Purpose of the development: Intended for: 1. Providing obtain high accuracy over a wide temperature range of acoustic characteristics of the fibers: - speed of sound, - sound absorption coefficient. 2. Calculation of the visco-elastic properties of the fibers: - in particular the Young's modulus (real and imaginary part), - young's modulus of the second order. 3. Assessment of the quality of the composite fibers.

Recommended application field: - production of fibers, composite fibers, in particular optical, non-destructive quality control; - analysis of hair for cosmetic applications, analysis of the effect of detergents or chemicals on the human condition of the hair.

Technical characteristic: Equipment: 1. Emitter. 2. Sample. 3. Generator. 4. Receiver. 5. Power. 6. Oscilloscope. 7. Voltmeter. 8. Block. 9. Weights.

Advantages over analogues: The device allows you to: - to carry automatically in a wide temperature range to measure and analyze the results. Elaborate theory of ultrasonic vibrations in the composite fibers allows you to: - to analyze the quality of the form of acoustic inter- ferograms fibers.

The development stage readiness: tested in laboratory condition

Description of the development:
()
Visco-elastic properties of the fibers in the ultrasonic range are installed acoustically - an interferometric method. The principle of operation is to register the amplitude of ultrasonic oscillations on the distance between the transmitter and detector moving oscillations.
