In recent years, manufacturing industries have faced intense competition due to globalization. Companies have adopted various management philosophies to achieve greater success while emphasizing material properties for industrial component production. The automotive industry, in particular, requires strong and lightweight materials. Polymer matrix composites (PMCs) have emerged as a vital solution. PMCs consist of an organic polymer matrix binding various short or continuous fibers. They are designed to distribute loads between fibers through the matrix, providing several benefits, including outstanding strength in the direction of reinforcements, high stiffness, and light weight. Additional benefits include excellent abrasion and corrosion resistance. The purpose of this article is to identify the ideal wear testing parameters for PMCs. The composite materials studied were fabricated using polymethyl methacrylate (PMMA) and 5% nano B4C through injection molding. In order to determine the most effective parameters, the article concentrates on determining the friction rate and coefficient. The findings of this study can be applied to the wear area of automotive components
