Carbon fiber tubes, also known as carbon fiber reinforced polymer (CFRP) tubes, are lightweight and high-strength structural components. They are made by winding or wrapping continuous carbon fiber strands around a mandrel, which are then impregnated with a resin matrix, typically epoxy. This combination of carbon fibers and resin provides excellent strength-to-weight ratio, making them ideal for applications where lightweight yet strong materials are needed, such as in aerospace, sports equipment, and construction. They are also resistant to corrosion and have good thermal stability.
