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.
