This document describes a pulse propagation method for determining the storage component of the complex tensile modulus E\' of polymers at discrete frequencies typically in the range 3kHz to 10kHz. The method is suitable for measuring materials with storage moduli in the range 0,01GPa to 200GPa and with loss factors below 0,1 at around 10kHz. With materials having a higher loss, significant errors in velocity measurement are introduced through decay of amplitude.

The method allows measurements to be made on thin films or fine fibres and long specimens, typically tapes of 300mm×5mm×0,1mm or fibres of 300mm×0,1mm (diameter).

This method may not be suitable for cellular plastics, composite plastics and multilayer products.
