Patent number: 10457000Abstract: A flow aid for an infusion structure for infiltrating fiber material with resin to produce a fiber composite component includes a resin-impermeable upper layer and a lower layer which are joined together in a peripheral region of the flow aid and provide a flow space between the two layers. The lower layer provides an outlet for discharging resin out of the flow aid into an interior of the infusion structure. The flow aid includes an inlet for feeding the resin into the flow space, thereby facilitating uniform distribution of the resin over all of the fiber material.Type: GrantFiled: April 22, 2014Date of Patent: October 29, 2019Assignee: Airbus Defence and Space GmbHInventors: Juergen Filsinger, Michael Steinhilber

Method for producing multilayer tailored fiber placement (TFP) preforms using meltable fixing fibers
Patent number: 7942993Abstract: In a method, multilayer tailored fiber placement (TFP) preforms of any desired thickness may be easily produced without fixing threads or intermediate layers interfering. Reinforcing fibers are sewn onto a substrate using a chemically or thermally meltable fixing thread thus resulting in the formation of a reinforcing fiber structure. The fixing thread firstly serves to fix the reinforcing fibers on the substrate and is subsequently melted so that the fixing thread disintegrates while pre-fixing the reinforcing fibers and may not influence the mechanical properties of the reinforcing fiber structure.Type: GrantFiled: December 10, 2001Date of Patent: May 17, 2011Assignee: EADS Deutschland GmbHInventors: Andreas Gessler, Juergen Filsinger -

Patent number: 7507446Abstract: A ready-made technical process for manufacturing fiber-reinforced plastic building components envisions the use of a link and, optionally, a flange and/or a base using textile blanks as starting material. Initially, at least two layers of the textile blanks are positioned vis-à-vis one another, clamped in and undergo a first sewing-up process. A preform is fashioned featuring the architecture of the product that is to be manufactured, and subsequently the preform is infiltrated with resin in order to realize the plastic building component. A tension module realizes a flange on a textile preform and a sewing material holder receives a textile preform in order to implement the steps referred to.Type: GrantFiled: January 31, 2006Date of Patent: March 24, 2009Assignee: Eads Deutschland GmbHInventors: Thomas Koerwien, Ernst-Joachim Bauer, Juergen Filsinger

Patent number: 6890470Abstract: A fiber composite structural component such as a fitting, bracket, mounting or the like is produced by applying fiber material such as fiber threads or fiber yarns in an automatic circular weaving operation to a core that has at least two sections, to form a fiber material body (6). One core section is removed from the fiber material body when the weaving is completed. The body is then deformed in a mold that has the contour of the finished structural component with at least one mold core section still in the fiber material body. The deformed configuration of the structural component is then impregnated in an RTM device with a resin and hardener followed by curing. Reinforcements may be inserted or secured to the fiber material body prior to the impregnated and curing step.Type: GrantFiled: March 10, 2003Date of Patent: May 10, 2005Assignee: Airbus Deutschland GmbHInventors: Martin Staub, Tim Leeraar, Juergen Filsinger, Andreas Gessler

Patent number: 6843953Abstract: In a method for producing fiber-reinforced plastic components made of dry fiber composite preforms by an injection method for injecting matrix material, the arrangement of the fiber composite preform on one surface of the preform resulting in a flow promoting device, on a tool, creates a first space by a gas-permeable and matrix-material-impermeable membrane surrounding the preforms. Formation of a second space arranged between the first space and the surroundings by a foil, which is impermeable to gaseous material and matrix material, is provided, with removal by suction, of air from the second space resulting in matrix material being sucked from a reservoir into the evacuated first space and with the flow promoting device causing distribution of the matrix material above the surface of the preform facing the flow promoting device, thus causing the matrix material to penetrate the preform vertically.Type: GrantFiled: March 13, 2001Date of Patent: January 18, 2005Assignee: EADS Deutschland GmbHInventors: Jürgen Filsinger, Torsten Lorenz, Franz Stadler, Stefan Utecht
