A study on the design for high-strength composites applied to the intermediate shaft

The purpose of this study is to determine the correct estimation of the concept design for high strength composites applied to the intermediate shaft of a ship. Recently, the application of composites has increased in the ship industry area for weight reduction and marine environmental protection. Carbon fiber reinforced plastic (CFRP) has characteristics of high strength, high elasticity and high corrosion resistance. Therefore, it is a suitable material for reducing the weight of the ship. So, weight reduction and high fuel efficiency can be expected. However, little research has been carried out on the technology development of a composites shaft for ships. In this study, analysis is carried out on the application of a high-strength CFRP shaft.
