What are Carbon Fiber Tubes?

Definition and Basic Characteristics

Carbon fiber tubes (also known as carbon fiber rods if they are stiffer and heavier) are predominantly cylindrical structures made from carbon fibers implanted in a polymer matrix, oftentimes an epoxy resin. They are however also available in other shapes such as rectangular or hexagonal, to suit different structural and design requirements. The CFRP tubes distinguish themselves in the market due to the high strength-to-weight ratio; they have more strength and are much lighter compared to their basic counterparts - like steel and aluminum. The carbon fibers provide high tensile strength, usually on the order of 3.5 GPa (Gigapascals), while the polymer matrix binds them together and provides some rigidity to the fibers for strengthening. Carbon fiber tubes also have a density of about 1.6 g/cm³ compared to steel at 7.8 g/cm³ and aluminum at 2.7 g/cm³.

Comparison with Other Materials

Carbon fiber tubes differ considerably compared to other materials. For instance, compared to steel and aluminum, carbon fiber tubes weigh approximately 70% and 40% less respectively, while having equivalent or better strength—application-related increased efficiency and performance, as seen in industries such as aerospace and automotive. In addition to this, carbon fiber tubes don't corrode like steel rusts over time or aluminum corrodes when the conditions dictate so. The modulus of elasticity for carbon fiber is about 230 GPa as compared to 200 GPa in steel and 69 GPa in aluminum, thus it shows that the CFRP tubes are stiffer and have less tendency to deform.

As for their thermal properties, Carbon fiber tubes again outperform traditional materials in terms of their thermal properties. Carbon fiber has a lower coefficient of thermal expansion (CTE) compared to steel and aluminum; that is, it expands and contracts less when subjected to variations in temperature. This dimension stability is highly demanded in applications where precision is a central requirement, as in aerospace and sporting equipment of high performance. Besides, carbon fiber's thermal conductivity is lower than metals, which makes it an excellent choice for applications requiring thermal insulation.

Besides that, any carbon fiber tube has greater fatigue resistance compared with its metal equivalents. Metallic materials, especially steel, and aluminum, upon experiencing cycles of load application and removal, tend to form micro-cracks, which will eventually lead to failure. Carbon fiber will maintain its integrity for a longer period under cyclic loading, a benefit particularly in aircraft structure applications and automotive parts where long-term durability is essential.
