从汽车零件到宇航器材,应用复合材料和陶瓷材料代替传统的金属材料已经取得重大的效益。 例如,日本五十铃汽车公司正在制造Si_3N_4陶瓷汽缸衬套,用于小型柴油发动机。由于利用了陶瓷耐热特性和热绝缘特性,使之能够承受瞬时升温,据说“这种柴油发动机可以象汽油发动机一样快速启动”。 在复合材料的情况介绍中,尼瓦达工程技术公司注意到“有机填料复合材料的金属基复合材料应用更为广泛。他们已经认识到了金属基复合材料的这个缺点,并且在不断
Significant benefits have been achieved in replacing traditional metal materials from automotive parts to aerospace equipment, the use of composite materials and ceramic materials. For example, Isuzu Motors Corporation of Japan is manufacturing Si_3N_4 ceramic cylinder liners for small diesel engines. Thanks to the ceramic’s heat-resistant properties and thermal insulation properties that make it capable of withstanding transient heating, it is said that “this diesel engine can start up as fast as a gasoline engine.” In a presentation on composite materials, Nieida Da Engineering Company noted that "metal matrix composites with organic filler composites are more widely used, and they have come to recognize this shortcoming of metal matrix composites and are constantly
