Abstract The article discusses compressive forces tests in composite-concrete pillars with the use of laboratory active experiment including the factors and properties of materials which have a significant impact on the test results and their repeatability. A polymer composite based on glass fiber reinforced resin with different fiber beam angles (20°, 55° and 85°) was used as a buffer/coat of the pole. Due to the problems with direct comparison of the obtained discrete measurement results for different angles of the fiber winding, a transition from the measured discrete signals to the continuous description was proposed. Using this approach, it was possible to include control systems, identification theory and finally metric spaces in the research methodology. The latter made it possible to determine the relations between compressive forces for the various examined poles and their coats, and further, to define the partial order in the space of the poles studied and their coverings. The obtained results indicated the wide possibilities of the proposed test methods for compressive forces in composite-concrete pillars and their glass-fiber reinforced coats.
