Conclusions

The strength of high-modulus yarns is connected by a direct linear dependence with the rate of sound propagation and by an inverse linear dependence with the damping coefficient of ultrasonic waves.

Thermal aging leads to a monotonic decrease in yarn strength and rate of sonic wave propagation, and to a linear increase in the damping coefficient, a change in molecular orientation always causing a more marked change in the damping coefficient than in the velocity of sound.

The linear dependence between c (σ) and α (σ) is broken up in the case of heat-drawn yarns; this is connected with formation of defects in the material.
