Preliminary study on the physical properties of palm ash and PCB waste mixed with phenolic resin.

Abstract

Brake pad is widely used in automotive industry and consists of various materials including asbestos which is harmful to the human and its production exceeds 10 or more ingredients. In this work, preliminary investigation on possibility to use combination palm ash and PCB waste was carried out in order to reduce harmful materials in brake pad and pollutions. Characterization of palm ash and PCB was done by using XRF, Malvern Particle size and Scanning Electron Microscopy (SEM). The composition palm ash and PCB waste was prepared by pre-mix the palm ash, PCB waste and aluminum powder with phenolic resins in ball mill and then compressed at 122 MPa. Samples were cured at temperature 150°C for 5 minutes. Microstructure, density and porosity, water absorption and compressive test were carried out on the specimens.
