An example method of joining a first structure and a second structure is described that includes forming a bond cavity between a first structure and a second structure, placing a semi-permeable breather material at one or more exits of the bond cavity, placing a vacuum bag around the bond cavity and the semi-permeable breather material, evacuating the bond cavity via a vacuum port and forcing adhesive into the bond cavity via an adhesive port while the bond cavity is evacuated, and curing the adhesive via one or more heaters to bond the first structure to the second structure.

An additively manufactured node is disclosed. A node is an additively manufactured (AM) structure that includes a feature, e.g., a socket, a channel, etc., for accepting another structure, e.g., a tube, a panel, etc. The node can include a node surface of a receptacle extending into the node. The receptacle can receive a structure, and a seal interface on the node surface can seat a seal member between the node surface and the structure to create an adhesive region between the node and the structure, the adhesive region being bounded by the node surface, the structure, and the seal member. The node can also include two channels connecting an exterior surface of the node to the adhesive region. In this way, adhesive can be injected into the adhesive region between the node and the structure, and the adhesive can be contained by the seal member.

An example method of joining a first structure and a second structure is described that includes placing an adhesive within a bond cavity for bonding a first structure to a second structure, securing a vacuum bag to the first structure and the second structure so as to surround a portion of the first structure and the second structure, evacuating the bond cavity via a vacuum port to deaerate the adhesive within the bond cavity, after deaerating the adhesive, moving the first structure and the second structure relative to one another such that deaerated adhesive is disposed between the first structure and the second structure, and curing, via one or more heaters, the deaerated adhesive disposed between the first structure and the second structure to bond the first structure to the second structure.

A method for forming a seal between structural components includes placing a retainer flap on a first side of a first structural component over a first channel within the first structural component and over a second channel within the first structural component such that the retainer flap, the first side of the first structural component, and a second structural component form a cavity. The first channel extends between the first side of the first structural component and a second side of the first structural component that is opposite the first side. The second channel extends between the first side of the first structural component and the second side of the first structural component. The method also includes evacuating the cavity through the first channel, thereby forcing the retainer flap against the second structural component and forcing a sealant to flow through the second channel into the cavity.

A generator injection tool is provided. The generator injection tool injects an adhesive into a generator that includes a rotor positioned within a stator having a stator vent, the stator and rotor having a gap therebetween. The generator injection tool includes a first carriage sized to fit within the gap, a tube, a first motor, a controller, and an adhesive source. An end of the tube is movable between a first position in which the end is outside of the stator vent and a second position within the stator vent. The first motor is operable to move the tube between the first position and the second position. The controller is operable to selectively activate the first motor to position the end of the tube within the stator vent. The adhesive source moves the adhesive through the tube end to inject a portion of the adhesive into the stator vent.

A method of bonding a composite vane to at least one support. The method includes positioning an end of a vane within a support, causing an adhesive to flow between the vane and the support from an inlet to an outlet, and reversing the flow of adhesive from the outlet towards the inlet.

The present invention relates to a method for manufacturing webs (1) that are intended to be involved in the makeup of a reinforcing ply (2) for a pneumatic tyre (20), said method comprising a preparation step (a), during which a plurality of straight-thread strips (7, 107, 207), which are each formed of a plurality of continuous reinforcing threads (4) that are embedded in a layer of rubber (5), are prepared, a butt-joining step (b), during which said straight-thread strips (7, 107, 207) are butt-joined in pairs to form a straight-thread ply (3), then a cutting step (c), during which the straight-thread ply (3) is inserted into a cutter (8) and the straight-thread ply (3) is severed transversely so as to form webs, wherein, in said method, the frontal width (W3) of the straight-thread ply (3) that is produced during the butt-joining step (b) and then inserted into the cutter (8) is equal to or greater than 50%, equal to or greater than 75%, equal to or greater than 80%, or even equal to or greater than 90%, of the cutter inlet width (W8), whereas the widest frontal width (W7, W107, W207) of the straight-thread strips is less than or equal to 50%, less than or equal to 40%, less than or equal to 25%, less than or equal to 10%, or even less than or equal to 5%, of said cutter inlet width (W8).
