Today, we will analyze the performance comparison between pultruded carbon fiber tube and steel pipe.
In terms of strength, the tensile strength of carbon fiber pipe made of composite with resin matrix is about 1500MPa, and the tensile strength of steel pipe (such as Q235) is only 370MPa-500MP. It is obvious from the comparison results that the tensile load resistance of carbon fiber pipe is much stronger than that of steel pipe.
In terms of fatigue resistance, the fatigue strength limit of steel pipes and other metal materials is 30% - 50% of their own tensile strength, while the fatigue strength limit of carbon fiber tubes is 70% - 80% of their own tensile strength. When working under long-term alternating load conditions, carbon fiber tubes have more stable performance and longer service life. Moreover, pipes are mostly used for structural parts, which can play a supporting role. After the metal pipes such as steel pipes are cracked, the damage degree will continue to increase, which may cause sudden fracture, leading to accidents. The fracture of carbon fiber pipe often goes through a series of processes such as matrix damage, cracking, interfacial debonding, fiber fracture, and when a few fibers break, the load will be distributed to other intact fibers through the transmission of the matrix, and the safety is guaranteed.

When working under long-term alternating load conditions, carbon fiber tubes have more stable performance and longer service life.
In terms of production cost and process, the production of steel pipe is more complete and mature, so the price is lower. The development history of carbon fiber pipe is shorter, so the production cost is higher, and the process is less mature.
In general, pultruded carbon fiber pipe has more advantages than steel pipe.
