Two composite laminates are joined together by a bondline having portions exposed to the ambient environment. The bondline contains scrim having an electrical conductivity and impedance matched to that of the laminates in order to mitigate effects of lightning strikes.

A connection between at least two joining partners includes an interlying joining gap, with opposite joining surfaces. At least one of the joining surfaces is wetted with an adhesive layer having incorporated and/or attached solids particles, and the remaining joining gap is filled with an inorganic and/or organic filler material.

A method and apparatus for forming a joint. A composite insert may be placed into a joint region for a first structure. The composite insert may comprise a structure having a first portion, a second portion, and a third portion all extending from a junction; and a resin impregnated into the structure to form the composite insert. The second structure may be laid up. The composite insert may be bonded to the first structure and the second structure.

A composite wood floor board assembled adjacent to another composite wood floor board, each the board comprising: a top layer of laminated hardwood comprising: a top side; a bottom side; a first lateral side; and a second lateral side opposite the first lateral side, wherein at least one of the first and second lateral sides is formed without shiplap lips; and a bottom layer comprising a planar fiber-reinforced polymer composite that is bonded to the bottom side of the top layer of the laminated hardwood and reinforces the top layer, wherein the bottom layer of fiber-reinforced polymer composite extends laterally outwardly by a distance up to two inches (2) from the first lateral side of the top layer, and wherein a part of the bottom layer of the composite wood floor board is bonded to the top layer with a first adhesive and a part of the bottom layer is bonded with a second adhesive or sealant.

Sucker rods include end fittings having an outer wedge portion proximate to an open end, an inner wedge portion proximate to a closed end, and an intermediate wedge portion between the outer and inner wedges. Each wedge includes a leading edge, a trailing edge, and an angle between the leading and trailing edges. The triangular configuration, length of the leading edge, the length of the trailing edge, and size of the angle in each wedge portion cause distribution of force, such that compressive forces distributed to the rod proximate the closed end exceed compressive forces distributed to the rod proximate the open end.

A node to panel interface structure for use in a transport structure such as a vehicle is disclosed. In an aspect, the node includes a base, first and second sides protruding from the base to form a recess for receiving a panel, ports for adhesive injection and/or vacuum generation, one or more adhesive regions disposed on a surface of each side adjacent the panel, and at least one channel coupled between the first and second ports and configured to fill the adhesive regions with an adhesive, the adhesive being cured to form a node-panel interface. The node may be additively manufactured. In an exemplary embodiment, the node may use sealant features for including sealants that border and define the adhesive regions, and that may hermetically seal the region before and after adhesive injection. In another embodiment, the node may include isolation features for including isolators for inhibiting galvanic corrosion. In another aspect, adhesive may be filled serially on the adhesive regions on the first side and then on the adhesive regions on the second side. Adhesive may alternatively may be filled in parallel, or concurrently, on the adhesive regions of both sides.

A device for securing a primary coil used for inductive charging fastens a rail to an underlying surface. The rail has a lower wall and at least one side wall. The device includes a connection strip, which has a longitudinal extent along the rail and which has an adequate width for covering the lower wall and at least partially the at least one side wall of the rail. The connection strip has an outer connection layer on an outer face, which outer connection layer is designed to produce adhesion between the connection strip and the surface along the lower wall of the rail. The connection strip has at least one inner connection layer on an inner face, which inner connection layer is designed to produce adhesion between the at least one side wall of the rail and the connection strip along the at least one side wall of the rail. The device also includes a housing, which can be connected to the rail and which blocks access to the rail when the housing is connected to the rail.

A joint assembly that includes first and second joint members is provided. The joint assembly includes a reinforcing member that has an outer surface that defines a plurality of cavities. Foam is located in the joint members and engages the reinforcing member such that the foam is located in the cavities of the reinforcing member. Additionally or alternatively, the joint assembly may be constructed so that the inner surface of the first joint member defines a plurality of cavities. Foam is located in the joint members and engages the inner surface of the first joint member so that it is located in the cavities of the first joint member. Various methods of manufacturing and treating the joint assembly are also provided.

A method of retaining a molded-in insert in a fiber reinforced thermoplastic composite material and forming a high strength mechanical locking mechanism is provided. The method includes fixing a molded-in insert in a mold cavity. The insert has a cylindrical body and at least one circumferential groove formed in the cylindrical body, and has a substantially concave configuration, and the groove has a groove radius of 0.025 inch or greater, and greater than or equal to a groove depth. The method includes introducing a fiber reinforced thermoplastic composite material into the mold cavity and around the molded-in insert, enclosing the mold cavity, heating and compressing the material in the mold cavity to consolidate the material around the molded-in insert and to form a consolidated fiber reinforced thermoplastic composite structure with the molded-in insert, cooling the structure, and removing the structure with the molded-in insert from the mold cavity.
