MECHANICAL AND THERMAL PROPERTIES OF INJECTION MOLDED LONG GLASS FIBER REINFORCED RUBBER TOUGHENED POLYAMIDE 6 COMPOSITE

Abstract

Long glass fiber reinforced Nylon 6/Amine Terminated Butadiene Acrylonitrile (ATBN) block copolymer pellets were prepared by a pultrusion process. Optical microscope (OM) and scanning electron microscope (SEM) showed that the fiber dispersion and fiber-matrix bonding in the injection molded long glass fiber reinforced Nylon 6/ATBN block copolymer pellets are better than that from the conventional melt pelletized process. The fiber length distribution in the molded samples was calculated by image analyzer. The static tensile strength, tensile modulus, flexural strength, flexural modulus, notched Izod impact and heat deflection temperature (HDT) of injection molded long glass fiber reinforced Nylon 6/ATBN composites are superior to those of the short fiber reinforced Nylon 6 composites. Moreover, the effect of acrylonitride content on the degradation temperature of injection molded long glass fiber reinforced Nylon 6/ATBN composites was studied.
