Abstract
The aim of the study is to create a methodology for calculating the equal strength of structural elements of composite reinforcement in tension and transverse shear and to develop recommendations for conducting tests to determine the mechanical properties in tension. In theoretical studies, design schemes were compiled and a comparative structural and mechanical analysis of composite reinforcement was performed according to the criteria for strength at break of the rod, as well as shear strength
of its polymer shell. It is shown that the main contribution during the tests is made by the transverse shear strength of the polymer shell in special couplings for gripping the samples, as well as the alignment of the samples and couplings during the tests. Recommendations are given on calculating the minimum required coupling length and on ensuring alignment of samples and couplings.
