Precision CNT Cutting Mechanism

NASA Langley Research Center has developed a simple mechanism for the clean cutting of high-strength and high-toughness carbon nanotube/poly-mer fiber composites on demand without high blade wear or replacement rates, and related high costs. The cutter is comprised of a set of blades both to score through any resin coating the fibers, and to provide an electrical current to cut through the fiber/composite reinforcement and any remaining resin in yarns, tapes, and sheets.
