In the previous papers [11-13] a significant influence of material layer elastic modules on the behaviour of multilayer structures was determined.

It has been obtained that increasing the ratios of the layer material elastic modules [[xi].sub.2,1], the relative radial stresses of the inner layer of PC increase from zero to the maximum value, but in the outside layer they decrease (curves 1, 3 Fig.

Measuring time intervals between the echo signals reflected from the specimen face and bottom enables us to find local values of sonic velocities and elastic modules of the material under investigation.

Most of these specimen values of sonic velocities and elastic modules possess minimal differences with the corresponding values of pure epoxy.

Also it is seen from the results that the elastic modulus of the second infill interface has a higher influence as compared to the elastic modulus of the first infill interface but the influence of both the elastic modules is lower that the yield strength of the infill material.
