describes a new test to study the fiber-matrix interface in unidirectional composites by dynamic shear testing along the fiber axis. this method, based on three scans with increased dynamic displacement amplitude, enables the recovery of mechanical properties and appearance of damage in the material to be studied for carbon fiber-epoxy unidirectional composite materials, it is possible to distinguish two ranges in the amplitude of dynamic displacement' a first for which a recovery for g' and tan delta is observed and a second for which permanent damage appears. the influences of fiber surface treatments such as oxidation and/or sizing on dynamic behavior are clearly displayed by this test
