A footwear sole structure having a fluid-filled chamber including a tensile member is provided. The fluid-filled chamber includes a first barrier sheet, a second barrier sheet and the tensile member. The first barrier sheet is formed from a first thermoplastic material. The second barrier sheet is attached to the first barrier sheet and is formed from a second thermoplastic material. The first barrier sheet and the second barrier sheet cooperate to define an internal cavity. The tensile member is disposed within the internal cavity and is formed from a third thermoplastic material. A first weld attaches the first barrier sheet, the second barrier sheet, and the tensile member together by melding the first thermoplastic material of the first barrier sheet, the second thermoplastic material of second barrier sheet, and the third thermoplastic material of the tensile member.

Further, it relates to a process for the production of the thermal insulation board (IB) and to the use of the thermal insulation board (IB) and of the thermal insulation system (IS) for the thermal insulation of buildings, parts and/or elements of buildings.

The present disclosure relates to a composite membrane formed by lamination of two or more separate porous polymeric layers, as well as to a method and system for lamination. Advantageously, the resulting composite is a single layer, being difficult to separate into its component layers, yet effectively maintains the filtering capabilities of the component layers when not laminated.

Energy dampening and/or dispersing systems may include a gel member having a top surface and a bottom surface, an aerated gel member having a top surface and a bottom surface, and the top surface of the aerated gel member secured to the bottom surface of the gel member. In some embodiments, the energy dampening and/or dispersing systems may include a support structure secured to the gel member, and a cover extending over the top surface of the support structure and the bottom surface of the aerated gel member. The energy dampening and/or dispersing systems may be operable in ballistic garments, footwear, sporting goods, and vehicles.
