The most pressing problem of improving the reliability of the air-ship equipment is the problem of improving its quality as the main indicator for reliability assessing of high-duty assemblies. The control of the components and equipment assemblies reliability has gained considerable importance these days. It depends not only on the material properties but also on its latent structural inhomogeneities that lead to deviation of material physical-mechanical characteristics from the nominal values. For diagnostics of polymer composites (PC) physical and mechanical properties diagnostics methods using acoustic, heat, electrical and other non-destructive testing methods are used but in other quality. Ultrasonic methods are the main of the named above (by the number of problems solved). These methods do not require bulky hardware and can be applied not only in laboratories but also in workshops and even in the field. As a result of works carried out in VIAM the control technologies have been developed launched methodological materials have been launched, technological recommendations and manufacturing instructions on porosity determination, density, fibre and matrix content in CFRP, have been developed as well as strength upon interlaminar shear and compression of unidirectional CFRPs, matrix polymerization degree at different stages of integral constructions production have been worked out.
