摘　　要：由于中间相沥青基碳纤维在模量和导热上具有性能优势,使其在航空航天等尖端领域具有不可替代性。目前,我国相关产业仍受限于纺丝用中间相沥青的制备,未能形成中间相沥青基碳纤维的成套生产技术。本文总结了纺丝用中间相沥青的制备工艺和关键影响因素,展望了中间相沥青的发展前景。Due to the advantages of high modulus and thermal conductivity,mesophase pitch-based carbon fibers are irreplaceable in cutting-edge fields such as aerospace.At present,the development of related industries in China is still limited by the preparation of spinnable mesophase pitch,thus incapable to form a complete set of production technologies for mesophase pitch-based carbon fibers.This paper summarizes the preparation methods and key influencing factors for spinnable mesophase pitch,and the development prospect of mesophase pitch is also prospected.
