Corner joints and methods of forming corner joints are described herein. The corner joints may provide the appearance of a mortise and tenon joint on both the exterior and interior surfaces of the corner joint, but include a mitered connection within the joint. Structures including at least one of the corner joints are also described.

Exemplary embodiments are disclosed of liners, linings, and liquid containment vessels including the same. Also disclosed are exemplary method of providing liners and linings for liquid containment vessels, such as process tanks, immersion tanks, containment pits, gravity feed conduits for transferring or conveying liquid, etc. In an exemplary embodiment, a liner or lining is anchored to at least one structural component by at least one extrusion weld and at least one mechanical fastener. The mechanical fastener is coupled to the structural component. The extrusion weld is coupled to the mechanical fastener. The liner or lining may be anchored to a wide range of structural components, such as a frame, a framework, a frame member, a tank, a wall, a support member, a reinforcing member, an outer shell, a substrate (e.g., concrete, etc.) or sidewalls defining a pit or a gravity feed conduit, combinations thereof, other structures or components, etc.

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.

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.

Components are fastened with inserts that are placed into a hole in the component and bonded with an adhesive. A decoupling element is provided on the front face of the insert. This diverts the forces around the highly stressed front face of the inserts. The insert may be of a material with a lower stiffness compared with the adhesive. This arrangement may reduce stress peaks and increase the load capacity of the connection. A tool may be provided that reduces air inclusion between the insert and the component during fitting. The connection arrangement can be used when components of different stiffnesses have to be securely connected to one another. This applies to, among other things, fastening of fibre composite components or mineral components to metal components.
