Abstract

A method for testing internal differences in reinforced flexible composites including placing a flexible composite on a rigid support structure, tapping the composite with a tapper of predetermined mass, determining a value representative of the impact duration of the tap and/or computing a value representative of the local stiffness of the composite. The composite may be a power transmission belt or portion thereof with tensile cord reinforcement. The method is useful for comparing the degree of penetration of elastomer into the tensile cord, for example in a cast polyurethane toothed belt.
