近20年来非金属复合材料被称为未来的航空航天材料。如今,复合材料的广泛应用并非在民用飞机的表面控制和承载结构方面、军用飞机原有结构的强度、刚度、隐身超越控制方面取得明显进展,而是在金属与非金属技术结合形成一种新材料方面有所突破。许多种非金属材料都能强化铝和其它金属,提高它们的强度和刚度。铝的增强剂可以是弥散分布的微观粒子,也可以是贯穿整个基体结构长度的连续纤维。这种纤维能存在于基体金属中,或作为铝层之间的叠层。圣地亚哥公司的硬质铝(或称杜拉铝)基复合材料是由工业级铝和陶瓷粒子——氧化铝(Al_2O_3)或是碳化硅制成的低成本复合材料。一种特有的加工过程允许具有化学活性的熔 For nearly 20 years, non-metallic composites have been described as future aerospace materials. Today, the widespread use of composites is not about surface control and bearing structures for civil aircraft. The strength, stiffness, stealth and overrunning control of the original structure of military aircraft have made significant progress. Instead, the combination of metal and nonmetal technology has created a new Material breakthroughs. Many types of non-metallic materials reinforce aluminum and other metals to increase their strength and stiffness. Aluminum reinforcing agents can be dispersedly distributed microscopic particles, it can also be continuous throughout the length of the matrix structure of the fiber. Such fibers can be present in the base metal or as a laminate between aluminum layers. San Diego’s hard aluminum or duralumin-based composites are low-cost composites made of industrial-grade aluminum and ceramic particles-alumina (Al 2 O 3) or silicon carbide. A unique process allows chemically active melting
