Carbon fiber tubes, also known as carbon fiber pipes, are tubular profiles made by pre-impregnating carbon fiber composite materials with styrene-based polyester resin and then heating and curing them. During manufacturing, various profiles, such as round tubes, square tubes, and sheets, can be produced using different molds, and can be surface-finished with 3K coating. They are used in infrastructure repair such as sewage transportation and in high-tech fields such as medical CT scanner supports and drone components.
This tube is composed of multi-layered carbon fiber reinforced composite materials, featuring high strength (T300 grade tensile strength 3500MPa), lightweight (30% lighter than aluminum alloy tubes of the same size), corrosion resistance, and a low coefficient of thermal expansion. Manufacturing processes include winding and pultrusion; small-tow carbon fiber tubes exhibit more stable performance.
