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.

Systems and methods are described herein for a composite building panel for use in a panelized structure. In some aspects, a composite building panel may include: a core defining a channel formed via subtractive manufacturing; a utility conduit placed or formed in and bonded to the channel and enclosed by the core, where the utility conduit exits the core along a first mating edge of the core; and first and second skin elements bonded to the core to form a layered structure. In some cases, the layered structure may also include a reinforced block coupled to at least the first fiber-reinforced skin element and defining part of the first mating edge, where the reinforced block defines a first portion of the first mating edge for mating with another composite building panel of the panelized structure.

The present invention further pertains a method for preparing a polymer foam laminate structure (1) and a composite component (1000) inter alia comprising the polymer foam laminate structure (1).

Low-density thermoplastic expandable microspheres are disclosed. Various low-density structures, in particular, sandwich panels, based on foam prepared from the low-density microspheres, are also disclosed. Process of preparing low-density polymeric microspheres, per se, and the corresponding low-density structures, based on the microsphere foam, are also disclosed.

The waterproof/breathable moisture transfer liner for a running and hiking shoe includes an inner liner selected from technically advanced fabrics which are carefully selected. A series of layers are provided outside the inner liner including foam material layers, breathable membranes, a supportive mesh or a moldable foam, and an outer shell fabric. The applicability of the liner to alpine, snowboard boots, cross country, hiking boots, protective gear and helmets, along with appropriate variations for each application.

A stretch laminate includes a first layer including an elastomer film, the first layer having a surface, and a second layer including a nonwoven material, the second layer having a surface that is attached to the surface of the first layer. The tensile behavior in the transverse direction of the stretch laminate is within about 2.5 N/cm of the tensile behavior in the transverse direction of the film at an engineering strain of about 1.5, and exists independent of mechanical activation. A method of making the stretch laminate and an absorbent article having at least one region defined by the stretch laminate are also provided.

A modular utility vehicle construct that is light weight yet robust is provided. The construct is formed with a composite open area core sandwich structure capable of withstanding typical wear and tear and environmental elements experienced by utility vehicle compartments. The use of the composite sandwich structure allows for replacement of traditional materials such as steel or aluminum, without a loss of strength, in a vehicle's containment construct while also reducing the overall weight of the vehicle and increasing the ability to customize the vehicle's utility features to suit the specific needs of the purchaser.

An insulated spa cover (10) contains a thermal insulating core (30), a top cover (150) with an average permeance of at least 57.2 nanograms/Pascal*seconds*square meters, and a hydrostatic head test value of at least 5,000 Pascals, a vapor barrier (130) and optionally a bottom sheet (140) apart from the vapor barrier. Venting pathways are defined around the thermally insulating core to facilitate escape of water vapor.

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.
