Abstract

Composite is a combination of two or more different materials that are combined with the aim of getting better strength from the constituent materials. This study aims to identify the effect of variations in fiber volume fraction and determine the proportion of the best volume fraction based on the tensile and flexural strength values in hybrid composites reinforced with EFB fiber and bagasse fiber. The composite manufacturing process was carried out using the compression molding method with variations in fiber volume fraction 6:14, 8:12, 10:10, 12:8 and 14:6. The tests carried out were density testing (ASTM C271) and tensile strength (ASTM D3039 ). The highest tensile strength test results were obtained at fiber volume fraction 8:12 with a value of 17.39 Mpa.

Abstract

Composite is a material that is formed from a combination of two or more constituent materials with a heterogeneous mixing process, which has different mechanical properties. This study aims to determine the effect of volume fraction and molding pressure of composite materials on tensile and bending strength. The volume fractions used are SK 25% & SB 5%, SK 20% & SB 10%, SK 15% & SB 15%, SK 10% & SB 20%, and SK 5% & SB 25%. Each change in printing pressure is carried out at a pressure of 60 bar, 70 bar and 80 bar. Composite testing was carried out using ASTM D3039 for tensile testing and ASTM D790 for bending testing. The results obtained are the highest tensile strength at E3 with a value of 23.573 MPa and the lowest tensile strength at C1 with a value of 9.199 MPa, then the highest bending strength at E2 with a value of 38.665 MPa and the lowest bending strength at B1 with a value of 30.318 MPa.
