A passive thermal management system and methods of using a thermoresponsive hydrogel coating configured to autonomously switch between a heating state and a cooling state based on ambient temperature. At temperature greater than a lower critical solution temperature of the thermoresponsive hydrogel, the thermoresponsive hydrogel coating becomes solar reflective and has enhanced radiative cooling ability to achieve daytime radiative cooling. At temperatures less than the lower critical solution temperature, the thermoresponsive hydrogel coating becomes transparent to facilitate absorption of solar radiation by sun absorber.

In a laminated steel plate in which steel plates are joined to both faces of a core layer, the core layer is formed of a meshed wire group formed using wires in a mesh form and a resin sheet, the wires forming the meshed wire group have a tensile strength of 601 MPa or higher, and an opening of the meshed wire group is equal to or less than ten times the thickness of the steel plates. By thus defining the tensile strength of the wires, light-weightness can be achieved compatibly with high rigidity and shock resistance, and by defining the opening of the meshed wire group, workability and shape stability after being processed can be improved.

Composite panel for air cargo containers including a fire resistant, closed cell foam core, a skin attached to at least one surface of the core formed by fire resistant fibers in a matrix resin, wherein the panel will contain an internal fire with temperatures of up to 1500° F. for a period of at least 4 hours.

Disclosed is an aqueous composition for surface coating, including: a main ingredient comprising a first compound having at least two functional groups selected from the group consisting of a carboxyl group, a hydroxyl group, an amino group and combinations thereof, per molecule; a curing agent comprising a second compound having at least two functional groups selected from the group consisting of an aziridine group, an isocyanate group, a carbodiimide group and combinations thereof, per molecule; and an aqueous solvent. Further, an automotive sheet using the aqueous composition for surface coating is disclosed.

A panel apparatus is described that includes a first sandwich panel and a second sandwich panel arranged substantially parallel to each other, and the first sandwich panel and the second sandwich panel each include a core material inserted between at least two skin layers. The panel apparatus also includes at least one mechanical fastener mechanically embedded into the first sandwich panel and the second sandwich panel. The at least one mechanical fastener at least extends through one skin layer and into the core material of the first sandwich panel and at least extends through one skin layer and into the core material of the second sandwich panel, and the at least one mechanical fastener is configured to accept insertion of an item. Methods of assembling the panel apparatus are also described.

A laminate of the present invention includes a first member which contains a thermoplastic polymer and through which laser light is transmitted and a second member which contains a thermoplastic polymer and absorbs laser light, wherein the first member is directly bonded to the second member, and A represented by the formula 1: A=−9×D+Wa−45 is more than zero. D represents a distance between a Hansen solubility parameter of the thermoplastic polymer of the first member and a Hansen solubility parameter of the thermoplastic polymer of the second member, and Wa represents work of adhesion calculated from each surface free energy of the first member and the second member. Such a first member and a second member are firmly bonded to each other without using a bonding sheet.

An improved fabric backing for the manufacture of glass-reinforced thermoplastic panels that exhibits significantly greater foam adhesion than its scrim counterpart. That fabric backing includes a plurality of looped section extending upwardly (and inwardly) from its base for enhancing adhesion thereto. The combination is subjected to lamination for making an improved glass-reinforced thermoplastic interior wall panel. That wall panel can be used in a storage unit, such as a refrigerated trailer, railcar, shipping container and/or box truck.

According to the present invention, provided are a molded article formed of a thermoplastic resin composition, the molded article having a mean deviation of surface frictional coefficient of 0.02 or more and 0.08 or less, a mean deviation of surface roughness of 4 μm or more and 12 μm or less, a work of compression of 0.05 gf.Math.cm/cm.sup.2 or more and 0.30 gf.Math.cm/cm.sup.2 or less, a bulk density of 0.20 g/cm.sup.3 or more and 0.70 g/cm.sup.3 or less, an area ratio of through-holes of less than 3%, and a thickness of 10 μm or more and 1000 μm or less, and a laminate having the molded article.

A method of producing a laminated article comprising placing a first metal skin, a core, and a second metal skin freely onto each other as discreet layers to provide a layered component; and forming the layered component into a shaped article via a die prior to producing a laminated article by applying pressure and heat to the shaped article, wherein at least the first skin moves relative to the core and/or second skin during the forming.

A method of making absorbent foam composites and absorbent foam composites produced therefrom. The method comprises casting an absorbent foam layer having a first side and a second side opposite the first side onto a barrier layer having a first side and second side opposite the first side, where the second side of the absorbent foam layer is in contact with the first side of the barrier layer; joining a second absorbent layer to the second side of the barrier layer before, during, or after the casting step; and breaching the barrier layer after the casting step so that the foam layer and second absorbent layer are in fluid communication. The absorbent foam composites can be used in a variety of applications, including personal hygiene articles, medical bandages, pet pads and agricultural pads.
