Abstract
Abstract Sheet-like compositions that can be used to form orthoses or orthopedic devices to conform to any shape of a body part. The sheet-like compositions include a pliant sheet impregnated with a viscous water-curable resin that hardens when exposed to water. Both sides of the pliant sheet are covered with individual composite fabric portions, each composite fabric being of a triple-layered structure comprising a front face, a back face and an interconnecting portion, each composite fabric having sufficient open knit or weave to allow the passage of air and moisture therethrough. In some embodiments, a closed-cell foam material may be interposed between one side of the pliant sheet and one of the composite fabric portions, and adhesive means may likewise be incorporated into the overall structure to prevent dislodgement of the pliant sheet, the fabric portions and the foam cell material.
