Carbon fiber tubes, also known as carbon fiber pipes or carbon tubes, are made by impregnating carbon fiber composite materials into styrene-based polyester resin, followed by heating, curing, and pultrusion (or winding). During the manufacturing process, various shapes such as carbon round tubes, square tubes, and other profiles can be produced using different molds, offering a wide range of specifications.

Carbon fiber composite tubes are one of the most widely used and abundant carbon fiber base products, and they represent an important application form of carbon fiber composites. Like other applications, carbon fiber tubes are favored in many fields as lightweight materials due to the "light yet strong" performance advantages of carbon fiber.

Carbon fiber tubes can be categorized into carbon fiber round tubes, carbon fiber square tubes, carbon fiber elbows, carbon fiber rectangular square tubes, etc. Different forming processes can be applied depending on the specific use.

Properties: Acid and alkali corrosion resistance, high tensile strength, low density, high specific modulus, fatigue resistance, creep resistance, high-temperature resistance, dimensional stability, conductivity, thermal conductivity, low coefficient of thermal expansion, self-lubricating, energy absorption, and shock resistance.
