In this study, carbon fiber and glass fiber composite materials with 0 ° tilt angle with holes in circular, square, and hexagonal profiles were assembled using resolvable connection methods. It was aimed to determine which profile structure was suitable for stress accumulation and load capacities in carbon fiber composite and glass fiber composite materials. Numerical and experimental studies have been carried out for this purpose. In experimental studies, samples of different profiles were subjected to tensile testing on the tensile tester after the connections were made. Numerical studies have used the ANSYS 14 finite element package program for the design of specimens of different profiles and for the application of tensile tests. By comparing the results of experimental and numerical studies, it was determined that the optimal profile structure is circular profile.
