Fabrication and Characterization of Carbon Black and Phenol Formaldehyde Composites

Abstract

Carbon black and Phenol formaldehyde composites were prepared by hot press molding at different temperature (180°C, 200°C, 220°C); pressure (100 kN, 150 kN, 200 kN, 250 kN); heating time (10 min, 20 min, 30 min, 60 min) and several compositions (50%C, 60%C, 70%C, 80%C, 90%C). The different properties such as physical, mechanical, thermal properties were studied by Universal Testing Machine (UTM), Micro hardness tester, TGA/DTA analyser and X-Ray diffractometer etc. In this work, it was observed that the bulk density was slightly changed for 50% carbon black and Phenol formaldehyde composites. Compressive strength of sample was increased with increasing the pressure, heating temperature and time.
