10439235 · 2019-10-08 · ·

A method for joining incompatible materials is provided that includes the steps of welding a first component formed of a thermoplastic material and a second component of a porous material to one another to form a subassembly and optionally molding a third component around the subassembly. The method enables the incompatible first component and the third component to be joined to one another, such as to form an electrolyte battery flow frame around an ion exchange material and/or microporous separator material in order to form a separator for an electrolyte flow battery.

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.

Cell culture device and method of manufacturing the same

A cell culture device comprises a cell culture membrane and a substrate fixed to the cell culture membrane. The cell culture membrane is made from a thermosetting resin and has a plurality of pores that are open to at least one surface including a surface on a side that is in contact with the substrate. The substrate is made from a thermoplastic resin. In a contact region between the cell culture membrane and the substrate, part of the substrate is extended to form bulges in the pores of the cell culture membrane that are open in the contact region. This configuration suppresses reduction of the strength of the cell culture membrane and reduction of the flatness of the cell culture membrane (membrane accuracy) in the cell culture device in which the cell culture membrane and the substrate are fixed to each other.

Bonding of heat-activated films including a plasticizer

Articles including a polymer film, a plasticizer and a substrate are included. A method of bonding the film to the substrate includes the use of the plasticizer which provides a durable bond by using a lower temperatures and shorter bonding times than would be required in the absence of the plasticizer.

LIQUID-IMPERMEABLE STITCHING METHOD FOR SEAM OF VAPOR-PERMEABLE VIRUS-BARRIER FABRIC
20190168465 · 2019-06-06 ·

A fluid impervious stitching method for a seam of a vapor-permeable virus-barrier laminate. The laminate comprises: at least one thermoplastic resin fiber layer; at least one vapor-permeable virus-barrier thermoplastic elastomer film layer; and a bonding layer located between the two layers and formed of an adhesive capable of being fused with the two layers. In the stitching method, overlapping or stacking is performed to form a seam, and heat sealing is performed on the laminate at the seam. The temperature of heat sealing is higher than the melting point of a material layer having the highest melting point in the laminate, but lower than the temperature at which perforation or decomposition occurs in any material layer in the laminate. The heat-stitched seam has excellent windproof, vapor-permeable, virus barrier and liquid-barrier performance, has a smooth appearance without wrinkles, and feels soft. Also provided is a protective textile product prepared by means of the stitching method.
