Conclusions

In the case of yarn based on an aromatic polyamide, it has been shown that the strength distribution of the elementary filaments in the complex yarn can be equally well described by the normal distribution laws or by a Weibull distribution.

For the Weibull distribution, an analytical expression has been found which connects the strength variation coefficients of the complex yarn and of the elementary filaments.

A method is suggested for evaluating the deviation in behavior of real complex yarns from that of bundle model, which consists in estimating the critical length of an elementary filament in the complex yarn. The method permits using the indicated model in practice.
