One of the challenges in carbon fiber production centers around the high cost of raw materials required for fiber precursors or complex production processes involving multiple steps. This research paper delves into the utilization of asphaltene sourced from Alberta oil sands as an alternative precursor material that is low cost for carbon fiber production. We investigated the carbon fiber production process using a blend of different asphaltene types via melt-spinning technology. Carbon fibers produced from asphaltene-based precursors exhibit an average diameter of 12.66 ± 3.06 μm, an ultimate tensile strength (UTS) of 524.07 ± 218.53 MPa, an elastic modulus of 34.68 ± 15.61 GPa, and a strain at the UTS of 2.48 ± 0.97%. The results validate the viability of asphaltene as a precursor fiber and highlight the potential of carbon fibers.
碳纤维生产面临的挑战之一在于纤维前驱体所需原材料成本高昂，或涉及多步骤的复杂生产过程。本研究论文深入探讨了将源自阿尔伯塔油砂的沥青质用作碳纤维生产低成本替代前驱体材料的情况。我们通过熔融纺丝技术，使用不同类型沥青质的混合物研究了碳纤维生产过程。由沥青质基前驱体制备的碳纤维平均直径为12.66±3.06μm，极限抗拉强度（UTS）为524.07±218.53MPa，弹性模量为34.68±15.61GPa，UTS处的应变为2.48±0.97%。结果验证了沥青质作为前驱体纤维的可行性，并突出了碳纤维的潜力。
