are available, most applications require custom carbon fiber square tubing to match specific structural or assembly needs.

Our customization options include:

Outer width & height (square or rectangular)

Inner dimensions and wall thickness

Length and cut-to-size supply

Fiber grade (standard or high modulus carbon fiber)

Surface finish (matte, glossy, woven texture)

In addition to square profiles, runway also supplies related products such as rectangular carbon fiber tube, carbon fiber box tube, and other structural tube formats under our complete Carbon Fiber Tube manufacturing system.
