Although polyacrylonitrile (PAN)-based carbon fibers have been successfully commercialized owing to their excellent material properties, their actual mechanical performance is still much lower than the theoretical values. Meanwhile, there is a growing demand for the use of superior carbon fibers. As such, many studies have been conducted to improve the mechanical performance of carbon fibers. Among the various approaches, designing a strong precursor fiber with a well-developed microstructure and morphology can constitute the most effective strategy to achieve superior performance. In this review, the efforts used to modulate materials, processing, and additives to deliver strong precursor fibers were thoroughly investigated. Our work demonstrates that the design of materials and processes is a fruitful pathway for the enhancement of the mechanical performance of carbon fibers.
尽管基于聚丙烯腈（PAN）的碳纤维因其优异的材料性能已成功实现商业化，但其实际机械性能仍远低于理论值。与此同时，对优质碳纤维的使用需求不断增长。因此，人们进行了许多研究来提高碳纤维的机械性能。在各种方法中，设计具有发达微观结构和形态的高强度前驱体纤维可能是实现卓越性能的最有效策略。在这篇综述中，我们深入研究了为制备高强度前驱体纤维而在材料、加工和添加剂调控方面所做的努力。我们的工作表明，材料和工艺设计是提高碳纤维机械性能的有效途径。
