The improvement of wear resistance is very important in the thermoplastic composite wear application, therefore the present work focused on this property by adding short carbon fibers( 5 , 10 , 15 and 20 wt %)to reinforced polyamide6,6(Pa6,6). Twin screw extruder is used to prepared the composite specimens .The results obtained from this study improved wear resistance for only (15 and 20 wt%) and Improved the mechanical properties tensile strength, modulus and hardness with increased carbon fibers content
