Polymer and concrete matrix composites reinforced by knitted fabric were investigated. Such materials are mechanically non-linear with a high dynamic energy absorption possibility. Precise mechanical properties appreciation and prediction are important for materials use in novel structures. Three different approaches were executed - numerical (FEM, using Solid Works software) structural modeling based on reinforcement and matrix mechanical and geometrical properties (were measured experimentally), direct experimental mechanical properties measurements and inverse method approach for mechanical properties appreciation, based on vibrations modal analysis. All three approaches results (for polymer matrix composites) were compared and comparison results were discussed.
