Described herein is a building panel and related building systems, the building panel having a first major surface opposite a second major surface, the building panel comprising a core comprising a first body comprising a first fibrous material; and a second body comprising a second fibrous material, a veneer facing layer coupled to the core, the veneer facing layer comprising a plurality of perforations.

A high-adsorption-performance nanofiber filter medium includes a support material and a composite nanofiber filtration layer that includes multiple nanometer composite nanofiber layers deposited and stacked on the support material. The nanometer composite nanofiber layer includes first, second, and third nano-powder composite nanofibers, which are uniformly mixed by means of an airflow or are sequentially laminated to form the nanometer composite nanofiber layer. The nanometer composite nanofiber layer formed through sequential lamination includes first, second, and third nanofiber layers. The first nanofiber layer includes multiple first nano-powder composite nanofibers. The second nanofiber layer is stacked on the first nanofiber layer and includes multiple second nano-powder composite nanofibers. The third nanofiber layer is stacked on the second nanofiber layer and includes multiple third nano-powder composite nanofibers. The composite nanofiber filtration layer is formed of multiple nanometer composite nanofiber layers, so that the high-adsorption-performance nanofiber air filter medium shows improved performance.

The present disclosure is directed to a tailgate protector for a vehicle, wherein the protector comprises a pressure absorbent material which has been attached to a body of the protector with an adhesive, wherein the material having pressure absorbent property is a fabric or rubber and provides a soft padded area for protecting a user from injury or discomfort, and the adhesive is a pressure sensitive adhesive comprising styrene, and the body is formed from a resin.

An insulated panel assembly having improved insulative R-value. The insulated panel assembly comprises a cover panel, a first insulation layer, and at least one additional insulation layer, wherein the at least one additional insulation layer has a higher R-value than the first insulation layer. The first insulation layer is secured to the cover panel. The first insulation layer further forms at least one recessed portion. The at least one additional insulation layer is positioned in the at least one recessed portion of the first insulation layer. Examples of the at least one additional insulation layer may include vacuum insulated panels and modified atmosphere insulation panels.

The present invention relates to a flexible ballistic armor apparatus for deflecting high velocity firearm, fragmentation, or shrapnel projectiles with a flexible armor unit. The apparatus minimizes the deterioration of the armor when subjected to shock waves or shear forces of a ballistic impact. The present invention also relates to the use of a flexible armor unit with soft body armor, a vehicle, a vessel, an aircraft or in structural applications.

A barrier is provided to be placed between a first region and a second region, to prevent passage of pathogens between the first and second regions. The barrier includes a single ply layer treated with pathogenicidal components. The single ply layer includes a first side directed toward the first region, and includes an outer surface coated with the pathogenicidal components such that pathogens in the first region are incident on the outer surface of the first side. The single ply layer also includes a second side directed toward the second region, and includes an outer surface coated with the pathogenicidal components such that pathogens in the second region are incident on the outer surface of the second side. The pathogenicidal components coated on the outer surfaces of the first and second side deactivate the pathogens incident on the outer surface of the respective first and second sides.

A pad holder includes a base panel. The base panel includes a panel perimeter edge that defines a panel face. A lip material is connected to the panel face at a connection. A lip of the lip material extends from the connection towards a center of the panel face. The lip includes a lip perimeter edge, and the lip, panel face, and the connection collectively define an envelope. The envelope includes an opening defined by the lip perimeter edge. The envelope is sized to receive a liquid absorbent pad where the lip overlaps edges of the liquid absorbent pad when the liquid absorbent pad is disposed within the envelope.

A multi-layer ballistic woven fabric, including an upper woven layer having upper warp yarns and upper weft yarns that are interwoven together to form the upper woven layer. The multi-layer ballistic woven fabric also includes a lower woven layer having lower warp yarns and lower weft yarns that are interwoven together, and a plurality of securing yarns, each securing yarn interwoven with at least some of the upper yarns and some of the lower yarns so as to secure the upper and lower woven layers together. At least one of the securing yarns is woven underneath a first lower weft yarn, then above a second upper weft yarn adjacent the first lower weft yarn, then underneath a third lower weft yarn adjacent the second upper weft yarn and then above a fourth upper weft yarn adjacent the third lower weft yarn. The multi-layer ballistic woven fabric is formed by interweaving the securing yarns with the warp yarns and weft yarns as the upper woven layer and lower woven layer are made.

A cleaning device for removing marks from a surface includes a body of melamine foam sponge having a front side and a rear side opposed to the front side, and a holding layer secured to the rear side of the body of melamine foam sponge to prevent relative movement therebetween. The holding layer is preferably a cloth and more preferably natural or synthetic chamois which can be used to wipe and/or buff the surface after rubbing the body of melamine foam sponge on the surface to remove at least one surface mark. The body of melamine foam sponge can be pre-moistened with a liquid such as a disinfecting solution.

The present invention provides a resin composition containing an epoxy compound A having a specific structure having an aromatic ring, and having an epoxy equivalent in the range of from 500 to 10,000 g/eq, and an epoxy compound B having an epoxy equivalent in the range of from 100 to 300 g/eq, and a bonding agent containing the resin composition. Further, the present invention provides a cured product containing resin particles and a matrix resin, wherein the resin particles are a cured product of an epoxy compound A having a specific structure having an aromatic ring, and having an epoxy equivalent in the range of from 500 to 10,000 g/eq, and the matrix resin is a cured product of an epoxy compound B having an epoxy equivalent in the range of from 100 to 300 g/eq, and a laminate having a substrate and the cured product.
