REDUCING RESIN SQUEEZE-OUT
Described herein are techniques for reducing resin squeeze-out including a method comprising receiving a first component and a second component, where the first component is configured to be joined to the second component at an overlap area using an adhesive layer to form a structure having a ledge. The method further comprises applying the adhesive layer to the overlap area on the first component. The method further comprises selectively curing a portion of the adhesive layer adjacent to the ledge. The method further comprises forming the structure by combining the first component, the second component, and the adhesive layer and curing a remainder of the adhesive layer.
Wind turbine blade including protective cover
A wind turbine blade includes a protective cover attached along the blade by a layer of adhesive. The adhesive is a general purpose adhesive, and the adhesive forms a joint or sealing between an outer edge of the cover section of the blade and the surface of the blade so that the outer edge is covered by the adhesive and so that the joint forms an oblique surface from the outer edge to the surface of the blade. The joint has a first height at the outer edge and a second height at the position where it ends at the surface of the blade. The second height is smaller than the first height and smaller than 0.2 millimetres, and the joint is integrally formed with the layer of adhesive.
Glued arrangement
A glued arrangement, preferably for a motor vehicle, is disclosed. The glued arrangement includes a first component, a second component, and at least one adhesive layer for connecting the two components. The adhesive layer includes a central zone and an edge zone that surrounds the central zone where, in the hardened state, the adhesive in the edge zone has a higher elasticity than the adhesive in the central zone.
ADHESIVE AND ITS PREPARATION AND APPLICATION
The present invention relates to an adhesive, a preparation method and application thereof, particularly the application for bonding glass fiber composites, and a bonded article obtained by using the adhesive. The adhesive comprises: a polyisocyanate having an isocyanate functionality of not less than 2; an epoxy-modified polyether polyol; a hydroxyl-containing acrylate; a redox catalyst; a silane coupling agent; optionally a polyol containing bisphenol A structure; and optionally a polymer polyol different from the epoxy-modified polyether polyol. The adhesive according to the present invention has the advantages of being insensitive to moisture, good bonding properties and a long pot life.
METAL/FIBER-REINFORCED RESIN MATERIAL COMPOSITE
[Problem]
To provide a metal/fiber-reinforced resin material composite in which a metal member and a fiber-reinforced resin material are firmly bonded, a light weight and excellent workability are obtained while the strength is enhanced, and the amount of the fiber-reinforced resin material used can be reduced.
[Solution]
A metal/fiber-reinforced resin material composite comprising a metal member, and a first fiber-reinforced resin material having a matrix resin and a reinforcement fiber material, the metal member and the first fiber-reinforced resin material being formed into a composite with an adhesive resin layer interposed therebetween, wherein the adhesive resin layer is obtained by solidifying or curing an adhesive resin composition containing at least 50 mass parts of a phenoxy resin (A), and the maximum load of the metal/fiber-reinforced resin material composite is greater than the total load of the maximum load of the metal member alone and the maximum load of the fiber-reinforced resin material alone (i.e., so as to display a super-law-of-mixture (or law of over-mixture) that surpasses the law of mixture with respect to the tensile load).
METHOD FOR MANUFACTURING AUTOMOTIVE GLASS WITH MEMBER, AND SUPERHEATED STEAM CHAMBER USED IN MANUFACTURING OF AUTOMOTIVE GLASS WITH MEMBER
Provided is a method for producing automotive glass with a member having a U-shaped cross section in a highly efficient and space-saving manner. The present invention relates to a method for producing automotive glass with a member by curing an adhesive for bonding an adherend 21 having a U-shaped cross section to an edge portion 20a of automotive glass 20, using a superheated steam generator 1. The superheated steam generator 1 includes a boiler part 2 for generating steam, a superheating unit 3 for superheating steam generated in the boiler part 2, and a superheated steam chamber 10 having a groove portion 111 for covering the edge portion 20a of the automotive glass 20 and including superheated steam ejection portions 12 for ejecting superheated steam supplied from the superheating unit 3. The step of curing the adhesive comprises covering the edge portion 20a of the automotive glass 20 together with the adherend 21, with the groove portion 111 of the superheated steam chamber 10, and spraying superheated steam to the adherend 21 from both sides of automotive glass 20 from the superheated steam ejection portions 12.
Rivet bonding workpiece stack-ups having one or more polymer composite workpieces
A method of rivet bonding a workpiece stack-up that includes one or more polymer composite workpieces, such as carbon fiber composite workpieces, involves several steps. In one step, adhesive is applied to a surface of the workpiece stack-up. In another step, workpiecesincluding the polymer composite workpiece(s)are brought together. In yet another step the adhesive is partially or more cured. A rivet is installed through the workpiece stack-up and through the adhesive in another step. The method strengthens the resulting rivet-bonded joint by minimizing or altogether precluding fracture, cracking, and/or delamination thereat.
Polyurethane bonding process for fuel bladders
A method of bonding a metal fitting to a polyurethane structure, the method comprising abrading a surface of the metal fitting with an abrasive; cleaning the metal fitting with a solvent; cleaning a surface of the polyurethane structure with an alcohol; applying a primer to the surface of the metal fitting; applying an adhesive to the surface of the metal fitting and the surface of the polyurethane structure; applying a liquid polyurethane compound to the surface of the metal fitting and the surface of the polyurethane structure; and pressing the surface of the metal fitting against the surface of the polyurethane structure to form an assembly. The primer can comprise a first resin and a first catalyst in a ratio of about 1.1 to 1; the adhesive can comprise a second resin and a second catalyst in a ratio of about 3 to 1; and the liquid polyurethane compound can comprise a third resin and a third catalyst in a ratio of about 10 to 1.
Material dispense tips and methods for forming the same
A dispense tip constructed and arranged to communicate with a material dispensing pump comprises an elongated neck and a molded base having a first portion and a second portion opposite the first portion. The neck extends from the first portion of the base. The second portion is constructed and arranged to abut an outlet surface of the pump. An outermost region of the second portion of the base includes a compressible fluid-tight surface that compliantly conforms to the outlet surface when the dispense tip is mounted to the pump.
Selectively activated frangible bonding system
An intentionally activated frangible bonding system comprises a frangible adhesive, adhesive primer, composite material matrix, and/or the like, having a polydispersion of at least one additive spread throughout the frangible bonding material. The additive degrades a bond provided by the frangible bonding material, upon application of a specific energy to the frangible bonding material. An energy emitter is configured to selectively direct the specific energy toward a structure or assembly comprising components bonded by the frangible bonding material to degrade the frangible bonding material bonding the components for disassembly.
