A method for forming a hybrid heat exchanger is provided. The method includes laser-texturing a metal surface to create a plurality of microstructures and subsequently melt-bonding a plastic component to the plurality of microstructures. During melt-bonding, plastic material penetrates the plurality of microstructures and conforms to the plastic component to the metal surface. After hardening inside the microstructures, the plastic component adheres to the metal surface as a hybrid component. As a result, a fastener or snap connection is not required, and the plastic-metal joint provides a barrier to water, glycol-based fluids, air, and other fluids.

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.

Provided is a production method for a film laminate by which a tough film can be bonded to a brittle film while the breakage of the brittle film is prevented. The production method for a film laminate of the present invention includes bonding a tough film having an elongated shape to a brittle film having an elongated shape while conveying the brittle film, wherein the method includes bonding the tough film and the brittle film to each other by bringing the tough film close to the brittle film, followed by blowing of a gas from a side of the tough film opposite to the brittle film.

A tool presses a joining element against a first object into a first opening of the first object while mechanical vibration energy is coupled into the first object and the joining element. Vibration energy and pressing force make the thermoplastic material of the distal portion of the joining element flowable and interpenetrates structures of the first object to yield, after re-solidification, an anchoring of the distal portion of the joining element in the first object. The second object is placed so that a proximal portion of the joining element is inserted into a second opening, and the first and second objects are pressed against each other while mechanical vibration energy is coupled into one of the first and second objects, until thermoplastic material of the joining element proximal portion is made flowable and interpenetrates structures of the second object to yield, after re-solidification, an anchoring in the second object.

Methods of producing polymer-metal hybrid components that are bonded by C—O-M bonds at the interface using at least one of the hot pressing, rolling, and injection molding methods to create chemical bond formation conditions at the polymer and metal interface. When the thermal cycle and compressive pressure specified herein is combinationally created at the polymer and metal interfaced, strong C—O-M bonds forms at the interface and strongly bonds the metal and polymer together through the reaction carbonyl groups (C═O) in polymer and the metal surface. For polymers lacking enough carbonyl groups, new functional groups can be in-situ generation through introducing distributed air pockets at the polymer-metal interface for forming 3-dimensional distributed C—O-M bonds at the interface.

The present disclosure relates to articles and methods of sealing light redirecting film constructions comprising a microstructured optical film, such as a daylight redirecting film, bonded to another film. This type of assembly may serve various purposes. For example, the assembly may protect the structured film, provide additional functionality, such as diffusion or infrared reflection, and/or facilitate attachment of the microstructured optical film to a mounting surface, such as a glazing or window pane. The methods for sealing the edge of a light redirecting construction inhibit ingress of water and other contaminants during the film installation and afterwards during its regular use.

A vacuum adiabatic body, a method for fabricating a vacuum adiabatic body, a porous substance package, and a refrigerator including a vacuum adiabatic body and a porous substance package are provided. The vacuum adiabatic body may include a first plate, a second plate, a seal, a support, a heat resistance device, and an exhaust port. The support may include a porous substance and a film made of a resin material, the film configured to accommodate the porous substance therein. Accordingly, it may be possible to provide a vacuum adiabatic body through an inexpensive process.

A method for joining a thermoplastic film to a metal component, at least comprising the following method steps: providing the metal component with a joining surface, incorporating microstructures and/or nanostructures into the joining surface of the metal component, arranging the thermoplastic film on the joining surface of the metal component, softening the thermoplastic film by heating to a temperature above the glass transition temperature of the thermoplastic film, pressing the softened thermoplastic film onto the joining surface of the metal component in such a way that part of the softened thermoplastic film penetrates into the microstructures and/or nanostructures in the joining surface of the metal component, and obtaining an interlocking connection between the thermoplastic film and the metal component after the thermoplastic film has cooled.
