TENSILE-SHEAR CHARACTERISTICS OF DAMPING LAMINATED COMPOSITE STEEL SHEET

  • The tensile-shear characteristics of the damping laminated composite steel sheet,which uses phenolic resin-chloroprene rubber polymer for sandwich,have been studied using four strain rates of 1.67×10-2,1.67×10-3,1.67×10-3 and 1.67×10-5s-1,in the range of testing temperature from 20℃ to 150℃.The results show that the damping laminated composite steel sheet is of high tensile-shear strength,and its destruction morphology exhibits the features of mixed destruction of polymer being torn and interface destruction,with high strain rate and low temperature.At the temperature of about 80℃,the tensile-shear strength is of the minimum value,and the destruction of polymer possesses the characteristic of slip deformation.In the range of testing temperature from 80℃ to 150℃,the tensile-shear strength increases with the rising of testing temperature;this is due to the cross linking reaction taking place in the polymer sandwich.
