Effect of Polymer Sandwich Materials on Tensile-shear Strength of Laminated Steel Sheet

研究了高聚物夹层材料对层压减振复合钢板的拉伸剪切强度的影响 ,结果指出 ,高聚物夹层材料较厚时 ,层压减振复合钢板的拉伸剪切变形规律与高聚物夹层材料的一致 ;高聚物夹层厚度较小时 ,复合钢板的拉伸剪切强度较高。与酚醛树脂氯丁橡胶相比 。

The effects of polymer sandwich materials on the tensile-shear strength of laminated steel sheet were studied. It is shown that laws of tensile-shear deformation of laminated steel sheet are in good accordance with those of polymer sandwich materials when the thickness of polymer sandwich materials is greater, but the tensile-shear strength of laminated steel sheet is higher when the thickness of polymer sandwich materials is little. The laminated steel sheet using polyurethane as sandwich possesses higher tensile-shear strength in comparison with that using phenolic resin-chloroprene rubber.
