摘　　要：本文选用１．６７×１０￣（－２）、１．６７×１０^（－３）、１．６７×１０￣（－４）、１．６７×１０￣（－５）ｓ￣（－１）四种形变速率，在２０～１５０℃试验温度范围内研究了用酚醛树脂氯丁胶作夹层的层压减振复合钢板的拉伸剪切特性。结果指出，在较低温度和较高形变速率下，层压减振复合钢板具有较高的拉伸剪切强度，其破坏形态呈高聚物撕裂和界面破坏的混合破坏特征；在８０℃附近，拉伸剪切强度最低，其破坏形态为具有滑移特征的高聚物内聚破坏；在８０～１５０℃温度范围内，随温度升高，拉伸剪切强度增加，这是由于高聚物夹层材料中的氯丁橡胶发生了交联反应的缘故。The tensile-shear characteristics of the damping laminated composite steelsheet,which uses phenolic resin-chloroprene rubber polymer for sandwich,have beenstudied using four strain rates of 1.67×10￣(-2),1.67×10￣(-3),1. 67×10￣(-4) and 1.67×10￣(-5)s￣(-1),inthe range of testing temperature from 20 ℃ to 150 C。 The results show that the dampinglaminated composite steel sheet is of high tensile-shear strength,and its destructionmorphology exhibits the features of mixed destruction of polymer being torn and interfacedestruction, 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 possessesthe characteristic of slip deformation. In the range of testing temperature from 80 ℃ to150℃,the tensile-shear strength increases with the rising of testing temperature;this is dueto the cross linking reaction taking place in the polymer sandwich.
