Abstract
Salinity is a description of the amount of salt in water. The distribution of salinity in seawater is influenced by various factors such as water circulation patterns, evaporation, rainfall and river flow. The purpose of this study was to determine the effect of seawater salinity on the mechanical properties of ramie fiber composites (Boehmeria Nivea). The research methodology used to calculate tensile strength and flexural strength was based on ASTM 0638-02 and ASTM 0790-02 standards. The results obtained are for the maximum tensile strength obtained at 95.05 ± 13.57 MPa and a minimum of 34.93 ± 15.64 MPa, the maximum tensile strain is 0.09 ± 10−3% and the minimum is 0.04 ± 10−3%, the maximum tensile elasticity modulus is 1153.57 ± 86.25 GPa and a minimum of 893.04 ± 56.48 GPa. Meanwhile, the maximum flexural strength is 288.87 ± 26.60 MPa and the minimum is 193.42 ± 41.35 MPa, the maximum flexural strain is 0.02 ± 10−3% and the minimum is 0.01122 ± 10−3%, the maximum flexural modulus of elasticity is 19.94 ± 1.82 GPa and a minimum of 12.42 ± 2.32 GPa.
