20130330832 | METHOD AND SYSTEM FOR LEAK DETECTION IN VACUUM BAGGING - A material for use in vacuum bagging a component. The material includes a compound sensitive to moisture, such that an exposure of the compound to moisture or wetting causes a physical and/or chemical change in the compound that is visually detectable in the cover material. A method of leak detection during vacuum bagging involves the steps of: arranging a component in a vacuum bagging assembly, such as to form a fibre-reinforced plastic component; arranging a material according to the invention in the vacuum bagging assembly such that the compound sensitive to wetting or moisture is under, or on an inner side of, a sealing film or vacuum bag of the assembly; applying a vacuum to the vacuum bagging assembly to evacuate a space containing the component and sealed by the sealing film or vacuum bag; and wetting an outer surface of the sealing film or vacuum bag. | 12-12-2013 |
20140084508 | METHOD AND DEVICE FOR PRODUCING A FIBRE COMPOSITE COMPONENT - The present invention provides a method for producing a fibre composite component, comprising: arranging a first and a second mould in relation to one another in such a way that these together form a first cavity; laying a fibre material on the first and/or second mould; filling the formed first cavity with a casting material and solidifying said casting material in order to seal the first and the second mould to one another and/or interconnect them; and infiltrating the fibre material with a matrix and curing said matrix to form the fibre composite component. | 03-27-2014 |
20140087143 | Method for producing a structural component, and structural component - A method for manufacturing a structural assembly comprising at least two assembly components interconnected by means of a thermoplastic plastics material, and useful in the field of aviation or space travel. First, a first assembly component and a second assembly component are provided and arranged so as to form an arrangement. Second, the arrangement is subjected to creep forming at a temperature which is selected in such a way that the thermoplastic plastics material melts at least in part during the creep forming so as to connect the first assembly component and the second assembly component. The invention further relates to structural assemblies, in particular for an aircraft or spacecraft, and to an aircraft or spacecraft comprising a structural assembly of this type. | 03-27-2014 |

20130118770 | Method for the automated manufacture of a fibre composite component with integrated lightning protection, and also a fibre composite component - A method for manufacturing a fiber composite plastic component with integrated lightning protection. The steps include, for a positive mold, automatically laying down a ribbon-form pre-preg material or dry ribbon-form reinforcing fiber strands onto the mold. Then, automatically laying down a ribbon-form lightning protection material onto the pre-preg material or the reinforcing fiber strands. For a negative mold, the steps include automatically laying down the lightning protection material on the negative mold, then automatically laying down the pre-preg material or the dry reinforcing fiber strands onto the positioned lightning protection material. The method also includes curing the laminate construction formed with the pre-preg material and the lightning protection material to form the fiber composite component, or infiltrating the dry reinforcing fiber strands with a plastic, and subsequently curing the laminate construction formed with the infiltrated reinforcing fiber strands and the lightning protection material to form the fiber composite component. | 05-16-2013 |
20150060437 | Active Temperature Control for Induction Heating - An induction heating system and a method for controlling a process temperature for induction heating of a workpiece. The induction heating system comprises an inductor configured to generate an alternating magnetic field in response to an alternating current supplied thereto, a magnetic load comprising a magnetic material, the magnetic material having a Curie temperature and being configured to generate heat in response to the alternating magnetic field being applied thereto, the magnetic load being connectable to the workpiece in a heat-conducting manner so as to transfer the generated heat to the workpiece, and a control unit configured to control the process temperature for manufacturing the workpiece by adjusting the alternating magnetic field when the temperature of the magnetic material is in a temperature control range around or below the Curie temperature of the magnetic material, the temperature control range being dependent on the magnetic material of the magnetic load. | 03-05-2015 |
