An Investigation on the Damping Characteristic of Polymer Concrete With Polyester Resin

Authors: Sezan ORAK, Şerafettin KARADEMİR

Abstract: In this study, the usability of polymer concrete in the manuacture of machine tool beds was investigated with respect to its damping characteristic. Samples which consisted of the same polyester resin ratio and different quartz material ratios were used in order to investigate changes in the damping characteristic with structure. Damping experiments were carried out using polymer concrete and cast iron samples. Critical damping ratios were calculated with the free vibration method. It was observed that the critical damping ratio of polymer concrete was approximately 4-7 times higher than that of cast iron.
