炭素纤维是近30多年来发展起来的新型材料。它具有高强度、高模量、比重轻、耐高温、能导电等多种优良性能。我国在70年代即已有了用聚丙烯睛纤维为原料的炭纤维生产,但由于成本高、产量低,其发展受到很大的限制,仅在航天和国防工业上有少量的应用。而
Carbon fiber is a new material developed in recent 30 years. It has high strength, high modulus, light weight, high temperature, can conduct a variety of excellent performance. In the 1970s, China already had carbon fiber production using polypropylene fiber as its raw material. However, its development has been greatly restricted due to its high cost and low output, with only a few applications in aerospace and defense industries. and
