为了加速机器制造、冶金、电力和其他技术领域的科技进展,必须研制种种新型材料及其相应的工艺方法。最近10～15年,为获得加强纤维,在金相学和理化过程的研究方面所取得的成就从根本上导致了新型复合材料的创制。这样,在提高机器、仪表、装备和 In order to accelerate technological progress in the fields of machine building, metallurgy, electric power and other technologies, it is necessary to develop various new materials and their corresponding process methods. In the recent 10 to 15 years, the achievements made in the study of metallography and physical and chemical processes have fundamentally led to the creation of new composite materials in order to obtain reinforced fibers. In this way, in improving the machinery, instruments, equipment and
