摘要
碳纤维是一种力学性能优越的特种纤维,广泛应用于国防、航空航天、医用、工业、体育等众多领域。沥青基碳纤维可由沥青经萃取、缩聚、纺丝、氧化、碳化而制得。阐述了沥青基碳纤维的发展背景、制备原理及应用领域等。
Carbon fibers are considered to be high strength materials having great importance in variety of specialized applications,such as national defence,clinical use,aerospace,industry and sports.The pitch-based carbon fibers can be prepared from raw pitch which be treated by extraction,condensation,spinning,oxidation and canbonization.It has promising future due to ample raw materials and low cost.The background,preparation and application of pitch-based carbon fibers was introduced in the paper.
