Carbon Braid

For customized, laminated, and lightweight prosthetic sockets

Carbon braid is most commonly used in the fabrication process of custom definitive sockets for upper and lower limb prosthetics. Carbon braid allows the patient to have a lightweight yet rigid socket frame. When a technician fabricates a carbon frame he employs a hand lamination process of manually saturating the carbon braid with a hardening resin. Carbon braid is commonly available in weights of 12K standard, 6K lightweight, and 3K ultra lightweight.

Tech Tip– The rigidity of a carbon socket can be greatly increased or decreased by the number of layers used during the lamination process.
