Carbon Fibre Reinforced Polypropylene: An Electrical Conductivity Model

Abstract:

This Extrusion permit in controlling electrical conductivity before composite materials undergo the manufacturing process. However, studies on electrical conductivity in high conductive polymer composite materials are still in preliminary stage. Thus, the studies on electrical conductivity model are crucial as it able in predicting the electrical conductivity hence minimizing the experimental conducted. In this study, conductivity model was conducted to validate the series of experiment. The electrical conductivity increases as shear rate decrease and the highest electrical conductivity of 3 S/cm is obtained which indicated that the shear rate is crucial in increasing the electrical conductivity of the composites compared to extrusion temperature hence it is consider in the modelling.
