全球超过50％的金属基复合材料用于汽车工业的角度来看，这种材料的应用重

More than 50% of the metal matrix composite material for the view angle of the automotive industry, the application of such material will focus on the car (Vellingiri, 2018). Square large automotive parts made of composite material. Their specific cost and quality become the main reason for the application of these materials. Aluminum composite material having a commonly used to manufacture an engine piston, cylinder bore, the connecting rod, the vehicle braking system parts. Having a metal matrix composite material for the engine cylinders, pistons, disc and drum brakes and other components of the vehicle. In addition to using magnesium components, such as instrument panel, bonnet, and the transmission housing or the like of the steering column assembly outside the aluminum engine block, suspension components, body panels and the frame members are also more common (Vellingiri, 2018 ). Or alternatively a combination of these to work through the use of advanced micro- and nano-metal matrix composite materials can not only reduce the quality and reliability can be improved and efficiency.

More than 50% of the world's metal-based composites are used in the automotive industry, and the focus of this material will be on the automotive industry (Vellingiri, 2018). A large number of square car parts made of composite materials. Their cost-to-quality ratio is the main reason for the application of these materials. Composites with aluminum-based materials are commonly used to manufacture engine pistons, cylinder barrels, connecting rods, parts of vehicle braking systems, etc. Composites with metal substrates are used in engine cylinders, pistons, disc and drum brakes, as well as other components of the car. In addition to the use of magnesium in components such as instrument panels, valve covers, transmission housings and steering column components, aluminum engine blocks, suspension components, body panels and frame components are also becoming more common (Vellingiri, 2018). Combining or replacing these tasks by using advanced metal-based microns and nanocomposites not only reduces quality, but also improves reliability and efficiency.

Composite materials with aluminum base are usually used to manufacture engine piston, cylinder barrel, connecting rod, parts of vehicle brake system, etc. Composite materials with metal matrix are used for engine cylinder, piston, disc and drum brake and other components of automobile. In addition to the use of magnesium in components such as the instrument panel, bonnet, transmission housing and steering column assembly, aluminum engine block, suspension assembly, body panel and frame components are becoming more common (vellingiri, 2018). By using advanced metal matrix micro and nano composite materials to combine or replace these works, not only the quality can be reduced, but also the reliability and efficiency can be improved.
