METAL-MATRIX COMPOSITES phd thesis on metal matrix composites (MMCs) are a class of materials with poten- tial for a wide variety of structural and thermal management applications. Some MMC properties cannot be measured as they would be for monolithic metals. Nanoparticles directly inside the polymer matrix is more advantageous for the production of polymer-nanoparticle composites. Gof the composites is improvedsubstantially. The applications of metal matrix composites (MMCs) are being increasing day by day in a number of industries, especially in aerospace and automobile industries. The combination of light weight, environmen- tal resistance, and useful mechanical proper- ties has made aluminum alloys very popular; these properties also make aluminum well suited for use as a matrix metal 1.
