An Experimental Study Regarding the Vibratory Behaviour for Some Textile Composites

摘要

The paper presents the results of our research in the elaboration and characterization of composites type epoxy - textile fiber and vibration behaviour. These were made by pressing, and the textile fibers we tested were cotton, flax, hemp and wool. Starting from the dynamic response of composite beam with damping (which is in free vibration), there is established a way to determine the damping factor. There has been experimentally determined the damping factors for some samples: sample 1 - built from cotton; sample 2 - built from hemp; sample 3 - built from flax; sample 4 - built from whool.
