Making stronger carbon-fiber precursors

Carbon fiber–reinforced polymers are used to create lightweight, high-strength structures such as airframes. More than 96% of commercial carbon fiber is derived from high-temperature heating (up to 1700°C) and stretching of a precursor fiber made from polyacrylonitrile (PAN) ([ 1 ][1]). In this process, PAN cyclizes to create a ladder structure, which is then carbonized to create the final…
