Abstract: The paper deals with mechanical response of conventional homogeneous materials and short and long fiber composites that are excited by impact force. Such type of excitation is typical for dynamic effects in the machine tool performance. The maximum portion of generated vibrations should be damped. The material damping is one of factors improving the damping properties. The paper provides the results of measurements that analyze mainly the natural frequencies, character of Fast Furier Transformation spectrum focusing on damping time of conventional and nonconventional materials, carbon and glass fibers and their different material configuration.
