A mechanical system consisting of a blade prestressed on a rotating disc is considered. Such system forms a tribometer developed in order to accurately determine the surface state of fibrous materials. The surface to be analyzed is fixed on the disc, and the blade, on which is fixed strain gages, is the sensor. Until now a Fourier analysis, performed on the friction‐induced vibration signal provided by the strain gages, allowed to deduct roughness–friction criteria. However, in addition to obscure the nonlinear part of the signal, Fourier analysis method requires acquisition of important data for a very long processing time. The present study was designed to assess the applicability of a nonlinear mathematical tool, recurrence plot and recurrence quantification analysis (RQA), in addressing the problem of fibrous surface analysis and overcome the drawbacks of the Fourier analysis. The results show that these tools are able to replace the Fourier analysis and make available additional parameters, owing to RQA, that enhance the understanding of physical phenomena of our particular problem.
