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 combination of several or more different materials, which produce better properties than their composition properties. The process of making composites can be done with a pressing method which can reduce voids. This pressing method can use a hydraulic press machine. This study aims to design and analyze a hydraulic press machine with a capacity of 20 tons. The design process begins with designing a 3D model using Solidwork Software. Numerical simulation using the finite element method by providing several variations in pressure loads ranging from 5-20 MPa. The results of the analysis show that the maximum von Mises stress is 79.70 MPa with a maximum deformation of 0.0176 mm and the smallest value of safety factor is 2.595. Based on these results, the press machine design is claimed to be safe to operate.
