Abstract

The extrusion process is one of the pre-mixing processes that aid in improving the filler dispersion in conductive polymer composite (CPC). Electrical conductivity level still needs much improvement in mixing process through mechanical mixer. This study was conducted to optimise the extrusion process parameters (temperature and rotational speed) of milled carbon fibre (MCF) and polypropylene (PP) using experimental design (Taguchi method). Orthogonal array design of L9is adapted in this study to determine the optimum level and measuring performance via variance analysis to obtain the maximum electrical conductivity. The optimum working conditions for 80 wt. % of MCF and 20 wt. % of PP composition were determined at the extrusion temperature of 230°C to 250°C and a rotational speed of 50 to 90 rpm in which the electrical conductivity increases to the maximum value of 3.67 S/cm. Optimisation of these parameters is expected to produce a robust design with improved electrical conductivity and mechanical properties.
