Disclosed here is a composite filter media having at least one nanofiber layer bonded to a substrate layer, the at least one nanofiber layer optionally having a plurality of nanofibers having a geometric mean diameter of less than or equal to 0.5 μm, the at least one nanofiber layer having a thickness of about 1-100 μm.

A repulpable insulated container assembly having a container formed of paper such as corrugated cardboard or varying paper materials and defining an interior; and a repulpable insert placed within the interior of the container and formed of a first paper layer; and a paper fiber pad coupled to the first paper layer.

A filter medium according to one embodiment of the present invention comprises: a first support having a plurality of pores; a nanofiber web comprising nanofibers disposed on upper and lower portions of the first support and forming a three-dimensional network structure, and a hydrophilic coating layer formed on at least a part of an outer surface of the nanofibers, wherein the hydrophilic coating layer is formed of a hydrophilic coating composition comprising a hydrophilic polymer compound having at least one functional group selected from a hydroxyl group and a carboxyl group and a crosslinking agent comprising at least one sulfone group; and a second support having a plurality of pores interposed between the first support and the nanofiber web.

A composite cooling film including non-fluorinated organic polymeric layer, a metal layer disposed inwardly of the non-fluorinated organic polymeric layer, and an antisoiling, ultraviolet-absorbing hardcoat layer that is disposed outwardly of the non-fluorinated organic polymeric layer.

A fiber composite structure includes a base structure being formed of a first fiber composite material that includes first fiber bundles embedded in a first matrix material, wherein the base structure includes an opening defined by first fiber bundles which include first sections and a second section that continuously or uninterruptedly interconnects the first sections, wherein the second section forms a bay that defines a part of the circumference of the opening. The fiber composite structure further includes a functional structure positioned in the opening of the base structure and joined with the first fiber composite material of the base structure.

A hot press cushioning material includes a cushioning material body in the form of a plate; and surface materials provided on the front and back sides of the cushioning material body. The surface material includes a core layer composed of a heat resistant fiber material for a nonwoven structure, and a front-side resin layer covering the entire front side of the core layer. The core layer has an air permeability of 5 cm.sup.3.Math.cm.sup.−2.Math.s.sup.−1 or less and a bulk density of 0.8 g/cm.sup.3 or more.

Ballistic resistant composite materials having high positive buoyancy in water are provided. More particularly, provided are foam-free, buoyant composite materials fabricated using dry processing techniques. The materials comprise fibrous plies that are partially coated with a particulate binder that is thermopressed to transform a portion of the binder into raised, discontinuous patches bonded to fiber/tape surfaces, while another portion of the particulate binder remains on the fibers/tapes as unmelted particles. The presence of the unmelted binder particles maintains empty spaces within the composite to materials which increases the positive buoyancy of the composites in water.

Provided is a jig which assists in the adhesion of a thin-film sheet to an adhesion target surface (skin etc.), and which can easily adhere the thin-film sheet to the adhesion target surface. The jig includes: a base part having a first surface; and a porous hydrophilic film that is adhered to the first surface and has fine pores with a predetermined porosity, wherein the porosity is 35% to 55% inclusive. The hardness of the base part is preferably 4-20 inclusive. In addition, it is preferable that the base part and the hydrophilic film have transparency.

Hybrid fibrous composite materials incorporating at least two different fabric components and a multicomponent adhesive system for adhering the fabric components together. The adhesive system enhances the bond strength between the fabric components, which would otherwise easily delaminate from each other and peel apart. The components of the adhesive system bond strongly to each other as well as to the fabric elements.

A floor, wall or ceiling panel comprises a core and a decorative top layer provided on the core. The core comprises a magnesium oxide-based board material, and wherein the aforementioned panel, on at least two opposite edges, is provided with coupling means allowing that two of such panels can be interlocked at the respective edges.
