Investigation of the Influence of Hexabenzocoronene in Polyacrylonitrile-Based Precursors for Carbon Fibers

For several decades, carbon fibers have been used for lightweight engineering in aircraft automotive and sports industries, mostly based on high-quality polyacrylonitrile (PAN). We investigated a novel PAN-based precursor fiber (PF) modified with polycyclic aromatic hydrocarbon, namely hexabenzocoronene (HBC), which is expected to improve the thermal conversion process create (CF) enhanced mechanical properties. this purpose, PF spun-like homopolymeric were thermally stabilized carbonized continuous lab-scale plants. The effect of additive HBC processes, diameter shape, density, properties investigated. results showed that seems support stabilization reactions, HBC/PAN-based show potentially higher stretchability fiber. CF an improvement Young’s modulus about 25% at same tensile strength compared unmodified CF, resulting from crystalline orientation. high potential HBC/PAN energy-efficient production. In particular, influence under optimized conditions, as well possibility use low quality PAN, need be further
