A method of forming a transfer film is described. The transfer film includes a template layer having a first major surface and an opposing second major surface. The second major surface includes a structured non-planar release surface. A backfill layer is disposed upon and conforms to the non-planar structured surface. The backfill layer includes a first cross-linked polymer and a plurality of multifunctional monomers, which cure via different and independent curing mechanisms.

A method of manufacturing a building panel including a core, a decorative layer and a balancing layer, including mechanically processing production waste including a resin impregnated paper to processed production waste, applying a first mix including said processed production waste and a thermosetting binder on a first surface of a core, applying a decorative layer on a second surface of the core, and curing the first mix to a balancing layer of the building panel. Also, a building panel formed by such a method.

A joined article including: a resin (1) having a linear expansion coefficient at 30? C. to 200? C. of 17 ppm/? C. or higher and a thickness of 5 to 100 ?m; and a metal joined to a surface of the resin (1) and having a thickness of 5 to 50 ?m. The resin (1) includes a heat-affected layer that is close to the metal and that occupies 80% or less of the thickness of the resin (1), and the joined article is a dielectric material for a substrate. Also disclosed is a substrate including the joined article and a resin (2) stacked on the joined article.

One aspect of the present invention provides a composite sheet which comprises a nitride sintered body having a porous structure and a semi-cured product of a thermosetting resin composition impregnated into the nitride sintered body, the line roughness Rz specified by JIS B 0601:2013 of at least one main surface being 10 m or less.

A composite wood panel with an overlay made using a butylated (including, but not limited to, iso-butylated or n-butylated) melamine formaldehyde (BMF) resin cross-linking agent, substituting for or replacing some or all of the methylated melamine formaldehyde resin cross-linking agent. This results in a BMF-containing MF resin component that is more elastic and flexible, and provides those properties to paper overlays made with a BMF resin mixture (BMF overlays). BMF overlays applied to the surfaces of engineered wood panels or boards results in the reduction or elimination of the fissures produced during the pressing and production processes.

The invention relates to a method for manufacture of a product or in completion of a product. A flexible mat (20) is manufactured from an incompletely cured thermo-setting plastic, wherein the mat comprises an article (10) of electrically conductive material. The incompletely cured mat (20) including the article (10) is then formed as a function of a forming tool or to lie against or for contact with a product, whereafter final curing of the mat (20) is executed by supplying electric power to the article (10) or by external heat application or ultraviolet light. The invention also relates to an arrangement and uses.

The transfer film for in-mold molding of the invention has transfer layer 11 being a transfer layer to be transferred onto a transfer object in in-mold molding and cured by irradiation with an active energy ray after being transferred; and film-like base L0. Transfer layer 11 has topcoat layer L2 laminated on base L0 to be arranged on a surface of a molded product after in-mold molding; and conductor layer L4 laminated on a side opposite to a base L0 side of topcoat layer L2, and laminated on topcoat layer L2. Topcoat layer L2 is composed of a mixed composition containing an active energy ray-curable resin and a thermosetting resin, and conductor layer L4 is formed of at least one kind selected from the group of a flexible metal, carbon and conductive polymer.

Provided are stiffened stringer panels with integrated indexing stacks. An example composite panel comprises a skin member having an inner surface. An index for positioning a support tool comprises a first set and second set of layered laminate stacks coupled to the inner surface such that a channel is formed between the first and second set of layered laminate stacks. The first and second set of layered laminate stacks is configured to cradle a support tool in the channel to automatically align the support tool relative to the panel. A stringer may include a cap portion that extends from the first set to the second set of layered laminate stacks to form flange portions on the inner surface of the skin member. The index and the skin member may be co-cured or co-bonded.

An instrument panel structure includes: a base material that has both end portions in the longitudinal direction bent toward the lower face side to form a side face portion; a foamed material that covers a surface of the base material; and a skin that covers a surface of the foamed material. The instrument panel structure also includes a sealing rib that protrudes outward in the longitudinal direction from the side face portion in an arrangement position spaced apart by a predetermined gap toward the lower face side from a bent position of the base material, and to which an end portion of the skin is joined. The instrument panel structure also includes a widening rib that protrudes outward in the longitudinal direction from the side face portion on an upper face side of the arrangement position of the sealing rib on the side face portion, and is covered with the foamed material.

A composite panel is constructed by preparing a panel assembly layup including a first prepreg layer having reinforcement material, a first layer of a resin formulation upon a first outer surface, and a second layer of the resin formulation upon an opposing outer surface, where the first layer is thinner than the second layer, and the first layer is presented toward a mold. The layup includes a core layer directly abutting the second layer. They layup includes a second prepreg layer having a first layer of the resin formulation upon a first outer surface, and a second layer of the resin formulation upon an opposing outer surface, where the first layer is thinner than the second layer, and the second layer directly abuts the core layer. The panel assembly is cured in the mold.
