Influence of stress concentration of particles of the filement on the structure and strength of the interfacial layer in polymer composites

It is shown that the calculation of the strength of the interfacial layer $\sigma_a$ of particulate-filled polymer composites within the framework of the cluster model of the structure of the amorphous state of polymers correctly gives not only the trend of change $\sigma_a$, but also the quantitative values of this parameter.
