摘要/Abstract

摘要：

通过搭接剪切试验,获得了复合钢板中黏结树脂层的切向力学性能数据，切向黏结强度为10.64 MPa；针对T剥离试验应用于本研究对象的缺点，设计了一种制作法向拉伸试样的夹具,并利用该夹具通过单向拉伸获得了树脂层法向力学性能数据，法向黏结强度为13.04 MPa.最后对该复合钢板进行V形折弯试验，通过分析回弹角随时间的变化规律，认为树脂层黏性不明显.这些工作为后续复合钢板折弯回弹成形影响因素数值模拟的参数化分析建模提供了依据.

关键词: 复合钢板, 黏结性能, 搭接剪切试验, 法向拉伸试验, 黏性

Abstract:

A lap-shear test was conducted to obtain the shear property of the polymer layer in a laminated steel sheet, and shear strength was acquired as 10.64 MPa. A clamp mould was designed to make samples for normal tensile tests so as to get the normal property data of the polymer layer because of the engendered defects of T-peel test applied, and the tensile strength was obtained as 13.04 MPa. The viscosity of the polymer layer was investigated by examining the variation with time of bent angles of laminated steel sheet samples acquired from the V-bending experiment. It was shown that the viscosity of the polymer layer was not significant. The experiment results will be conducive to future numerical parametric analysis of influencing factors on bending and springback of the laminated steel sheet.
