Generally, Carbon fiber reinforced polymers are high strength, high elasticity and lightweight materials. So many researches have been conducted on carbon fiber reinforced composites in the aircrafts and automobiles industries. In particular, This composites had a lot of advantages of high speed forming and easy postprocessing. However, there is a poor compatibility between carbon fiber and thermoplastic polymers. To solve this problems, there are so many methods such as surface treatment of carbon fiber and using proper additives. This study inform the mechanical properties between Polyamide6 and surface sizing treatment type of carbon fiber. And physical properties were compared using dendritic polymer which gives free volume within the polymer matrix. Experimentals were performed by twin screw extruder and screw configuration were designed best combination for mixing efficiency between matrix and additives.
