A method for producing a fencing material including the steps of: providing a border material having an interior surface; providing a mesh material having a front and a back; treating the interior surface of the border material to produce a tacky border material surface; placing a portion of the front and/or the back of the mesh material against the tacky border material surface; pressing the tacky border material surface and the mesh material together; and thermally bonding at least some portion of the front and the back of the mesh material with the interior surface of the border material. The border material being a polyvinyl chloride, the mesh being a polyvinyl chloride material and/or a vinyl coated material.

A process for welding of at least two separate vehicle panels (12, 14) to form an integral part (16) for a vehicle. There is provided at least one first panel (12) including a first weld line area (18) and at least one second panel (14) including a corresponding second weld line area (19), the second weld line area (19) abutting in a weldable relationship to the first weld line area (18). The first and second weld line areas (18, 19) have at least one first weldable portion (22) and at least one second portion (24) at which welding is substantially hindered during welding attachment of the first and second panels (12, 14). The process includes applying a curable adhesive at each second portion (24), placing in a welding fixture and welding the panels (12, 14) at each first weldable portion (22) such that the panels (12, 14) are held together during curing of the adhesive.

A method for surface preparation of a composite substrate prior to adhesive bonding. The surface preparation method includes applying a resin-containing peel ply onto a composite substrate, followed by co-curing. The resin-containing peel ply contains a non-removable textile carrier and a removable woven fabric embedded therein. After co-curing, the peel ply is removed from the composite substrate such that the removable woven fabric is removed but the non-removable textile carrier and a film of residual resin remain on the composite substrate, thereby creating a modified, bondable surface on the composite substrate. The composite substrate with the modified surface can be bonded to another composite substrate, whereby the textile carrier remains an integrated part of the final bonded structure.

A multi-material assembly is provided, as well as methods of making a multi-material assembly. The multi-material assembly includes a first coated structural component and a second structural component. The first coated structural component includes a first uncoated portion, and an adhesive is positioned between the second structural component and the first uncoated portion that secures the first coated structural component to the second structural component.

A minimally invasive method for attaching to a surface is provided. The method utilizes an attachment apparatus for non-penetrating mechanical attachment of components to a target surface. The apparatus includes a cartridge assembly and mounting assembly. Actuation of the cartridge assembly causes first and second exothermic reactants located between outer casing and the inner casing to come into contact and cause an exothermic reaction. This reaction liquefies a bonding material between the cartridge assembly and mounting assembly, allowing it to flow around the mounting assembly and onto a target surface creating a seal. Vacuum pressure will bind the mounting assembly to a target surface.

In an example, a method of sealing a bond cavity is described. The method comprises placing an adhesive around a perimeter of a first structure to be joined to a second structure. The method also comprises positioning the first structure relative to the second structure such that the adhesive is disposed between the first structure and the second structure. The method also comprises merging the first structure and the second structure until the first structure and the second structure are separated by a desired gap for bonding. The method also comprises heating the perimeter to at least partially cure the adhesive to form a leak-proof bond cavity perimeter between the first structure and the second structure.

In an example, a method is described. The method comprises forming a single hole into a bond gap repair area. The method also comprises evacuating, via an adhesive injection apparatus attached to the single hole, the bond gap repair area and an injection channel of the adhesive injection apparatus. The method also comprises forcing adhesive through the evacuated injection channel and into the evacuated bond gap repair area.

In an example, a method is described. The method comprises placing a repair patch over a repair area of a structure, the repair patch comprising a repair-patch hole. The method also comprises sealing the repair patch and repair area with a vacuum bag having a seal ring around a periphery of the vacuum bag. The method also comprises evacuating, via an adhesive injection apparatus attached to the repair-patch hole and the seal ring of the vacuum bag, the repair area and an injection channel of the adhesive injection apparatus. The method also comprises forcing adhesive through the evacuated injection channel and into the evacuated repair area.

Disclosed is a wind turbine blade and a method for its manufacture. The wind turbine blade comprises an upwind side shell part, a downwind side shell part, a leading edge and a trailing edge. A flatback web is arranged at the trailing edge, which couples the upwind side shell part with the downwind side shell part, wherein the flatback web comprises at least one U-shaped end section with a recess, into which the upwind side shell part and/or the downwind side shell part is inserted and bonded to the U-shaped end section by an adhesive.

A structural member (10) comprising: (i) a first carrier (12A) and a second carrier (12B), each carrier including a plurality of interconnecting ribs (16), each carrier further including one or more projections (28) extending from exterior walls (30) of each carrier; (ii) one or more secondary members (14) secured to one or more surfaces of each carrier; and (iii) an adhesive material (32) disposed on the first carrier (12A), the second carrier (12B), or both, wherein the first carrier (12A) and the second carrier (12B) are bonded to each other via the adhesive material (32).
