  • Publication number: 20170275458
    Abstract: Disclosed are a polyamide resin composition comprising a fiber reinforced polyamide pellet, a molded article comprising the polyamide resin composition and a method of manufacturing the molded article. The polyamide resin composition includes the fiber reinforced polyamide pellet, which can be produced by pultrusion, such that moldability and mechanical properties of molded articles may be sufficient using the recycled polyamide 66 resin. In addition, although the polyamide resin composition contains a less amount of inorganic substance, mechanical properties of the molded article are sufficient, weight of molded articles can be reduced and production costs can be reduced.
