METHOD FOR WINDING FILAMENT AND PRESSURE VESSEL MANUFACTURED THEREBY

WIPO Patent Application WO/2022/260289

A1

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.
