A joining method and assembly for an aircraft. To improve the characteristics or permit hitherto impossible connections between thermoplastic and thermoset components, a multi-material joining method is disclosed in which a thermoplastic connecting region is formed on the thermoplastic component. The connecting region is connected to the thermoset component by interdiffusion. For this purpose, the uncured second component is brought into contact with the connecting region and heat is supplied. An interdiffusion layer is formed which fixedly connects the second component and the connecting region to one another and thus joins the first component to the second component.

A tooling for use in a method for electromagnetic welding of two contacted surfaces of molded parts. The tooling includes a rubber body and pressurizing means for pressurizing the rubber body and applying pressure to the contacted surfaces. The rubber body includes an embedded stiff body shaped such as to define different rubber body thicknesses in different directions, which causes a different pressure build-up in the different directions. A method for manufacturing the tooling. The tooling may be used in electromagnetic welding of two contacted surfaces of molded parts by moving a joining inductor along the contacted surfaces, generating an electromagnetic field in an induction-sensitive component of the molded parts to heat a thermally activated coupling means of the molded parts to above a melting temperature of the coupling means.

A composite material is formed by irradiating a bonding position on a surface of the composite material with a laser to cause a reinforcing base member of the composite material, that is impregnated with a resin and onto which a bonding agent is applied, to be exposed and fluffed.

A laminate film manufacturing method is capable of preventing thickness unevenness of a cured layer and preventing wrinkling of the entire laminate film. A laminate film is manufactured by applying a coating solution including an active radiation curable resin to a surface of a first film that is continuously transported in an application part to form a coated film in a lamination part, laminating a second film that is continuously transported on the coated film to sandwich the coated film between the first film and the second film, and in a state in which the coated film is sandwiched between the first film and the second film, winding the first film around a backup roller and irradiating the coated film with infrared rays from an ultraviolet irradiation device while continuously transporting the first film to cure the coated film in a curing part so as to form a cured layer.

A repair method for a civil engineering work. The method includes the depositing, directly onto a portion of the work to be repaired, of a reinforcing structure formed from one or more successive layers of at least one reinforcing material which are each extruded in contact with the surface onto which the material is to be deposited, using a robot system, with the material being extruded in strips.

Provided is a method for forming a co-cured composite article. The method includes: providing a bag carrier; providing a vacuum bag, wherein the vacuum bag at least partially surrounds the bag carrier; providing an outer skin, wherein the outer skin at least partially surrounds the vacuum bag; forming a space between the bag carrier and the outer skin; and providing a filler between the outer skin and the bag carrier.

The present invention relates to a method for connecting two joining elements, these elements being connected by means of a thermally activatable adhesive with a flat heating element arranged therein, by suitable heating of the adhesive. The invention also relates to an assembly produced in this way from two joining elements and to an arrangement designed for carrying out a corresponding method.
