Carbon Fiber Reinforced Metal Matrix Composite
Carbon Fiber Reinforced Metal Matrix Composite (MMC) is a high-performance material that combines the properties of both metals and composites. It contains metal particles suspended in a matrix of carbon fibers. This composite provides more strength and stiffness than traditional metals, while also offering a better combination of physical and mechanical properties.
MMC has gained wide acceptance in various industries due to its superior properties and range of applications. It has been used extensively in the aerospace industry because of its high fatigue and corrosion resistance, as well as its ability to withstand high temperatures. MMCs have also been utilized in the automotive industry for high-performance components, and in medical and sports equipment.
The metal component of the composite is usually a steel, aluminum or titanium. The metal component provides the composite with strength and stiffness and also contains certain properties depending on the metal type chosen. The matrix component is composed of carbon fibers, which provide the composite with properties such as high-temperature resistance and vibration damping. The most common types of fiber used are E-glass, S-glass, and carbon fiber.
The fabrication of Carbon Fiber Reinforced Metal Matrix Composites is an intricate process and requires careful control over the variables involved. The most important steps in the manufacturing process are mixing and blending of the components, pressing and sintering, and finally forming and curing.
Mixing and Blending: The materials for MMC must be mixed and blended together in order to create the desired composite. The mix composition is dependent on the particular application, and different ratios of metal to carbon fibers can be used to optimize the properties of the composite.
Pressing & Sintering: The mixed components are pressed into desired shape and size under pressure, which is then heated to fuse and strengthen the bond between the metal and fibers. The composite is then cooled and sintered to create the desired structure.
Forming and Curing: The composite is then formed and cured, which is the final step in the manufacturing process. This process helps to further strengthen the bond between the metal and fibers and helps increase the strength and stiffness of the composite.
Carbon Fiber Reinforced Metal Matrix Composites have many features that make them attractive for use in a variety of industries. They are lightweight and strong, resistant to fatigue and corrosion, capable of dampening vibrations, and can withstand high temperatures and pressures. In addition, MMCs offer a wide range of design possibilities and can be tailored for specific applications. However, these composites can be expensive to produce and are not always suitable for large-scale manufacturing.
