Abstract
As the IMO has strengthened its environmental regulations to increase the energy efficiency of ships, the IMO has also begun to consider operational economics such as reducing energy consumption by reducing the weights of ships and their parts. This study conducts an analysis examining the application of a ship radar mast. The applicability of the laminated composite material was analyzed through tension, shear, compressive, and tension-tension fatigue tests and the FRP fatigue limit for one million cycles by the slope of the [Formula: see text]–[Formula: see text] curve was found to be about 231 MPa. It is expected that this method can be utilized in the design stage by predicting the fatigue life of radar masts for ships through fatigue testing.
