The present invention contemplates a method for forming a composite structure including a plurality of rigid layers and one or more reformable epoxy resin layers. The resulting composite is molded to form a non-planar composite structure.

The present invention provides low polyphenols (such as bisphenol A) tougheners for epoxy adhesives. The tougheners, and adhesives comprising the tougheners exhibit enhanced viscosity stability, e.g., compared to tougheners prepared from higher amounts of bisphenol A (and epoxy adhesives comprising them).

Structural panels and methods of making composite material for such structural panels may include applying a resin to a nonwoven fibrous web, where the nonwoven fibrous web includes a combination of glass fibers and polymer fibers. The web may be dried at a first stage temperature at or below a curing temperature of the resin for a time sufficient to substantially dry but not substantially cure the resin. The web may be laminated at a second stage temperature sufficient to fully cure the resin to produce a composite material. The second stage temperature may be above the melting point of the polymer fibers, and the resin may cause the composite material to retain a substantially rigid shape upon completion of the laminating operation.

A removable adhesive member and a display device using the same is provided. The removable adhesive member includes a first adhesive section, a first connecting section, and a tearing portion. The two opposite surfaces of the first adhesive section respectively adhere to the two objects. The first connecting section is connected to the first adhesive section. The first connecting section includes a first adhesive layer and two first protective layers. One side of the first adhesive section extends to form the first adhesive layer. The first protective layers are respectively laminated to two opposite surfaces of the first adhesive layer. The tearing portion is connected to the first adhesive section through the first connecting section, thereby avoiding rupture in pulling the tearing portion. The tearing portion is conveniently pulled up by a user, such that the first adhesive section removes from the objects to disassemble the objects.

The invention provides a thin film with integrated grating and polarizer. The thin film with integrated grating and polarizer includes a grating film and a polarizer film. The polarizer film is prepared on a light incident side of the grating film and thereby the grating film and the polarizer film are disposed integrally. By the above method, the invention can reduce film thickness and simplify manufacturing process.

A wafer laminate has an adhesive layer (2) sandwiched between a support (1) and a wafer (3), with a circuit-forming surface of the wafer facing the adhesive layer. The adhesive layer (2) includes a light-shielding resin layer (2a), an epoxy-containing siloxane skeleton resin layer (2b), and a non-silicone thermoplastic resin layer (2c).

Micromorphologically crack-free vitreous carbon articles having a length and width each of which is at least 10 mm, and a thickness of at least 5 mm are described, as well as multilayer laminates of micromorphologically crack-free vitreous carbon, and corresponding methods and apparatus for manufacture of same. 3D printed vitreous carbon articles are also described, together with 3D printing apparatus and methods for producing same. Methods are also described for forming vitreous carbon containing vitreous carbon nanolattice articles therein as filler. The vitreous carbon compositions, articles, and laminates of the disclosure overcome the thickness limitations of conventional vitreous carbon manufacturing methods and the microcracking issues attendant previous efforts to produce vitreous carbon of substantial size and thickness.

Disclosed is an automatic bonding system for an LCD device. The automatic bonding system includes a bonding unit configured to perform a process of bonding a first substrate to a second substrate, a first substrate supply unit configured to include an inverting arm and supply the first substrate to the bonding unit, a second substrate supply unit configured to include an adhesive resin coating unit and supply the second substrate to the bonding unit, a pre-hardening unit configured to perform a process of pre-hardening an adhesive resin that adheres the first and second substrates, and a hardening unit configured to perform a process of hardening the adhesive resin that adheres the first and second substrates. A gap between the first and second substrates bonded to each other by the bonding unit is a bonding gap controlled by a gap variable control stage.

A protective article is disclosed including a sheet with a first surface, and at least one adhesive portion arranged on the first surface. The adhesive is a water-based adhesive, such as a water-based acrylic adhesive, that allows the sheet to be non-permanently adhered to an object. The adhesive may be sprayed, rolled, printed, or stamped onto the first surface.

A building panel having a substrate and a layer arrangement, arranged on one side of the substrate. The layer arrangement having a surface layer and where the surface layer includes carpet fibres. At least the substrate at least partly includes a mechanical locking device for connecting at least two building panels. Where the substrate and the layer arrangement each includes a polymer of the same type of polymer.
