Abstract
Because of their lightweight and corrosion resistance, composite materials are being used more often in the transportation industry to create ship surfaces. The majority of composite materials that are employed are costly, naturally non-degradable synthetic fiber-reinforced composites. In order to become a new invention for the development of environmentally friendly composite material technology for ship hull construction, the development of natural fiber-reinforced composite materials must be pursued. An examination to determine the tensile strength and bending strength of composites with rattan and jute fiber reinforcement with variations without NaOH alkaline treatment, 5% NaOH and 10% NaOH alkaline treatment and fiber volume fraction 25%; 30%; 40%. The method uses hand layup method. The results of tensile and bending tests showed that rattan fiber composites and jute fiber composites could not yet be used as reinforcing fibers to replace fiberglass in the manufacture of ship hulls because they did not meet the minimum standards from BKI. Overall the composition of the rattan fiber composite is close to the minimum standard from BKI, namely the alkaline treatment of 5% NaOH, 30% volume fraction with a tensile strength of 55.266 MPa. While the composition of the jute fiber composite is close to the minimum standard from BKI, namely the alkaline treatment of 10% NaOH, 40% volume fraction with a tensile strength of 184.175 MPa. As for the bending strength, rattan fiber reinforced composites without alkali treatment, 30% fiber volume fraction with a value of 123.341 MPa and jute fiber composites with 5% NaOH alkali treatment, 40% fiber volume fraction with a value of 283.105 MPa.
