BRITTLE FRACTURE RESISTANCE AND DAMPING PROPERTIES OF A STEEL-RUBBER METAL-POLYMER COMPOSITE

The results of comparative tests for impact bending of 09G2S steel specimens and a cold-glued 3-layer “09G2S steel–1F-1-HFAA-С rubber” composite show that, unlike the base steel, the metal-polymer composite retains increased values of impact strength KCV at temperatures ranging from 20 to −60 °C. The high level of the brittle fracture resistance of the steel-rubber composite under dynamic loading conditions at low temperatures results from the development of the delamination toughening effect characteristic of layered materials. The 100-cycle alternating tests and processing of their results have made it possible to construct mechanical hysteresis loops for the steel base and the metal-polymer composite and to determine the main parameters governing the damping capacity of the materials (the values of the mechanical loss angle tangent and the components of the complex elastic modulus). The possibility of using the metal-polymer composite under study, which is highly resistant to brittle fracture at low climatic temperatures, in highly vibration-resistant structural components of transport systems is demonstrated.
