METHOD OF MANUFACTURING COMPOSITE MEMBER AND THE COMPOSITE MEMBER
A method of manufacturing a composite member including an aluminum member and a fiber-reinforced resin member bonded to each other, the method including: performing blasting on a surface of the aluminum member; modifying the surface of the aluminum member into aluminum hydroxide, the modifying including causing the surface of the aluminum member having undergone blasting to react with water by using at least one of heat and plasma; and directly bonding the fiber-reinforced resin member to the surface of the aluminum member modified to the aluminum hydroxide.
Thermoplastic/thermoset grafted composites
Disclosed are thermoset/thermoplastic composites that include a thermoset component directly or indirectly bonded to a thermoplastic component via a crosslinked binding layer between the two. The crosslinked binding layer is bonded to the thermoplastic component via epoxy linkages and is either directly or indirectly bonded to the thermoset component via epoxy linkages. The composite can be a laminate and can provide a route for addition of a thermoplastic implant to a thermoset structure.
Method for manufacturing PDMS device and PDMS device manufactured thereby
A method for manufacturing a PDMS device in accordance with an exemplary embodiment of the present invention surface treats the entire surface of a pattern with a thiol group (SH), so that a hydrogel may be connected to the surface of the pattern by a covalent bond under ultraviolet rays. Therefore, a PDMS device manufactured by the above method has an advantage in that the shape thereof may be stably maintained without the swelling or desorption of a hydrogel even when an electrolyte is filled in a pattern.
Process for making a porous filter element, porous filter elements made thereby, and filter devices including them
The present disclosure relates more to processes for making a filter element that includes a filter membrane having a strip of thermoplastic polymer material laminated thereto, for example, as a strip along an edge of the filter membrane. For example, one such process includes providing a sheet of filter membrane having a first surface and an opposed second surface; providing a strip of thermoplastic polymer material having a first surface and an opposed second surface; contacting the first surface of the strip of thermoplastic polymer material with the first surface of the filter membrane; and softening the strip of thermoplastic polymer material at at least its first surface by irradiation with laser radiation; such that the softened polymer material of the first surface of the strip of thermoplastic polymer material bonds to the first surface of the filter membrane upon hardening.
Copper or copper alloy article comprising surface-modified polyester-based resin and manufacturing method
Disclosed is a copper alloy article including: a substrate 10 made of a copper alloy; a polyester-based resin body 40; and a compound layer 20 for bonding the substrate 10 and the polyester-based resin body 40, wherein the compound layer 20 contains; a compound having a nitrogen-containing functional group and a silanol group, and an alkane type amine-based silane coupling agent.
Method for welding polyamide and poly(meth)acrylate plastics
The invention relates to a method for welding a polyamide plastic and a poly(meth)acrylateparticularly a polymethyl methacrylateplastic using a primer, said primer containing at least one copolymer synthesised from at least one styrene or styrene derivative and at least one maleic anhydride or maleic anhydride derivative. The invention also relates to correspondingly welded products.
HIGH-SPEED POLYMER-TO-METAL DIRECT JOINING SYSTEM AND METHOD
A method of directly joining a polymer to a metal along a joint interface through the formation of CO-M chemical bonds, where M represents an element in the metal to be joined. The method includes heating the metal to a predetermined temperature above a glass transition temperature of the polymer and less than a flash ignition temperature of the polymer and less than a metal melting temperature of the metal; physically contacting at least one of the metal and the polymer; and applying compression pressure to the joint interface of the metal and the polymer when the metal is above the glass transition temperature of the polymer and less than the flash ignition temperature of the polymer and less than the metal melting temperature of the metal to generate intimate atomic contact between the metal and the polymer to create CO-M chemical bonds between the metal and the polymer.
Method for producing plate packs
Plate packs are produced from a sheet-like starting product (1), which is cut to form plates, which are stacked to form a plate pack. The plates within the plate stack are joined to one another by a bonding agent. The bonding agent used is a cyanoacrylate adhesive with a high temperature stability rating. It is applied to a wetting layer (14) for the adhesive. The wetting layer (14) is formulated to a pH in a region >7. The cyanoacrylate adhesive with a high temperature stability rating is able to spread on the wetting layer (14) such that effective wetting takes place, thus achieving quick and secure joining of the plates to one another.
Method for producing a structural component
A method for manufacturing a structural assembly comprising at least two assembly components interconnected by means of a thermoplastic plastics material, and useful in the field of aviation or space travel. First, a first assembly component and a second assembly component are provided and arranged so as to form an arrangement. Second, the arrangement is subjected to creep forming at a temperature which is selected in such a way that the thermoplastic plastics material melts at least in part during the creep forming so as to connect the first assembly component and the second assembly component. The invention further relates to structural assemblies, in particular for an aircraft or spacecraft, and to an aircraft or spacecraft comprising a structural assembly of this type.
Method of repairing or reinforcing wind turbine blade, or attaching accessory part to wind turbine blade
A method of repairing or reinforcing, or attaching an accessory part to a wind turbine blade includes: determining a criterion to be satisfied by a repair member including a reinforcing fiber and a UV curable resin, the criterion being an adhesion strength of the repair member relative to a base member of the wind turbine blade; determining a work condition including: dimensions of the repair member, the number of the layers of the reinforcing fiber in the repair member, and/or a fiber extension direction of the reinforcing fiber, based on a damage condition of a repair target portion of the wind turbine blade; placing the reinforcing fiber and UV curable resin on the repair target portion based on the determined work condition; and obtaining the repair member by curing the UV curable resin so that the adhesion strength of the repair member relative to the base member satisfies the criterion.
