Effect of Alkaline Treatment and Fumigation (Fumigation) on the Mechanical Properties of Fiber Unsaturated Polyester-Cantula Composite with Compression Molding Method

Abstract

This research examines the strength of the UPRs-Cantula composite with theaddition of filler microcrystalline cellulose (MCC). Composites were createdwith a volume fraction of 30% Vf and a 45° angle. This angle variation receivedthe same treatment as the others, including untreated, alkaline, and fumigation.The treatment time for alkali treatment was 6 hours, while the treatment timefor fumigation was 10 hours. The strength of each angle variation wasdetermined, as well as its treatment of tensile strength, modulus of elasticity,and Poisson's ratio UPRs-cantula composites. According to the results, thealkali treatment produced the highest tensile strength and elastic modulusvalues. The highest Poisson ratio value was discovered without treatment at a45°. The alkaline treatment yielded the highest tensile strength and modulus ofelasticity test results. The pullout fiber fracture dominated the untreatedcomposite fracture, whereas the fiber breakage fracture dominated the alkalinetreatment.
