This research focused on developing low-cost carbon fiber by utilisation of recycled textile grade acrylic fiber(RAF) replacing existing costlier special acrylic fibre-based precursors. RAF blended in low (10%wt) and high (50%wt) concentrations with high molecular weight Homo-PAN and stabilisation initiator additives i.e. terephthalic acid (TA) or graphene carboxylate (GRC) was wet spun into precursors. Precursors converted to carbon fibre as per the commercial PAN precursor process. This study demonstrated the development of carbon fibre with the desired properties and established the use of RAF and new additives for the stabilisation of carbon fibre.
