Determination of the Composition and Density of Polymer Composite Materials in Details and Constructions by Nondestructive Methods

摘要

The physical basis of the method of diagnostics of polymer composite materials for determination of their composition and density, as well as information-bearing parameters of diagnostics, are considered. The correlation between the content of the filler and density of the material and the velocity of propagation of the impulse of ultrasonic vibrations is studied. It is shown that the composition and density of the material can be determined to a high precision by the control procedure described in the article only at low porosity.
