Mechanical Characteristics and Microstructure of Natural Fiber Composite Material with Aluminum-reinforced for Automatic Clutch Pads

Abstract

This study investigates the mechanical properties and microstructure of a novel composite material designed for automatic clutch pads. The natural fiber composite (NFC) consists of coconut fiber and wood powder reinforced with aluminum powder, aiming to increase strength. A series of experimental analyses, including tensile testing, compressive testing, hardness measurement, and microstructural examination, were conducted to thoroughly evaluate the composite. The results indicate a significant improvement in mechanical strength compared to commercial clutch pad materials. Additionally, scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS) analysis shows the distribution and interaction of natural fibers and aluminum powder within the composite matrix, shedding light on the reinforcement mechanisms. The tensile strength, compressive strength, elastic modulus, and hardness values increase with aluminum composition from 0 to 15%. However, at 20% composition, a decrease was observed. This research provides valuable insights into the development of high-performance natural composite materials for automatic clutch pads.
