Flooring and floor panels are described that include a multi-layer tape. The multi-layer tape can include two or more layers at least one of which can include a unidirectional orientation of fibers. In some configurations, the panels can include a tape with multiple layers where each layer of the tape includes a unidirectional orientation of fibers, which may be the same or may be different. Vehicles and other devices including the panels are also described.

An embedded light source in a composite panel. A first electrode and a second electrode are associated with a first layer of material. A light source is positioned in electrical communication with the first electrode and the second electrode. An assembly comprising the first layer of material, the first electrode, the second electrode, and the light source is processed to form a multilayer panel with an embedded light source.

There is provided an article that includes a polymeric layer disposed on and covering a first major surface of an porous layer, an adhesive layer disposed on a second major surface of the elastic layer opposite the polymeric layer; and a liner disposed on a major surface of the polymeric layer opposite the first major surface of the elastic layer. The polymeric layer and the porous layer together form an air and water barrier that is water vapor permeable. The liner is water vapor impermeable. In a preferred embodiment the polymeric layer comprises a polyoxyalkylene polymer having at least one end group derived from an alkoxy silane. A method of applying the article to a surface of a building component is also provided.

A piston for a heavy duty diesel engine including a composite layer forming at least a portion of a combustion surface is provided. The composite layer has a thickness greater than 500 microns and includes a mixture of components typically used to form brake pads, such as a thermoset resin, an insulating component, strengthening fibers, and an impact toughening additive.

A method of forming a polyisocyanurate foam board includes providing a polyol and adding an isocyanate to the polyol to form a polyisocyanurate foam. A first inner surface of a first facer material is treated with a first flow of hydroxyl containing molecules. A second inner surface of a second facer material is treated with a second flow of hydroxyl containing molecules. The polyisocyanurate foam is coupled to the first treated inner surface and the second treated inner surface such that the polyisocyanurate is sandwiched between the first facer material and the second facer material, thereby exposing opposing outer surfaces of the polyisocyanurate foam to the hydroxyl containing molecules. A density of a medial portion of the polyisocyanurate foam is greater than a density of the polyisocyanurate at the opposing outer surfaces.

Provided is a foam sheet that can raise an electrostatic capacitance at the time of compression, and hence can improve sensitivity when used for an electrostatic capacitance sensor. The foam sheet includes: a foam layer; and a pressure-sensitive adhesive layer arranged on at least one side of the foam layer, wherein the foam sheet has a dielectric constant increase amount Q-P at 10% compression of 0.2 (F/m) or more, where P (F/m) represents a dielectric constant of the foam sheet immediately after the foam sheet has been left at rest under conditions of a temperature of 23° C. and a humidity of 50% for 2 hours, and Q (F/m) represents a dielectric constant of the foam sheet at a time when the foam sheet is compressed by 10% immediately after being left at rest under the conditions of a temperature of 23° C. and a humidity of 50% for 2 hours.

Provided is a display device using an adhesion control layer, which has excellent scratch-resistance, easily discharges air bubbles, allows proper attachment and detachment, and is stably attached regardless of whether a surface is flat or curved.
