Abstract

A composite material is a combination of two or more materials that have advantages such as being lightweight, higher strength, corrosion resistance, and low installation cost [1]. Composite materials are commonly found in aircraft, automotive, manufacturing, and other industries [2,4]. Composite materials based on the type of reinforcement consist of types of fibers, particles, and structures [5-14]. In this study, the particle composite material is made from a reinforcing powder made from liquid waste and used for the manufacture of motor vehicle body products (wing or bottom components). Composite reinforcing materials from liquid waste are obtained through the process of drying palm liquid waste or rubber in powder form. The manufacturing process of two-wheeled motor vehicle body products uses a casting process by making molds and products using the hand-laying coating method. The alloying material used in this research is Yukalac 156 BQTN-EC resin and reinforcement from liquid palm oil or rubber waste powder. The variation of the alloy becomes a parameter to evaluate the quality of the casting product analyzed in the form of the geometric characteristics of the product i.e. the dimensions and surface roughness. Variations of composite material alloys use a ratio of 1:1 to 5:1. From the results of the study, it is found that the dimensions are close to the design value with the smallest deviation at a composition ratio of 3:1 which surface roughness values is 2.18 to 3.13 µm for mold dies and 6.45 to 8.02 µm for the product.
