Abstract
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.
