Enhanced Strength Carbon Nanotube Yarns
Superior weight/strength ratio Significantly enhanced strength and toughness
Researchers at UCLA have developed a novel CNT/resin composite material that approaches the strength of Kevlar at a lighter weight. This new method involves compounding thousands of CNTs into a single unit CNT yarn on the millimeter scale, followed by surface chemistry performed on the CNT yarn to allow for resin compatibility, and infusion of resin by a Vacuum Assisted Resin Transfer Molding (VARTM) process. This method can drastically reduce the viscosity of the resin and allow it to fully permeate in between the CNTs within the yarn. The resulting CNT/resin composite has a superior weight/strength ratio than that of materials such as steel, aluminum, Kevlar, and carbon fibers, and thus has the potential to replace these materials in the automotive and aeronautic industry.

Title: Enhanced strength carbon nanotube yarns and sheets using infused and bonded nano-resins
Usefulness: Enhanced strength carbon nanotube yarns and sheets using infused and bonded nano-resins
Summary: For making improved strength carbon nanotube yarn or tows, useful as structural components (claimed) in producing performance enhancements in various commercial products such as sporting goods (bats, arrows, hockey sticks, golf shafts and heads), aerospace products (struts, cowls, optic mounts, fuselage, solar sails, antennas and drone structures), and vehicle armor.
Novelty: Making improved strength carbon nanotube yarn used in e.g. sporting goods involves surface-activating unspun yarn via atmospheric pressure plasma to produce open bonds, infusing nano-resin into all voids, tightening the fibers and curing
