The laminate of the present disclosure includes multiple glass ceramic layers each containing quartz and a glass that contains SiO.sub.2, B.sub.2O.sub.3, Al.sub.2O.sub.3, and M.sub.2O, where M is an alkali metal. The B concentration of a surface layer portion of the laminate is lower than the B concentration of an inner layer portion of the laminate.

Sound-absorbing material includes a monolithic main layer which is made of non-woven fiber fabric and has two opposite faces delimiting the thickness of the monolithic main layer. The monolithic main layer has a density gradient in the direction of its thickness. The monolithic main layer has a gradient in the fiber count in the direction of its thickness which decreases, passing from a first face to a second face of the monolithic main layer. The density gradient has an inverse trend with respect to the gradient in fiber count.

Thermally laminated foam boards, methods for making thermally laminated foam boards, apparatus for making thermally laminated foam boards, smaller foam pieces made from thermally laminated foam boards, methods for making smaller foam pieces from thermally laminated foam boards, parts made from thermally laminated foam boards, methods for making parts from thermally laminated foam boards, and tools for making parts from thermally laminated foam boards are disclosed. The thermally laminated foam boards are made by thermally bonding at least two polystyrene boards together.

In one embodiment, a method of forming an extruded board includes mixing a resin and a foaming agent, melting the mixed resin and foaming agent to form a uniformly colored extrudate, differentially expanding voids formed from the foaming agent within the uniformly colored extrudate by passing the uniformly colored extrudate through a breaker plate, forming a board with the differentially expanded voids and uniformly colored extrudate, and forming lightened portions on an outermost surface of the formed board.

A composite sheet material includes a cover sheet, a substrate and an adhesion promoting layer. The cover sheet has a cover sheet material. The substrate has a substrate material. The adhesion promoting layer is disposed between the cover sheet and the substrate. A first side of the adhesion promoting layer disposed towards the cover sheet has an affinity to bond with the cover sheet material. A second side of the adhesion promoting layer disposed towards the substrate has an affinity to bond with the substrate material.

A resin board structure includes a first member including a first metal film and one thermoplastic resin layer or a stack which includes two or more thermoplastic resin layers, and a second member including a second metal film. The first and second metal films are bonded together, and at least a portion the first metal film and at least a portion of the second metal film overlap each other. The first and second metal films are metallurgically bonded at an interface between the first metal film and the second metal film. The first member includes a first junction resin covering portion defined by a portion of a thermoplastic resin layer and overlapping a portion at which the first metal film and the second metal film overlap each other, and the first junction resin covering portion includes an uneven surface to reduce or prevent slippage due to ultrasonic vibration.

The present disclosure relates to a plastic-containing support for a decorated wall panel or floor panel, comprising a supporting material including a thermoplastic matrix material, in which a solid material with a particle size less than or equal to 800 m is embedded, wherein the support has a length, a width and a thickness, wherein the support has a density gradient along its thickness from a bottom surface to a top surface arranged on the opposite side to the bottom surface in such a manner, that the density of the supporting material averaged over a specified width or a specified length of at least 5 mm, preferably at least 20 mm, from the bottom surface to the top surface initially declines and then increases again.

To provide a palette, etc. on which an article is placed, including: a foamed synthetic resin-base material; and a polyurea-resin coating layer covering a front surface of the base material; and manufactured by a method including: injecting a polyurea-resin coating material onto a front surface of a foamed synthetic resin-base material; and drying the coating material after the injecting. The injecting may have injecting the coating material onto all surfaces of the base material. A thickness of the coating material formed on a front surface of the base material in the injecting may be controlled proportionally to an expansion ratio of the foamed synthetic resin. The thickness of the coating material may be controlled by adjusting a speed of conveyance of the base material and/or a distance between an injection port for the coating material and the base material. Heating-pressing the base material may further be included before the injecting.

Typical composite panels are brittle and unable to support transverse pressure loads that might be imposed on the panels. For example, the use of typical panels around fuel tanks of a vehicle are unable to support transverse pressure loads that might be imposed on the fuel tanks during a crash of the vehicle or a ballistic impact to the fuel tanks. In the embodiments described herein, panels include face sheets that are bonded to a foam core. The foam core includes a corrugated core sheet that is formed from a highly ductile material, such as Polyethylene or Aluminum. When a transverse pressure load is imposed on the panel, core crush of the foam occurs as the core sheet elongates from its original corrugated shape to a curve shape during deformation. This allows the panel to dissipate the energy of the transverse pressure load applied to the panel.
