Carbon fiber composite materials have good mechanical properties. Hulls made of carbon fiber are more lightweight and fuel-saving, easily processed and quick forming, costless in construction and maintenance than steel ones. Secondly, the interface between the carbon fiber and the resin matrix can effectively prevent crack, strengthening the fatigue resistance of the material. Additionally, due to the inertness of carbon fiber surface, the hull is corrosion resistant and is hard for aquatic organisms to grow. This is an important factor in choosing the material of marine construction. The unique performance of carbon fiber in marine construction leads to the wide use of composites and drives the development of the carbon fiber industry.
