Using the provisions of the kinetic (thermofluctuation) theory of fracture of solids (Zhurkov theory) and the results of mechanical measurements it is shown that for samples of untwisted ultrahigh- molecular-weight polyethylene fiber made under identical conditions, but having scatter (variation) of mechanical properties, the strength values and other parameters resulting from the destructive process are in direct proportional dependence on the breaking elongation. The less the breaking elongation of the samples, the lower their strength. At the same breaking elongation, the strength tends to increase in proportion to the decrease in linear density of the samples.
