Carbon nanofibers based carbon–carbon composite fibers
Discover Nano, 2023 Textile grade polyacrylonitrile (PAN) was used as a precursor material for carbon fiber preparation. E-beam irradiated polyacrylonitrile grafted carbon nanofibers were dispersed in polyacrylonitrile solution (dissolved in dimethyl formamide).

A mechanism study of acid-assisted oxidative stabilization of asphaltene-derived carbon fibers [PDF]
, 2021 The development of inexpensive carbon fiber precursors is necessary to meet the future demands of carbon fibers. This work shows how asphaltenes, which are obtained as a by-product in bitumen production, can play an important role as such inexpensive ...

Converting PBO fibers into carbon fibers by ultrafast carbonization
Carbon, 2020 Abstract We report an ultrafast transformation of poly(p-phenylene-2,6-benzobisoxazole) (PBO) fibers into carbon fibers (CFs) by direct carbonization that eliminates high-cost oxidation in traditional CF conversion. Ultrafast heating and cooling render PBO-derived CFs superlative mechanical properties.
