The use of metals in ship components is increasingly reduced, this is because the metal has a heavy weight, a difficult manufacturing process, and easy to corrode. The ship components began to use non-metallic materials, such as composites. Composites commonly used in ship hull construction are fiberglass composites, this material is chosen because this material has strong, lightweight, rustproof and easy manufacturing processes. Fiberglass is a non-renewable material, so development needs to be done, one of them by utilizing natural fibers. The selected natural fibers are ramie fiber and coconut fiber, the choice of this material is based on the availability of abundant material and good mechanical properties. Then the specimen was made using a hand lay-up manufacturing method with a composition of the G-SSK-SR 90⁰ and G 90⁰ layer with BTQN 157 printed polyester, which was then subjected to tensile testing. From the test results it is known that the maximum tensile strength of the G 90⁰ composite is more optimal than the G-SSK-SR 90⁰ layer composite. Then the results of static simulation based on engineering thickness with the manufacturing method of these two composite variations can be declared feasible based on BKI mechanical standards and safety factor values.
