Hybrid Preform for Metal Matrix Composites: Processing and Characterization

Abstract:

Article Preview

Metal matrix composites (MMCs) have been used for aviation, automobile and nuclear application due to their highlight properties such as superior strength, high specific stiffness, wear, and creep resistance at elevated temperature. For developing MMCs by liquid infiltration, preform will be required. In this research paper, developed a hybrid fiber preform and investigated their microstructure properties. Graphite nano fiber (GNF) and Alumina fiber were used for fabrication of the preform. The main objective of developing a preform is i) attainment of uniform distribution of reinforcement ii) minimization of mechanical and chemical damage. Since, it is extremely difficult to disperse nano-size fibers uniformly into the preform. An attempt has been made for hybrid preform with alumina micro-fiber and graphite nano fiber. Microscopic investigations revealed good disperse of the nanofibers in the preform.
