The present invention provides a method for winding a filament comprising the steps of: (a) winding a fiber-reinforced composite on the outer circumferential surface of a liner to form a first pattern layer; (b) winding the fiber-reinforced composite on the upper surface of the first pattern layer to form a second pattern layer, thereby forming a first composite layer; and (c) forming a first pattern layer again on the upper surface of the first composite layer, and forming a second pattern layer on the upper surface of the first pattern layer to form a second composite layer, wherein the composite layer is repeatedly formed according to Equation 1: [Equation 1] CN ≤ 5, where CN is the number of all the composite layers. La présente invention concerne un procédé d'enroulement d'un filament comprenant les étapes consistant : (A) à enrouler un composite renforcé par des fibres sur la surface circonférentielle externe d'un revêtement interne pour former une première couche de motif ; (b) à enrouler le composite renforcé par des fibres sur la surface supérieure de la première couche de motif pour former une seconde couche de motif, formant ainsi une première couche composite ; et (c) à former une première couche de motif à nouveau sur la surface supérieure de la première couche composite, et à former une seconde couche de motif sur la surface supérieure de la première couche de motif pour former une seconde couche composite, la couche composite étant formée de façon répétée selon l'équation 1 : [Équation 1] CN ≤ 5, où CN est le nombre de toutes les couches composites. 본 발명은 (a) 라이너의 외주면에 섬유강화 복합재를 와인딩하여 제1패턴층을 형성하는 단계; (b) 상기 제1패턴층 상부면에 섬유강화 복합재를 와인딩하여 제2패턴층을 형성하여 제1복합재층을 형성하는 단계; 및 (c) 상기 제1복합재층 상부면에 다시 제1패턴층을 형성하고, 상기 제1패턴층 상부면에 제2패턴층을 형성하여 제2복합재층을 형성하는 단계를 포함하며, 하기 수학식 1에 따라 복합재층이 반복 형성되는 것을 특징으로 하는 필라멘트 와인딩 방법을 제공한다: [수학식 1] CN ≤ 5 여기서 CN는 전체 복합재층의 개수임.
