The present invention provides a high strength polymer composite comprising a thermoplastic polymer and a carbon nanotube, wherein a BET specific surface area is 40 m2/g to 120 m2/g, a bulk density is 10 to 60 kg/m3, and the content of the carbon nanotube relative to the total weight of the polymer composite is 5 to 15 wt%. The present invention provides a high strength polymer composite with improved mechanical strength by adjusting and optimizing the specific surface area and bulk density together, thereby increasing the content of the carbon nanotube contained inside the polymer composite without deteriorating the dispersibility of the carbon nanotube. La présente invention concerne un composite polymère à haute résistance comprenant un polymère thermoplastique et un nanotube de carbone. Une surface spécifique BET est de 40 m2/g à 120 m2/g, une masse volumique apparente est de 10 à 60 kg/m3, et la teneur du nanotube de carbone par rapport au poids total du composite polymère est de 5 à 15 % en poids. La présente invention concerne un composite polymère à haute résistance présentant une résistance mécanique améliorée par réglage et optimisation de la surface spécifique et de la masse volumique apparente ensemble, ce qui permet d'augmenter la teneur du nanotube de carbone contenu à l'intérieur du composite polymère sans détériorer la dispersibilité du nanotube de carbone. 본 발명은 열가소성 고분자; 및 카본나노튜블 포함하는 고분자 복합재에 있어서, BET 비표면적이 40 m2/g 내지 120 m2/g 이고, 벌크밀도가 10 내지 60kg/m3 이며, 복합재 총 중량 대비 카본나노튜브의 함량이 5 내지 15중량%인 고강도 고분자 복합재를 제공하며, 비표면적 및 벌크밀도를 함께 조절하여 최적화 시킴으로써, 카본나노튜브의 분산성 저하 없이 고분자 복합재 내에 포함되는 카본나노튜브의 함량을 증가시킬 수 있음으로써, 보다 기계적 강도가 향상된 고강도 고분자 복합재를 제공한다.
