The Influence of Fiber Composition on Tensile Properties and Machinability of Polyester/Biduri fruit fiber composites

Abstract

Abstract

This research was carried out to investigate the tensile properties and machinability of polyester composite materials reinforced with biduri fruit fibers. Composite materials are supplied in a variety of fiber compositions made by hand lay-up. Tensile testing was used to obtain tensile properties using an Instron tensile testing machine, while to obtain machinability, the machining process was carried out using an Agma CNC milling machine with a drill and end-mill process, the machining results were observed on the cut surface to analyze the machining quality. From the tensile test results, tensile strength and modulus of elasticity can be obtained. The tensile properties obtained from composite materials do not show consistent results, this is due to the influence of the composite manufacturing process and the nature of the fibers which absorb very high water vapor. Observation of the machining traces shows that the machining quality improves when the fiber composition increases.
