The present invention relates to a filament winding method and a pressure vessel manufactured thereby. The method comprises the steps of: (a) forming a first pattern layer by winding a fiber-reinforced composite on an outer circumferential surface of a liner; (b) forming a second pattern layer by winding a fiber-reinforced composite material on an upper surface of the first pattern layer to form a first composite material layer; and (c) forming a first pattern layer on an upper surface of the first composite material layer and forming a second pattern layer on an upper surface of the first composite material layer to form a second composite material layer, wherein the composite material layer is repeatedly formed according to equation 1 below. [Equation 1] C_N =< 5, where C_N is the total number of composite layers. The present invention is to increase the durability of a pressure vessel. 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.
