Abstract:
1. A method of manufacturing a corrugated preform using a braiding process, comprising: braiding a composite material corresponding to an outer diameter of a cylindrical cylinder shape; braiding the composite material by connecting a plurality of separate composite materials to one side of the braided composite material; and braiding the composite material to one side of the separate composite material corresponding to the outer diameter of the cylindrical cylinder shape, wherein the braiding the composite material corresponding to an outer diameter of a cylindrical cylinder shape and the braiding the composite material to one side of the separate composite material corresponding to the outer diameter of the cylindrical cylinder shape are applied to a process of manufacturing a concave portion of the corrugated preform, wherein the concave portion of the corrugated preform is braided in the process while rotating an equipment plate in a predetermined direction.
