Purpose: of this thesis is to present the exemplary results of strength tests of sandwich composite materials consisted of the laminate plate and the metal sheet plate. Design/methodology/approach: The strength tests were carried out in the laboratory stand by means of the electric resistance wire strain gauge. The laboratory stand was specially designed for the purpose of testing composite materials. Findings: The results are presented in the form of graphs. In graphs the maximal and minimal strains in the time function are presented. Research limitations/implications: The tests were carried out for different configurations of the samples. The specimens were prepared as the samples with the external steel plate or with the steel plate arranged among the laminate layers. Practical implications: The experimental tests are still necessary in analysis of the composite materials. The real parameters of the samples should be determined in an experimental way. However, the numerical computer simulation of the composite materials is possible e.g. in Unigraphics software, but modelled in the computer environment composites have very often some errors and results of simulation is not proper. Originality/value: The sandwich composite materials were tested in the laboratory stand by means of extensometers. The results could be used in designing of mechanical parts and mechanisms made of the laminate connection in the steel plate by means of screws. The fundamental mechanical properties of such a type materials were derived.
