Provided are a composite material and a preparation method therefor. The composite material comprises: a base layer; a first plant fibre fabric located on the upper surface of the base layer; optionally, a second plant fibre fabric located on the lower surface of the base layer; and resins present in each layer. The composite material has a decorative performance and an improved mechanical performance.

The present invention relates to a carrier foil-attached metal foil including a release layer having a specific composition and structure, a method of manufacturing the carrier foil-attached metal foil, and a laminate for forming a printed circuit board including the carrier foil-attached metal foil. The laminate for forming a printed circuit board according to the present invention comprises the carrier foil-attached metal foil, so that a defect rate can be minimized.

A wet friction material includes a base including a matrix of fibers and filler particles embedded in the matrix of fibers; a binder embedded in an interior of the base; and a quaternary ammonium salt containing coating on an outer surface of the base. The quaternary ammonium salt containing coating can include a quaternary ammonium salt and a solution binder.

The present invention relates to a method of producing a glued wood product for use in construction, comprising the steps of: providing at least two wooden pieces each piece comprising at least one joining face; creating a groove in at least one of said joining faces where the groove is arranged between a pair of peripheral edges; applying adhesive onto at least one of the joining faces of at least a first of said two wooden pieces; arranging said first wooden piece so that the joining face which comprises the applied adhesive meets a corresponding joining face of said second wooden piece, wherein at least one of said two joining faces comprises said groove; pressing the two joining faces towards each other so that the adhesive is compressed between said two wooden pieces, and maintaining said pressing for a sufficient time to bond the wooden pieces to each other; wherein the applied pressing force is strong enough to force the wood tissue to collapse at a contact area until the pressure force is transmitted primarily through the adhesive, wherein said contact area is defined by the surface area whereat the two joining faces of said wooden pieces contact each other upon being pressed together.

A self-expiring band structure is activated upon the contacting of two chemical constituents together. This contacting may be performed by the attachment action of the band or independently thereof. After a time duration has passed, the coaction of the chemical constituents result in a visually perceptible change can alert others to the fact the band has expired. These bands may be both printable, such as by a printer or other machine printing, as well as time-expiring making them a very versatile product that offer heightened security at the price point closer to that of a disposable item because they do not require complex infrastructure for validation.

The present invention relates to a multilayer structure including a base (X) and a layer (Y), wherein the layer (Y) includes an aluminum-containing compound (A) and a phosphorus compound (BH) in which a phosphorus atom having at least one hydroxy group and a polar group are bonded via an alkylene chain having 3 to 20 carbon atoms or a polyoxyalkylene chain based on an alkylene having 3 to 20 carbon atoms, and the aluminum-containing compound (A) is a compound (Ab) including a reaction product (D) of an aluminum-containing metal oxide (Aa) and an inorganic phosphorus compound (BI).

A fibrous structure comprising first and second plies. The first ply comprises a first textured substrate comprising a first side comprising first discrete regions and a first continuous region extending between the first discrete regions, each first discrete region comprising an outer section and sidewall sections extending outwardly from the adjacent first continuous region to the outer section; a second side comprising first discrete portions corresponding to the first discrete regions and a first continuous portion corresponding to the first continuous region; and first polymer particles deposited on at least one of the first side or the second side. When the first polymer particles are deposited on the first side, the first polymer particles are substantially deposited on the outer sections of the first discrete regions and do not extend to the adjacent first continuous region. When the first polymer particles are deposited on the second side, the first polymer particles are substantially deposited on the first continuous portion and do not extend to the adjacent first discrete portions. At least a section of each of the first polymer particles defines a raised edge. The second ply comprises a second substrate joined to the first textured substrate.

A flexible display apparatus comprises a glass substrate including a flat surface and a glass etching surface that is curved, and a flexible display panel including a bending portion on the glass etching surface.

A graphite sheet having a ratio of thermal diffusivity in horizontal and vertical directions of 300 or more is disclosed. Also, a graphite sheet having a ratio of thermal diffusivity in a vertical direction of 2.0 mm.sup.2/s or less is disclosed. The graphite sheet has excellent thermal conductivity in horizontal and vertical directions and excellent flexibility at the same time and can be produced at low manufacturing cost, thereby holding an economic advantage.

A method of installing a roof system includes providing a first membrane composite; adhesively securing the first membrane composite to a roof surface through a UV-cured pressure-sensitive adhesive layer; providing a second membrane composite; adhesively securing the second membrane composite to the roof surface through a UV-cured pressure-sensitive adhesive layer, where the second membrane composite is positioned adjacent to and partially overlapping a lap area of the first membrane composite; and adhesively securing the second membrane composite to a first planar surface of the first membrane composite along a primer layer through the UV-cured pressure-sensitive adhesive layer disposed on the second membrane composite.
