Patent number: 9868253Abstract: A method of manufacturing a tank comprises providing a covered liner by winding a fiber impregnated with a thermosetting resin on a liner; and performing a heat curing process that cures the thermosetting resin by heating the covered liner in a heating furnace. The heat curing process comprises controlling the heating to prevent temperature of the thermosetting resin that is changed by the heating from exceeding a heat resistant temperature of the liner.Type: GrantFiled: July 11, 2014Date of Patent: January 16, 2018Assignee: Toyota Jidosha Kabushiki KaishaInventor: Sakuma Emori

Patent number: 9802367Abstract: Fiber composite components can be formed by winding fibers along tracks of a winding spool of a winding core. The fibers may either be pre-coated with a curable resin, or the curable resin may be applied to the fibers after the fibers are wound along the tracks of the winding spool of the winding core. The curable resin may also and/or alternatively be applied to a mold that receives the fibers wound about the winding spool. The curable resin may then be cured, after which the winding spool and the winding core may be removed in order to release the fiber composite component. In some cases, the winding spool may be removed from the fiber composite component by moving the winding spool inwardly towards an inside of the winding core.Type: GrantFiled: May 22, 2014Date of Patent: October 31, 2017Assignee: THYSSENKRUPP PRESTA AGInventors: Thomas Heitz, Sebastian Regner, Arne Schacht

Patent number: 9718233Abstract: A method for manufacturing a fiber layer or a component perform includes yieldably tensioning a plurality of yarns in a tensioning plane such that each yarn is separately and individually held in a yieldable manner. Then, a workpiece carrier is moved through the tensioning plane in a perpendicular direction thereto such that the yarns contact the workpiece carrier and respectively bend according to the contour of the workpiece carrier. If a predetermined tensile force on one or more of the plurality of yarns is exceeded, then an additional length of such yarn(s) is supplied from a reserve and/or a coil to cover the workpiece carrier. Then, the ends of the yarns are fixed along an edge of the workpiece carrier.Type: GrantFiled: March 30, 2012Date of Patent: August 1, 2017Assignee: COMPOSITENCE GMBHInventors: Ingo Karb, Volker Witzel

Turbine engine part forming a compressor stator or a turbine nozzle, and method for fabricating same
Patent number: 9708917Abstract: A turbine engine part forming a compressor stator or a turbine nozzle and including an inner shroud, an outer shroud, and vanes extending substantially radially between the inner and outer shrouds and being secured thereto. The part is made of composite material and is obtained by densifying a fiber preform with a matrix. The fiber preform includes a set of yarns extending continuously along a path passing longitudinally along the preform portions of at least two consecutive vanes by passing through the inner shroud preform portion and the outer shroud preform portion, and the woven fiber reinforcement yarns extends continuously in the circumferential direction along an inner shroud segment and along an outer shroud segment between which the consecutive vanes extend.Type: GrantFiled: June 20, 2012Date of Patent: July 18, 2017Assignee: SNECMAInventors: Olivier Belmonte, Julien Foll -
Patent number: 9691512Abstract: A chopper disc for a device for the processing of neutron beams is made of carbon fibers and has a concentric, hollow cylindrical recess for receiving a hub for connection to a pivot bearing. The chopper disc also includes a concentric absorber area for absorbing neutrons striking the chopper disc and at least one window in the absorber area through which neutrons of the neutron beam can pass. The carbon fibers extend from the outer periphery of the chopper disc radially in the direction of the recess and contact the recess tangentially.Type: GrantFiled: April 1, 2015Date of Patent: June 27, 2017Assignee: Airbus DS GmbHInventors: Berno Spiegelhalder, Uwe Keller, Ernst Kaeppeler

Patent number: 9676149Abstract: A steering-column assembly for a motor vehicle may include a steering spindle rotatably mounted in a steering-column tube, which steering-column tube is mounted in a console that connects the steering-column directly or indirectly to a body of the motor vehicle. At least one of the components of the steering-column, such as the console, for example, may include a fiber composite component that can be formed by winding fibers along tracks of a winding spool of a winding core, introducing a curable resin into the fibers or a mold to be used with the wound fibers, curing the wound fibers, and removing the winding spool and the winding core so as to release the fiber composite component. The fiber composite component may then be fitted into the steering column assembly.Type: GrantFiled: March 17, 2014Date of Patent: June 13, 2017Assignee: THYSSENKRUPP PRESTA AGInventors: Thomas Heitz, Sebastian Regner, Arne Schacht
