A STUDY REGARDING THE DAMPING CAPACITY OF COMPOSITE BARS REINFORCED WITH FIBER GLASS AND THE MATRIX MADE WITH AMBRESIT

Abstract

In this paper, we have built some composite bars with the reinforcement made by fiber glass which is randomly disposed and the matrix made by ambresit. Then, in order to study the samples free vibrations, we have clamped the bars at one end and we left the other free. At about 5 mm from the free end, we have placed an accelerometer and an initial deformation to the bar. Then, by removing the initial deformation we left the bar to freely vibrate. From these vibrations we have determined the bars damping factor and eigenfrequency.
