技术领域
本发明涉及一种碳化硅颗粒增强铝基复合材料的制备方法。
背景技术
随着现代科学技术的迅速发展，除了要求材料具有良好的综合性能，还要求某些特殊性能。单一金属、陶瓷等工程材料难以满足这些要求，而金属基复合材料便随之发展起来，满足了特定的需求。其中碳化硅颗粒增强铝基复合材料作为金属基复合材料的一种，具有低密度、低膨胀、高导热、高弹性模量、高硬度、高刚度并且具有各向同性等优异性能。随着我国科学技术的不断进步，碳化硅颗粒增强铝基复合材料将在高速列车、航空航天、军工等高端装备制造领域有着很大的需求。虽然碳化硅颗粒增强铝基复合材料具有如此多的优越性能和广泛的应用，但是制备碳化硅颗粒增强铝基复合材料的工艺仍然不是很成熟，在国内还没有一个比较成本低、成熟、稳定的制备工艺。所以很有必要对碳化硅颗粒增强铝基复合材料进行更多、更深入的研究，以追赶国外先进的技术水平。
