Publication number: 20130299505Abstract: A step of forming a low-angle helical layer on an outer surface of at least part of each liner dome portion and an outer surface of a liner cylindrical portion, a step of forming an inner hoop layer on an outer surface of the low-angle helical layer on the liner cylindrical portion, and a step of forming a mixed layer by alternately laminating a low-angle helical layer and an outer hoop layer on an outer surface of the inner hoop layer and low-angle helical layer on each liner dome portion. Then, on the liner cylindrical portion, 90% or more of the sum of the thickness of the inner hoop layer and the thickness of the outer hoop layer in the mixed layer is arranged within the range of 75% of the fiber reinforced plastics layer adjacent to the liner in a thickness direction of the fiber reinforced plastics layer.Type: ApplicationFiled: January 19, 2012Publication date: November 14, 2013Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Hirokazu Otsubo, Shiro Nishibu

Publication number: 20130153583Abstract: The disclosure provides a pressure vessel for storing a fluid, comprising an outer jacket applied to a plastic core container, the outer jacket comprising a first fibre-reinforced reinforcing device with one or several wound layers comprising first fibres that are embedded in a first matrix material, a second fibre-reinforced reinforcing device formed on the outside of the first device and with one or several wound layers comprising second fibres that are embedded in a second matrix material, and an impact-absorbing thickening of the outer jacket in a polar cap region of the plastic core container. The thickening is formed in that one or several wound layers that are thickened in the polar region are formed in at least one of the reinforcing devices with a face opening that is larger than a face opening of other non-thickened wound layers in at least one of the reinforcing devices.Type: ApplicationFiled: June 17, 2011Publication date: June 20, 2013Applicant: XPERION GMBHInventors: Michael Kleschinski, Dietmar Muller

Patent number: 8464893Abstract: A pressure container has an inner shell with a pair of fittings and a reinforcement layer formed around the inner shell, and is configured so that a reinforcement member is attachable to the pair of fittings in a process of forming the reinforcement layer and a functional component which performs a predetermined function is also attachable to the fittings. This can allow the reinforcement member to prevent expanding deformation of the pressure container in production of the pressure container, and can ensure effective use of openings after removal of the reinforcement member.Type: GrantFiled: June 6, 2006Date of Patent: June 18, 2013Assignee: Toyota Jidosha Kabushiki KaishaInventors: Yasuyuki Iida, Natsuhiko Katahira, Koichi Takeuchi

Patent number: 8317056Abstract: A structure and method for bonding heat-insulating protection walls of a liquefied natural gas carrier is provided. Each of the heat-insulating protection walls is formed of an insulation foam layer and a fiber-reinforced composite reinforcing sheet attached to a surface of the insulation foam layer. The heat-insulating protection walls are provided in a tank of the liquefied natural gas carrier in a mutually adjoining relationship and bonded to one another at a junction to keep the tank cold. The structure includes a fiber-reinforced composite joint sheet positioned in alignment with the juncture of the heat-insulating protection walls and bonded to the fiber-reinforced composite reinforcing sheet by an adhesive agent and a spacer interposed between the fiber-reinforced composite reinforcing sheet and the fiber-reinforced composite joint sheet for keeping the adhesive agent uniform in thickness.Type: GrantFiled: July 12, 2007Date of Patent: November 27, 2012Assignee: Korea Advanced Institute of Science and TechnologyInventors: Dai-Gil Lee, Sang-Wook Park, Byung-Chul Kim, Seong-su Kim
