A method of making a modular wind turbine blade is described. The modular blade comprises first and second blade modules connected together by a scarf joint between tapered spar caps of the respective blade modules. According to the method, first and second blade modules are laid up in the same mould assembly. A separating layer is arranged between the layups of the first and second module in a joint region of the mould. The separating layer has a thickness corresponding to a required bond thickness in the scarf joint when the modules are bonded together.

In a state in which an insert (310) is embedded in an embedding opening of a panel (300) and a nozzle (211) of a dispenser (210) is located above an injection hole of the insert, an air cylinder (230) presses an edge of a discharge port (212) of the nozzle on an edge of the injection hole of the insert. Subsequently, the dispenser discharges an adhesive from the discharge port of the nozzle. The adhesive is injected from the injection hole of the insert, and fills a gap between the insert and the panel. Therefore, the insert is fixed to the panel.

A device for reinforcing, sealing or insulating a structural element in a motor vehicle includes a support having a clip for pre-fixing the device in the structural element. The clip includes a base and two flexible wings arranged on the base. The device furthermore includes an adhesive for adhesively bonding the support in the structural element. The device furthermore includes an insertion element, which can be inserted in such a way into an interspace between the base and the wings of the clip when the device is pre-fixed on the structural element by the clip that the flexible wings are restricted in their freedom of movement.

A method of attaching a tip extension to a wind turbine blade is described. The method comprises: fitting the tip extension over a tip end of the blade such that an overlap region is defined between an outer surface of the blade and an inner surface of the tip extension; and supplying adhesive to the overlap region via one or more holes provided in the tip extension to bond the tip extension to the blade. In preferred embodiments, adhesive dams are provided in the overlap region to define bond cavities and constrain the adhesive within the bond cavities. An assembly comprising a wind turbine blade and a tip extension bonded thereto is also described.

A tunnel segment gasket and a method for making and using a tunnel segment gasket (1, 1) comprising a shaped profile (3, 3) having at least two anchoring legs (5, 5) for casting in to a tunnel segment (6, 6); a plurality of longitudinally extending bores (7, 7); a shot film joint (43) and a strengthening element (11, 4) at the base (9) of the gasket (1, 1).

A method for assembling two parts, referred to as first and second parts, the first part being produced from composite material with fibrous reinforcement embedded in a thermosetting or thermoplastic matrix, the method comprising the steps of: obtaining the first part comprising, on all or part of an outer surface, a first amorphous thermoplastic film; positioning the first part and the second part such that the first amorphous thermoplastic film is placed opposite the second part; introducing a thermosetting resin between the first amorphous thermoplastic film and the second part; at least partially polymerising the thermosetting resin. When the two parts comprise an amorphous thermoplastic film, the parts are positioned such that the respective amorphous thermoplastic films are placed opposite each other, and the thermosetting resin is introduced between the amorphous thermoplastic films.

Method for the production of a pacifier teat and pacifier teat with a suction section forming a cavity, to which suction section a shaft adjoins, wherein an elastic hollow body having suction section and the shaft is pre-formed in an injection or in a dipping process and opposite wall sections of the pre-formed hollow body are connected with each other in the region of the shaft.

The invention relates to a method for connecting two fibre-reinforced plastic components, comprising the following steps: producing a first fibre-reinforced plastic component, wherein a fabric made of fibrous matting is provided, which is impregnated with a resin-curing agent mixture, which is then subsequently cured, wherein the part of the surface of the first fibre-reinforced plastic component, which is to be later adhered to the second fibre-reinforced plastic component (hereinafter also referred to as joining surface), is masked with an adhesive strip before the impregnation of the fibrous matting with the resin-curing agent mixture; producing a second fibre-reinforced plastic component using the above steps, wherein the part of the surface of the second fibre-reinforced plastic component, which is to be later adhered to the first fibre-reinforced plastic component, is also masked with an adhesive strip before the impregnation of the fibrous matting with the resin-curing agent mixture; removing the adhesive strips from the two finished fibre-reinforced plastic components; bringing the two joining surfaces in contact; introducing a resin-curing agent mixture between the two joining surfaces; curing the resin-curing agent mixture, wherein the adhesive strip has a carrier film, on one side of which an adhesive mass, in particular self-adhesive mass is applied, and wherein the carrier film consists of fluoropolymers, polyethylene polymers, undrawn polypropylenes or of metal, and the adhesive mass is an acrylate or silicon adhesive mass.

A method of manufacturing a medical device, including forming a flexible base portion to have a plurality of through-holes therethrough, placing the flexible base portion on a non-patient side of an adhesive patch with the through-holes in communication with the adhesive patch, dispensing an adhesive into the through-holes onto the adhesive patch and walls of the flexible base portion surrounding the through-holes; and curing the adhesive to form an adhesive plug mechanically bonding the flexible base portion to the adhesive patch.

A method of repairing a composite structure includes providing an assembled composite structure comprising a substantially rigid outer component, wherein the composite structure comprises a void space at least partially bounded by the outer component. The method further includes forming an injection hole through the outer component to provide a path between the void space and space external to the composite structure. The method further includes injecting foam into the void space through the injection hole while the foam is in a substantially unexpanded state and expanding the foam within the void space.
