““About half today’s production cost is for precursor material—96% of which is polyacrylonitrile made from oil (propylene) or natural gas (propane), both of which have volatile prices. Carbon-fiber manufacturers are starting to make their own precursors and expect to cut their costs by about 20%. But much cheaper precursors are emerging. Their strands of carbon atoms are commonplace; the trick is removing the other elements and forming the remaining carbon skeleton into long, pure strands. Solve those problems, and carbon fiber could be made from biomaterials like plant fibers, or even from recycled plastic trash. Oak Ridge National Laboratory (ORNL) believes these alternatives could potentially cut carbon-fiber costs by up to 90%,””
