  • Metal-Polymer Research Institute of Bneloressian Academy of Sciences is taking an active part in research and developments in field of polymer materials and composites. Many of these materials are devoted to use as a construction materials for machine parts, protective and decorative coatings on metals, films preventing corrosion in packaging of electronic, machinery and other components. This list can be continued by mentioning polymer capsulation coating for fertilizers, polymer filters produced by extruding and transfer of melted fibers etc.

  • The present study describes the wear and mechanical behaviour of carbide composites in cyclic loading applications (blanking of sheet metal). Adhesive wear as well as fatigue endurance were tested, complemented by XRD studies. It was found that the blanking performance of a carbide composite is controlled by its resistance to adhesion wear and fatigue sensitivity. XRD studies revealed that fatigue damage is preceded by plastic strain in both phases of the composites

  • In this study, stress-displacement analytic solutions are obtained by a shear lag modeling method constructed for the spliced joint area with a splicing gap in the fiber metal laminate (FML). This gap can be empty or be filled with an adhesive material of elastic modulus $E_a$. Two splicing types are considered for spliced shear models, one for spliced in the center metal layer, the other for spliced in the outer metal layer. It is shown that from the viewpoint of the load transfer efficiency and the avoidability of disbond generation due to the shear and axial stresses at the interface between metal layer and composite layer of the gap-front in the spliced area, the center spliced type (k=2) is much preferable to the outer spliced type (k=1).
