A structural member including a lightweight core, one or more skins, and a crosslinking nanolayer interposed therebetween that results in significant mechanical strength in the structure. The core is a polymer of reduced density by way of included voids, such as an open or closed cell foam, honeycomb, or corrugated structure. The core polymer has a lower density and may have a higher softening or melting temperature than the polymer skin materials. The core may be discontinuous at the interface with the skin such that only a small percentage of the core surface is actually in contact with the skin compared to the overall area of the interface. The skin may be a thermoplastic layer that attaches to the core material. The skin may be a composite material including non-thermoplastic reinforcements. The crosslinking nanolayer is covalently bonded to the surface of the core material and provides molecular compatibility with the skin material.

A ceiling panel having a connection portion at one of end portions on both sides in a first direction of a panel body in a shape of a rectangular flat plate, the connection portion connecting with a connected portion of an adjacent ceiling panel. The connection portion is fixed to the end portion by a fastener, the fastener being fastened to an insertion part inserted into a layer of the panel body from a cut portion opening on a back face of the end portion so as to penetrate a securing part provided along the back face of the end portion.

A base paper (6), a picture pattern layer (7) provided on a surface (6a) side of the base paper (6), and foaming agents (8) arranged on a surface (7a) of the picture pattern layer (7) or in the picture pattern layer (7) are provided. In the foaming agents (8), the average particle diameter after foaming is set to 15 m or more and 250 m or less and the foaming start temperature is set to 100 C. or more and 220 C. or less.

Disclosed herein is a binder system for nonwoven fiber mats that provides desirable properties to the nonwoven mat including desirable porosity, desirable surface properties e.g., desirable wettability and/or moisture resistance, and enhanced tensile strength. The system includes a two-part binder that includes (1) a formaldehyde-free carbohydrate-based binder and (2) a formaldehyde-free hydrophobic acrylic-based hinder.

The present invention relates to composite materials and the use thereof as energy resistant, for example blast-resistant, materials. Preferred aspects of the invention relate to layered composite panels comprising solid foam materials which have both a blast attenuation function and an anti-ballistic function. In further aspects, the invention provides novel composite panels which are suitable for use as blast resistant and/or anti-ballistic materials. In some examples described, the layered composite panel comprises a polymeric material (10) bonded to a first solid open-cell foam panel (12), and a cured polymeric material (14) penetrates a surface of the first solid open-cell foam panel (12).

A hybrid loader boom arm assembly for a loader work vehicle includes an arm assembly. The arm assembly includes a hollow first beam formed from a lightweight material and a block formed from a second lightweight material. The block has a first block end received within a first end of the first beam. The arm assembly includes at least one first steel reinforcing plate coupled to the first beam at the end, and at least one connecting plate coupled to the at least one first reinforcing plate.

A panel and a method of making a panel are provided. The panel comprises a cured polymeric foam layer that is formed by application of a foam composition to an edge surface of the panel and then shaped and cured. The panel comprises man-made vitreous fibre or wood wool cement.

The present invention provides a polishing roll capable of, for example, realizing three-dimensional polishing of hard materials such as sapphire glass at a high removal amount. The polishing roll is a cylindrical polishing roll capable of rotating about a central axis, characterized in that the polishing roll includes a core part serving as a central axis to which torque is applied, an intermediate part having a cross-section concentric with the core part, and a polishing part disposed on the outer peripheral surface of the intermediate part, and the intermediate part is made of a cushion material that is softer than the polishing part.

An adhesive article is described comprising a foamed adhesive layer and a non-foamed adhesive layer. The adhesive of each adhesive layer comprises a tetrahydrofurfuryl (meth)acrylate copolymer; an epoxy resin; a polyether polyol; and optionally a hydroxy-functional film-forming polymer. The adhesive may be used in structural and semi-structural bonding applications and is designed to fail cohesively.

A system and method for dielectric bonding including a dielectric heater having a pair of opposing electrode plates, a nest removably coupled to a first electrode plate of the pair of electrode plates, and an interchangeable electrode assembly removably coupled to a second electrode plate of the pair of electrode plates. The nest having a plurality of cooling channels defined in a body thereof in which a cooling fluid circulates to cool a material assembly that is supported by the nest. The interchangeable electrode assembly having a plurality of concentrator members that are configured to concentrate energy from a voltage source in predetermined locations on the material assembly.
