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 μm or less.

Provided is a functional laminate including a porous intermediate layer having air permeability laminated between a porous surface layer and a resin foamed layer, the porous intermediate layer having an affinity to a foaming resin forming the resin foamed layer.

A display device including a flexible base substrate; a pixel circuit and a light emitting structure sequentially disposed on the flexible base substrate; and a stretchable film attached on a bottom of the flexible base substrate. The stretchable film includes a first region and a second region, which are divided according to curvatures of an object, and at least one of different patterns and different disposed structures are arranged in each of the first region and the second region.

A method produces a high-pressure gas storage container that includes a liner and a reinforcing layer. The liner houses a high-pressure gas. The reinforcing layer is formed by winding a plurality of strip-shaped reinforcing members around an outer perimeter surface of the liner. The method includes irradiating plasma on at least a portion of the reinforcing fibers, and adjusting an irradiation intensity of the plasma such that an irradiation amount of the plasma with respect to the reinforcing fibers becomes constant in accordance with changes in a transport speed of the reinforcing fibers.

Laminated glass for vehicle includes a region with a breaking stress measured by a method described in ISO 1288-5 (2016) of 100 MPa or more and 600 MPa or less. A percentage of the region is greater than or equal to 90% of a see-through region.

The present invention relates to a multi-layer polypropylene film comprising: A base layer of polypropylene (2); Optionally, a tie layer (3) comprising a blend of polypropylene and an sacrificial engineering thermoplastic; A top layer (1) comprising film having a structured surface with water contact angles (WCA) superior to 104.5°, preferentially superior to 110°, more preferentially uperior to 120°, more preferentially superior to 130°; Wherein the top layer comprises a blend 20 to 40 wt % of polypropylene and 60 to 80 wt % of said engineering thermoplastic and in which the engineering thermoplastic has been selectively etched in order to create the said structured surface.

There is provided a skin foam-in-place foamed article comprising a pad (15) and a bag-like outer material (20) covering the pad (15). The outer material (20) has a top layer (21) and a liner layer (22) made of a foamed resin. The liner layer (22) has a closed cell structure. A pad-side skin layer (27a) having a density higher than that of a bulk layer (26) is provided on the liner layer (22), on a side of the pad (15). A corona treatment is applied to the pad-side skin layer (27a).

A cover panel, for at least partially transparently covering at least one display instrument in a vehicle, has a microstructure applied on at least one surface. The microstructure is suitable for scattering visible light which is incident on the cover panel. The at least one window region of the cover panel is cutout from the microstructure. A method for manufacturing such a cover panel uses a molding tool with an applied microstructure matrix for forming a microstructure on a part of the molding tool which is assigned to a surface of a molded cover panel. The parts of the molding tool which are assigned to window regions are cut out from the microstructure matrix.

Disclosed is a dpackaged product comprising a particulate, savoury food material, the packaging comprising a multi-layer packaging film which comprises: an inner layer comprising polypropylene; an outer layer comprising polypropylene; and an intermediate layer comprising polypropylene.

A method of manufacturing at least one structural panel (20) for an engineering structure comprises conveying a layered structure (40) through a roller assembly comprising at least one pair of heating rollers (50) and at least one pair of cooling rollers (52), where the cooling rollers are at a lower temperature than the heating rollers. The layer structure comprises a thermoplastic foam layer 24 and at least one skin layer (22). The heating rollers 0 heat the skin layer (22) to melt at least part of the foam layer (24) adjacent to the skin layer (22) and bond the foam layer (24) to the skin (22). The cooling rollers (52) cool the layered structure (40) so that the thermoplastic resolidifies, retaining its bond with the skin to form the bonded panel (20). This approach greatly reduces manufacturing costs for structural panels.
