From the results of experiments was established the optimum thickness of the investigated composite material specimen for maximum to rumple resistance. It is shown that the layers of the composite scheme of laying 0? reduce tensile strength at rumple 10 ... 20%. The method of measuring surface topography composite using electronic speckle interferometry (ESI), which can detect hidden defects in the vicinity technological holes and measure their size for a small load. Calculation-experimental method for determining the mechanical stiffness of connection "composite-metal" with the using DIC method imaging surface samples during tests on rumple.
