Composite Material Damping Using Impulse Technique,

Abstract

An experimental technique known as the impulse technique is presented for measuring the internal damping of composite materials. In order to gain confidence on the experimental data measured from this technique some improvements have been made. The improvements involve the following: (a) to replace a contact probe a non-contact probe; (b) to use an amplifier to reduce the noise level; (c) to use a spring to control the magnitude, location and dwelling time of the applied force; and (d) to use zooming technique to obtain more accurate data.
