Vibration Behavior of Composite Materials Produced by Waste Metal Recycling

Abstract

In this study, waste metal chips were transformed into metal matrix composites by isostatic hot pressing and the vibrational behavior of these composite materials was investigated. Bronze chips (CuSn10) was used as a matrix component and spheroidal cast iron (GGG40) chips were used as reinforcement component. The metal matrix composites are produced with different GGG40 contents as 40%-30%-20% and 10%. Metal chips were pressed at pressure of 170 MPa and a temperature of 450 °C during production. The results of natural frequency and modal stiffness were evaluated on the basis of mixture ratios by applying the impact hammer test to the metal matrix composite materials produced.
