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

Abstract

<p>This research examines the strength of the UPRs-Cantula composite with the<br />addition of filler microcrystalline cellulose (MCC). Composites were created<br />with a volume fraction of 30% Vf and a 45° angle. This angle variation received<br />the same treatment as the others, including untreated, alkaline, and fumigation.<br />The treatment time for alkali treatment was 6 hours, while the treatment time<br />for fumigation was 10 hours. The strength of each angle variation was<br />determined, as well as its treatment of tensile strength, modulus of elasticity,<br />and Poisson's ratio UPRs-cantula composites. According to the results, the<br />alkali treatment produced the highest tensile strength and elastic modulus<br />values. The highest Poisson ratio value was discovered without treatment at a<br />45°. The alkaline treatment yielded the highest tensile strength and modulus of<br />elasticity test results. The pullout fiber fracture dominated the untreated<br />composite fracture, whereas the fiber breakage fracture dominated the alkaline<br />treatment.</p>
