The raised woodgrain finish decorative material has a substrate, a first raised section provided on one surface of the substrate, and a second raised section provided on the one surface of the substrate in a different location than the location of the first raised section, wherein the length of the first raised section is longer than the length of the second raised section in the lengthwise direction of the substrate, and the height of the first raised section is higher than the height of the second raised section in the thickness direction of the substrate.

This disclosure relates to a fire-retardant composite material comprising a fibre-reinforced plastic covered by an aluminium foil and its application in passenger transport industries such as aerospace, railway or marine.

Fire-retardant panels that include: a frame with multiple holes that reduce heat conduction through the panel; or a frame that includes two portions separated by a layer of fire-resistant material (e.g., gypsum, calcium silicate, or gypsum board). Some embodiments include skins (e.g., sheet metal) or insulation (e.g., between skin and fire-resistant material, for instance, within the frame). In particular embodiments, the fire-resistant material is (e.g., midway) between: two skins, two layers of insulation, two portions of the frame, or a combination thereof. The portions of the frame can be: sheet metal, attached (e.g., screwed) to the skin(s) or to each other, or extend around the perimeter. The frame can include: various elongated members, (e.g., parallel) bends, or holes that are: in at least one row, elongated, or slots (e.g., parallel to each other or to the skin).

A prepreg is a blend of a fiber reinforcement, a matrix resin and a filler. Based on 100 parts by mass of the prepreg, the fiber reinforcement is 20-60 parts by mass, the matrix resin is 20-65 parts by mass, and the filler is 10-40 parts by mass. The filler is a flame-retardant organic microsphere or a blend of the flame-retardant organic microsphere and an inorganic filler, and the particle size of the filler is preferably 0.1 microns to 15 microns. A copper-clad laminate and a printed circuit board are also disclosed. In various embodiments, the stability of material properties of the prepreg can be improved, the prepreg manufacturing process is simplified, the prepreg production efficiency is improved. Due to the high production efficiency of the prepreg, the manufacturing cost of the prepreg, the copper-clad laminate and the printed circuit board can be reduced.

A copper-clad laminate includes an insulating substrate and a copper foil layer covering a surface of the insulating substrate. The insulating substrate includes at least one first insulating layer, and the first insulating layer is a blend of a surface fiber felt made of fibers and resin or a blend of a non-woven fabric-reinforced composite material and resin, and the copper foil layer is attached to an outer surface of the first insulating layer. The present disclosure also provides a printed circuit board, which is made from the copper-clad laminate of the present disclosure. The present disclosure also provides a method for manufacturing the printed circuit board. Compared with the related arts, the copper-clad laminate and the printed circuit board of the present disclosure have improved dielectric properties.

A laminate assembly includes a matrix layer and elongated, continuous strips of a conductive alloy. The matrix layer has opposite first and second sides connected by opposite first and second edges. Each of the first and second edges extends from the first side of the matrix layer to the opposite second side of the matrix layer. The elongated, continuous strips of the conductive alloy are disposed in the matrix layer between the first and second sides of the matrix layer. The elongated continuous strips continuously extend through the matrix layer from the first edge to the opposite second edge.
