摘要

This article presents a comprehensive study on using a polylactic acid (PLA) biocomposite reinforced with kenaf fibers as an alternative to aluminum in car body manufacturing. The car body is designed using SolidWorks software, and simulations are performed with ANSYS to evaluate the mechanical performance of the biocomposite and aluminum. This study aims to compare the mechanical properties of PLA biocomposites reinforced with kenaf fibers to those of aluminum, a classic material used in car body manufacturing. The results of the simulations indicate that the PLA/kenaf biocomposite has comparable mechanical properties to aluminum. Specifically, the PLA biocomposite’s stiffness and strength are slightly lower than aluminum’s, but its toughness and impact resistance are higher. Furthermore, the PLA biocomposite reinforced with kenaf fibers is lighter and eco-friendlier than aluminum aligning with goals for Sustainable Cities and Communities (SDG 11), Responsible Consumption and Production (SDG 12), and Climate Action (SDG 13). This study shows that using a PLA/kenaf biocomposite for car bodies has promising potential. Offering a pathway for Industry, Innovation & Infrastructure (SDG 9). These results could be of interest to car manufacturers looking for alternatives to traditional materials. Using a sustainable, biodegradable material like the PLA/kenaf biocomposite could provide significant environmental and economic benefits.
