Experimental Evaluation of Damping of Fiber-Reinforced Composites
Anisotropic behavior of damping in fiber-reinforced composites is well established. An attempt is made to measure all the six loss factors for glass fiber-reinforced epoxy (three in normal and three in shear) experimentally using free decay method. Different types of specimen such as beam, tubular and cuboidal in shape made from glass fiber-reinforced epoxy are tested under different loading conditions. The six loss factors (η 11 , η 22 , η 33 , η 12 , η 13 and η 23 ) so determined are compared with the analytical results.
