Compared with the traditional watercraft materials, the composite materials of CNT fiber have many advantages. Firstly, the composite materials of CNT fiber are good in mechanical strength. The ships made of it are light in weight and low in fuel consumption, with a relatively simple construction process, short cycle of assembly, and convenient forming. Hence, its construction and maintenance expenses are far lower than that of steel ships. In the meantime, composite materials of CNT fiber are also good in fatigue resistance performance. Additionally, marine life are more difficult to co-adhere on the surface and the ship is resistant to corrosion due to the chemical inertness on the surface of CNT fiber, which are also the important considerations of material selection for shipbuilding. Hence, composite materials of CNT fiber have very unique comprehensive performance advantages in watercraft manufacturing.
