It has been shown that elasticity modulus and yield stress proportionality for polymer composites can be special case only. In the general case enough large amount of both molecular and structural factors existed, which influenced additionally and enough strongly on yield stress value. The fractal models allow to determine limiting values of yield stress for considered polymer composites.
