Conclusions

The effect of molecular orientation and of tension in the specimen on the propagation velocity and absorption coefficient of longitudinal ultrasonic waves has been investigated with the aid of an acoustical method.

The dependences found for the rate of propagation and the absorption coefficient of ultrasound have made it possible to analyze the mechanism of sound passage through a specimen as the fibre is straightened out.

A relationship has been found between the change in rate of propagation and the damping coefficient of ultrasound in the process of molecular orientation.
