Official abstract text for this publication.
A method for manufacturing a pressure vessel includes blow-molding a liner vessel in a shape having at least one bulkhead and two or more separated spaces and inserting a bulkhead reinforcing plate between the separated spaces. The method further includes forming an outer layer comprising a glass fiber or a glass fiber-carbon fiber composite material on the outside of the liner vessel and forming at least one anchor site configured to couple the bulkhead reinforcing plate to the outer layer.
Opening claim text (preview).
What is claimed is: 1 . A method for manufacturing a pressure vessel, the method comprising: blow-molding a liner vessel in a shape having at least one bulkhead and two or more separated spaces; inserting a bulkhead reinforcing plate between the separated spaces; forming an outer layer comprising a glass fiber or a glass fiber-carbon fiber composite material on the outside of the liner vessel; and forming at least one anchor site configured to couple the bulkhead reinforcing plate to the outer layer. 2 . The method of claim 1 , wherein the bulkhead reinforcing plate is made of a thermoplastic carbon fiber composite material. 3 . The method of claim 1 , wherein the step of forming the outer layer comprises applying a filament winding. 4 . The method of claim 1 , wherein the liner vessel comprises Polyamide 6 material having low gas permeability. 5 . The method of claim 1 , wherein the bulkhead reinforcing plate is configured to be separated into left and right sides or upper and lower sides and to be fastened to the at least one bulkhead of the liner vessel from the left and right sides or the upper and lower sides. 6 . The method of claim 1 , wherein in the step of forming the at least one anchor site, the anchor site is manufactured separately from the bulkhead reinforcing plate. 7 . The method of claim 1 , wherein in the step of forming the at least one anchor site, the at least one anchor site is formed integrally with the bulkhead reinforcing plate. 8 . The method of claim 7 , wherein the at least one anchor site is protrusion-molded. 9 . The method of claim 1 , wherein the at least one anchor site includes two or four anchor sites formed at symmetric positions. 10 . A pressure vessel comprising: a liner vessel made of a plastic material having at least one bulkhead and two or more separated spaces; a bulkhead reinforcing plate configured to reinforce the at least one bulkhead of the liner vessel by being inserted between the separated spaces of the liner vessel; an outer layer comprising a glass fiber or a glass fiber-carbon fiber composite material, the outer layer formed on the outside of the liner vessel; and at least one anchor site provided at an outer surface of the outer layer and the bulkhead reinforcing plate and is configured to prevent the bulkhead reinforcing plate from being substantially displaced due to pressure. 11 . The pressure vessel of claim 10 , wherein the at least one anchor site is manufactured separately from the bulkhead reinforcing plate. 12 . The pressure vessel of claim 10 , wherein the at least one anchor site is formed integrally with the bulkhead reinforcing plate. 13 . The pressure vessel of claim 12 , wherein the at least one anchor site is protrusion-molded. 14 . The pressure vessel of claim 10 , wherein the at least one anchor site includes two or four anchor sites formed at symmetric positions. 15 . The pressure vessel of claim 10 , wherein the bulkhead reinforcing plate comprises a thermoplastic carbon fiber composite material. 16 . The pressure vessel of claim 10 , wherein the outer layer is formed on the outside of the liner vessel by applying filament-winding. 17 . The method of claim 10 , wherein the liner vessel comprises Polyamide 6 material having low gas permeability. 18 . A vehicle comprising the pressure vessel of claim 6 .
