Mechanical joining of composite and metal components is an increasing necessity in various engineering applications for improved efficiency and minimal structural weight. Mechanical joints such as bolted and adhesive joints have been widely implemented in aerospace, automotive and wind power applications. However, they possess some significant drawbacks such as stress concentrations, abrupt change of stiffness and brittleness of failure. To overcome these disadvantages a novel type of composite/metal joint with textile mesostructure was investigated in the present study, where carbon fiber and steel fiber yarns are gradually interwoven obtaining a functionally graded composite material. The present work presents results of numerical simulations performed in ANSYS FEM software and their comparison with experimental results of mechanical elastic properties of knitted and woven carbon/steel fiber composites. Results show good agreement between numerical predictions and experimental results.
