80年代以来,不连续相,尤其是颗粒增强铝基复合材料制备技术取得重大进展,同时材料本身具有优良的力学性能和低的制造成本,在汽车工业中显示出了巨大的应用潜力。一些颗粒增强铝基复合材料汽车零件,如刹车盘、驱动杆等的应用试验研究已趋成熟。但是这种材料的广泛应用还存在着障碍,许多工作需要进一步开展。 Since the 1980s, significant progress has been made in the preparation of discontinuous phases, especially particulate-reinforced aluminum matrix composites. Meanwhile, the material itself has excellent mechanical properties and low manufacturing costs, and has shown great potential in the automotive industry. Some particle-reinforced aluminum-based composite automotive parts, such as brake discs, drive rods and other application test research has matured. However, there are still obstacles to the widespread application of such materials and much needs to be done further.
