Abstract
A long carbon fiber reinforced thermoplastic resin composition for foam injection and a molded article manufactured using the same are provided. More particularly, the thermoplastic resin composition and the manufactured molded article may be capable of improving component assembly and stability by minimizing deformation after foam injection molding. Such composition and molded article can be utilized as a component for a vehicle structure such as a panoramic sunroof frame. Also provided herein is a low-density polyamide-6 polymer comprising a long carbon fiber reinforcing agent, a thermoplastic elastomer, a silane-based coupling agent and a sodium phosphate nucleating. The polymer is suitable for foam injection. The thermoplastic resin composition and molded article made of said composition are light weight and economic feasibility as well as having high stiffness, durability, dimensional stability, and a desirable injection appearance.
