A prepreg includes composition elements [A], [B], and [C] described below, [A] a reinforcing fiber, [B] a thermosetting resin, and [C] a thermoplastic resin. [C] is present on a surface of the prepreg, [B] contains a first curing agent [b1] and a second curing agent [b2], and the reinforcing fiber of [A] that crosses over a boundary surface between a resin region containing [B] and a resin region containing [C] and that is in contact with both resin regions is present.

A marine deck member and the process for forming the same are provided. The marine deck member comprises a sandwich-type composite panel made by a compression molding process. In such a process, the panel is made by subjecting a heated stack of layers of material to cold pressing in a mold. The cellular core has a 2-D array of cells, with end faces open to the respective layers or skins. The surface traction of this type of composite panel can be enhanced for marine deck applications by controlled debossing, or embossing, of the first skin while it cools in the compression mold. The debossing effect can be affected by applying pressurized gas, e.g., pressurized air, onto the outer surface of the first skin while in the compression mold. The embossing can be affected by applying vacuum pressure on the outer surface of the first skin while in the compression mold.

A decorative panel includes a substrate, a decor layer and a cover layer. The cover layer has a lacquer or is composed of a lacquer. The lacquer includes antimicrobial additives; and has an acrylate matrix and/or a methacrylate matrix.

Provided herein are composite materials comprising a layup consisting of one or more surfacing sheets comingled with a carbon fiber non-woven mat. The surfacing sheet may comprise polyamide-6 and the carbon fiber non-woven mat may comprise carbon fibers that have been recycled. The surfacing sheets comprise sub-micron scale particles for reducing the thermal expansion coefficient of the surfacing sheets. The resulting layup is suitable for use in the formation of articles, particularly articles requiring a smooth finish absent of defects caused by underlying surfaces having irregular compositions or textures.

A method to produce a panel unit, including providing a core having a first surface and a second surface opposite the first surface, applying a surface layer to the first surface of the core, the surface layer including a wood veneer layer and a first binder layer for adhering the wood veneer layer to the first surface of the core, applying a balancing layer to a second surface of the core, the balancing layer including an unimpregnated paper and a second binder layer for adhering the unimpregnated paper to the second surface of the core, applying pressure to the surface layer, the balancing layer, and the core to form a panel unit. The disclosure also relates to a panel.

A multi-layered thermoplastic roofing membrane comprising a planar body including at least three layers, said at least three layers including (i) a top layer that includes magnesium hydroxide dispersed within a thermoplastic resin, (ii) an upper middle layer disposed below said top layer and including magnesium hydroxide and calcium carbonate dispersed within a thermoplastic resin, and (iii) a lower layer disposed below said upper middle layer and including magnesium hydroxide and calcium carbonate dispersed within a thermoplastic resin.

A plastic fiber composite material/aluminum laminate having: at least one flat element made of aluminum and/or an aluminum alloy and a plastic fiber composite material comprising a matrix material which has a temporarily flowable and then hardened state initially or at least under a temperature effect. The at least one flat element has etched anchoring structures, the anchoring structures have steps and undercuts, and the anchoring structures are filled and/or enclosed by the matrix material of the plastic fiber composite material. Use of the plastic fiber composite material/aluminum laminate and a method for producing the plastic fiber composite material/aluminum laminate.

Provided are methods of forming stiffened stringer panels with integrated plank structures. A skin member having an inner surface is provided. A plank is positioned onto the inner surface of the skin member. The plank extends from a first side to a second side, and each laminate ply of the set of layered laminate plies is sized to form a geometric profile for each of the first side and the second side. Each laminate ply of the set of layered laminate plies is arranged to extend from the first side to the second side. A stringer is placed onto a support tool. The support tool, and the stringer thereon, is positioned upon an uppermost laminate ply of the set of layered laminate plies. The skin member, the plank, and the stringer are joined.
