Reinforced Matrix Syntactic Foams Filled with Ceramic Hollow Spheres

Abstract Metal matrix syntactic foams are cellular materials in which the is metal and within that non-metallic cells formed by filler material. These have low density, besides that, they high compressive strength energy absorption. The main goal was to improve these properties reinforcing with ceramic grains. During experiment, molten A356 aluminium (7Si-0,3Mg) infiltrated between mixture of reinforcement specimens were produced low-pressure infiltration. Different used: aluminium-oxide three different grain sizes colour designations one type silicon carbide. After heat-treatment, standardised compression tests executed on specimens. results compared non-reinforced samples.
