Highly-filled polyurethane composites with fiber reinforcement
Composite panels and methods of preparation are described herein. In some embodiments, the composite panel can include a first fiber reinforcement, a polyurethane composite having a first surface and a second surface opposite the first surface, wherein the first surface is in contact with the first fiber reinforcement; and a cementitious material adjacent the first fiber reinforcement opposite the polyurethane composite. The polyurethane composite can be formed from (i) one or more isocyanates selected from the group consisting of diisocyanates, polyisocyanates, and mixtures thereof, (ii) one or more polyols, and (iii) a particulate filler. The fiber reinforcement can be formed from a woven or non-woven material, such as glass fibers. The composite panel can further include a material, such as a second fiber reinforcement and a cementitious layer, in contact with the second surface of the polyurethane composite. Articles comprising the composite panels are also disclosed.
Thermal Vacuum Insulation Element
A thermal vacuum insulation element (10) comprising a first planar limiting part (12) and a second planar limiting part (14). The limiting parts are spaced apart from each other and define an evacuated space (16) between them. The evacuated space (16) is sealed by means (26) for sealing. The vacuum insulation element includes first support elements (18) extending away from the first limiting part (12) into the evacuated space (16) and second support elements (20) extending away from the second limiting part (14) into the evacuated space (16), the limiting parts (12, 14) being arranged with the support elements (18, 20) such that the first support elements (18) and the second support elements (20) protrude beyond and are spaced from each other. The first support elements (18) are spaced from the second limiting part (14), and the second support elements (20) are spaced from the first limiting part (12). A fiber structure (22) interconnects the first support elements (18) and the second support elements (20). The fiber structure (22) has a low thermal conductivity and is configured to absorb at least the pressure caused by the vacuum on the first and second limiting parts (12, 14).
THERMOPLASTIC ELASTOMER COMPOSITION, LAMINATE STRUCTURE AND METHOD FOR PRODUCING SAID LAMINATE STRUCTURE

The content of the acrylic block copolymer (I) is 70 to 300 parts by mass with respect to 100 parts by mass of the hydrogenated block copolymer (II); the hydrogenated block copolymer (II) is a hydrogenated product of a block copolymer (P) including a polymer block (A1) containing structural units derived from an aromatic vinyl compound, and a polymer block (B1) containing 1 to 100 mass % of structural units (b1) derived from farnesene and 99 to 0 mass % of structural units (b2) derived from a conjugated diene other than farnesene, the mass ratio [(A1)/(B1)] of the polymer block (A1) to the polymer block (B1) being 1/99 to 70/30; and the hydrogenation ratio of carbon-carbon double bonds in the polymer block (B1) is 50 to 100 mol %.
Segmented flexible gel composites and rigid panels manufactured therefrom
The present invention describes various methods for manufacturing gel composite sheets using segmented fiber or foam reinforcements and gel precursors. Additionally, rigid panels manufactured from the resulting gel composites are also described. The gel composites are relatively flexible enough to be wound and when unwound, can be stretched flat and made into rigid panels using adhesives.

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.
Absorbent structures with high absorbency and low basis weight
Absorbent product including a laminate of at least two plies, wherein the absorbent product has a measured Valley Volume parameter greater than 11 microns and a Pit Density of greater than 25 pockets per sq. cm.
SKIN MATERIAL, INTERIOR MATERIAL, AND METHOD FOR MANUFACTURING INTERIOR MATERIAL
For the purpose of providing a skin material that is easily bonded to a base material, an interior material including the skin material, and a method for manufacturing the interior material, a skin material includes a base cloth layer and a design layer. The base cloth layer includes a surface fabric and a back fabric, and a binding yarn that binds the surface fabric and the back fabric. The binding yarn is erected between the surface fabric and the back fabric to form a void inside the base cloth layer. An embossed pattern is formed in a concave shape on the skin material from the design layer side. A thin portion is formed in a band shape in a peripheral edge portion of the skin material. The skin material is bonded to the base material to obtain an interior material.
