Effect of Fiber Side-Feeding on Various Properties of Nickel-Coated Carbon-Fiber-Reinforced Polyamide 6 Composites Prepared by a Twin-Screw Extrusion Process

In the present study, how side-feeding of NiCF during twin-screw extrusion processing influences fiber aspect ratio and thermal, mechanical, electrical, electromagnetic properties nickel-coated carbon (NiCF)-reinforced polyamide 6 (PA6) composites was explored. For this, length distribution, thermal stability, heat deflection temperature, dynamic mechanical property, tensile, flexural, electrical resistivity, interference shielding effectiveness (EMI SE) NiCF/PA6 were extensively investigated. Chopped regularly fed via either a main feeder or side pellets with different fiber-feeding pathways prepared. The effect on distribution composite studied. storage modulus, surface EMI SE strongly depended not only content but also feeding method (main-feeding side-feeding) upon processing, indicating that relevant to critically important enhance composites’ properties. As result, produced exhibited an longer than main-feeding, leading enhancement properties, depending content.
