Analisis keausan dan kekerasan kampas rem terbuat dari serat daun nanas yang di arangkan dengan resin epoxy

Abstract

Over time, the automotive industry continues to increase with increasing demand for transportation equipment, especially for motorized vehicles. One of the most important parts of a motor vehicle is the braking system. In the braking system, the brake lining is a component part that directly rubs against the rotating part, namely the drum (drum system) or disk (disc system). Material developments to date continue to develop rapidly. This development is due to the need for materials that are heat resistant, resistant to water, friction, and so on. This depends on the use and needs of the material itself. According to (Silvia et al., 2022) the third specimen received a score of 71.3 HD. So the higher the temperature, the lower the hardness of the specimen. Based on research that has been carried out on the composite brake lining material of pineapple leaf fiber and epoxy resin, the following conclusions can be drawn: 1. It can be concluded that the pyrolysis temperature greatly influences the mechanical properties of the brake lining, from the results of the hardness test at a temperature of 300°C, the hardness results were obtained. The highest is with an average value of 85.1 HD, while at a temperature of 450°C it only gets an average value of 72.2 HD. In this SEM test, it was taken from the best wear test, namely a temperature of 450°C. From several images in the SEM test, it can be concluded that there are several air cavities due to the pressing process being less than optimal, on the other side of the sample there is epoxy resin which is lumpy due to poor mixing. not evenly distributed. Adding temperature variations to get better brake lining results. 3. For further research, you can add other tests such as proximate tests and several other tests.
