| Summary: | In this paper, I have built a composite sample made from glass fiber as reinforcement and Aropol as
matrix. For this sample, I have used an experimental procedure to determine the damping properties and the
frequency of the first eigenmode. The experimental process is characterized by clamping the bar at one end and
leaving it free at the other. At the free end, I have placed an accelerometer to record the bar free vibrations. I
have applied an initial force, then I have removed the force and left the sample to vibrate without any other
restrictions. From these vibrations I have determined the damping factor and the eigenfrequency. |
