为了提高汽车的加速性、操纵性、舒适性和降低油耗,实现汽车轻量化,复合材料在汽车中的应用正在增加。其中FRM是把铝或镁等轻合金,用纤维增强以后使强度、刚性、耐磨性、低热膨胀性等性能得到提高,研究将其应用于汽车发动机零件。目前日本丰田汽车公司的柴油机耐磨活塞环使用了Al_2O_3-SiC纤维,在热负荷大的活塞顶部的周围填充了上述纤维后,环槽的耐磨性、抗烧伤性提高,可实现发动机的高输出功率。本田公司采用了填充不锈钢纤维的连杆,
In order to improve the car’s acceleration, maneuverability, comfort and reduce fuel consumption, to achieve lightweight car, composite materials in the automotive applications are increasing. Among them, FRM is made of light alloy such as aluminum or magnesium. After being reinforced with fiber, the properties such as strength, rigidity, abrasion resistance and low thermal expansibility are improved. The research is applied to automobile engine parts. At present, Japan’s Toyota Motor Corporation wear-resistant piston rings wear Al 2 O 3-SiC fibers, the top of the heat load in the piston around the top filled with the above fibers, the ring groove wear resistance, anti-burnability can be achieved high engine Output Power. Honda employs a connecting rod filled with stainless steel fibers,
