EFFECTS OF REPROCESSING ON THE FIBER LENGTH AND MECHANICAL PROPERTIES OF NYLON-6 / GLASS FIBER COMPOSITES

摘要

Nylon-6 pellets were compounded with glass fibers in a twin-screw extruder and the resulting pellets were reprocessed for four times through twin-screw extrusion, Collected samples were injection molded and izod impact and tensile tests were performed. Also, fiber length distribution curves were obtained. Results showed that beyond a certain length, fiber attrition is almost stopped and the mechanical properties reach asymptotically low values.
