摘要
用Instron5565万能强力机对不同金属/PET复合材料在不同温度、不同金属厚度、不同速度下进行力学性能的测试.实验结果发现,温度对金属/PET复合材料的力学性能影响最大.当超过PET玻璃化温度之后金属层对复合材料的初始模量影响显著,并且厚度在6.7μm时,对PET的初始模量贡献最大.拉伸速度增加使材料初始模量和拉伸强度增大但伸长率减小.
The mechanical properties of the metal/PET composites with different coating metal films and different thicknesses of the metal films as well as those of the metal/PET composites under different testing temperatures and different speeds of tensile were measured by Instron 5565 universal testing machine. The testing results indicate that the testing temperature has the greatest influence on the mechanical properties of the metal/PET composite. When the temperature exceeded the glass-transition temperature of PET, the coating metal film has a marked influence on the initial modulus of the composite. Furthermore, the initial modulus of the metal/PET composite with a film thickness of 6.7μm shows the maximum value. In addition, the initial modulus and the tensile strength of the metal/PET composite increased with the increasing speed of tensile. However, the tensile elongation of the metal/PET composite decreased with the increasing speed of tensile.
