Abstract

Depletion of fossil fuels and greenhouse gases is an essential issue in the development of the automotive industry. From the design stage, material selection becomes the most crucial factor. Therefore, this article discusses the development of lightweight automotive materials for increasing fuel efficiency and reducing carbon emissions. Material reliability is assessed by how much weight reduction can be achieved, production costs, safety and durability. Ferro materials (mild steel, High Strength Steel, and Advanced High Strength Steel), non-ferrous (aluminium and magnesium alloy), and Fiber Reinforced Plastics (FRP) have been proven to reduce the total weight of vehicles up to 12.6%. Confirmation of statistical data from the literature illustrates the possibility of using lightweight material to achieve zero CO2 emission. In addition, the 12.6% weight reduction still meets the vehicle safety factor.

Abstract

Currently, research on natural fiber composites (NFC) for automotive applications has attracted the attention of researchers and academics. Natural fibers such as coconut fiber and wood powder are mixed with metal materials such as aluminum and copper to obtain the composite characteristics of automatic motorcycle clutch pad materials. Coconut fiber and wood powder are suitable natural materials for composites and are easily obtained from waste. Natural fiber materials with metal reinforcement into composites are expected to produce materials suitable for friction materials such as clutch pads and brake pads with a good characteristic. This study aims to determine the characteristics of the coefficient of friction, wear, and hardness of NFC materials reinforced aluminum and copper powder for the performance of automatic motorcycle clutch pads. Experiments were carried out on various compositions of aluminum and copper powder. Tribometer testing was carried out to determine the friction coefficient and wear. Hardness testing using the Vickers method and testing the performance of automatic motorbikes with a chassis dyno test. The results show that the performances of the clutch pad with NFC-reinforced aluminum and copper show power and torque results that resemble the performances of genuine part materials in each operating cycle. The value of friction coefficient, wear, and hardness of this material are a value close to that of a genuine part clutch pad material. The improved performance of this material is expected to be considered in the manufacture of future clutch pads.

Abstract

The use of composite materials in brake pads is becoming increasingly popular due to their high-performance characteristics, including good thermal stability, high wear resistance, and low noise generation. However, the development of new composite materials that offer even better performance is still an ongoing research area. In this study, the composite was made by hand layup method using epoxy resin as matrix material, with rice husk, Al2O3, and Fe2O3 as reinforcing materials. The composition of the composites was varied by changing the percentage of the reinforcement materials. The composites were then subjected to several characterization tests, including density, hardness, flexural strength, thermal analysis, Scanning Electron Microscopy (SEM), TGA/DSC, and wear testing. The test results showed that additional reinforcement materials to the epoxy resin matrix improved the mechanical properties of the composites. Overall, the study demonstrates that a hand layup method is a viable approach for preparing brake pad composite materials and that the addition of rice husk, Al2O3, and Fe2O3 can improve the mechanical properties of the composites. The best properties produced in this research were found in one of the specimens which used epoxy, rice husk, Al2O3, and Fe2O3 with a composition of 50 wt.%, 20 wt.%, 15 wt.%, and 15 wt.%. However, the addition of rice husk also provides wear resistance and thermal stability. This study contributes to the Sustainable Development Goals (SDGs) by advancing innovation, promoting sustainability, and reducing emissions in automotive industry applications.
