Metal matrix composites (MMCs) are materials made by combining a metal with another material, often a ceramic or another metal. This combination enhances the properties of the metal, such as strength, stiffness, and resistance to wear and corrosion. MMCs are used in various applications, including aerospace, automotive, and sports equipment, where high performance is essential. The process of creating MMCs typically involves mixing the metal with the reinforcing material and then forming it into the desired shape. Common metals used in MMCs include aluminum and magnesium, while silicon carbide and carbon fibers are popular reinforcement choices. These composites offer improved performance compared to traditional metals alone.
