Polymer composites reinforced by knitted fabric are materials with high potential in aerospace and machine building industries. In the same time such materials are mechanically non-linear with a high dynamic energy absorption possibility. Precise mechanical properties prediction has the great importance for such material use in novel structures. Three different approaches were executed and results are presented in: Part 1- numerical (FEM, using Solid Works software) structural modeling based on reinforcement and matrix mechanical and geometrical properties (were measured experimentally) and direct experimental mechanical properties measurement approach; Part 2-inverse method approach for mechanical properties appreciation, based on vibrations modal analysis; with the goal to obtain and predict welf knitted fabric reinforced multilayered composite plate mechanical behavior. All three approaches results were compared and comparison results were discussed.
