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.
An orthopedic sheet comprising a pliant sheet of material having opposed side surfaces, said pliant sheet being impregnated with a viscous water-curable resin that cures when exposed to water a first triple-layered fabric structure overlaying one side surface of said pliant sheet, and a second triple-layered fabric structure overlaying the other side surface of said pliant sheet, each of said first and second triple-layered fabric structures having a front face, a back face and an intermediate portion interconnecting said front and back faces.
The orthopedic sheet comprising a pliant sheet having opposed side surfaces, said plaint sheet being impregnated with a viscous water-curable resin that cures when exposed to water, a triple-layered fabric material overlaying one side surface of said pliant sheet, a triple-layered fabric material overlaying the other side surface of said pliant sheet, and a closed-cell foam material interposed between one side surface of said pliant sheet and one of said triple-layered fabric materials, each of said triple-layered fabric materials having a front face, a back face and an intermediate portion interconnecting said front and back faces.
