中文摘要:
      目的 探究纳米Fe3O4增强硅橡胶与铁氧体的界面黏结特性。方法 分别开展准静态拉伸试验、界面法向和切向黏结强度试验。采用超弹性理论,分析纳米Fe3O4增强硅橡胶材料的拉伸行为,采用双线性和指数内聚力模型,分析纳米Fe3O4增强与铁氧体的界面破坏行为。结果 通过拉伸试验获得了不同纳米Fe3O4含量的硅橡胶的工程应力应变曲线及两参数Mooney-Rivlin模型,小变形范围的模型误差在1%以内,大变形范围的最大误差为3.8%。通过界面强度试验,获得了不同纳米Fe3O4含量的硅橡胶和铁氧体界面的法向和切向力-位移曲线、黏结强度和界面断裂能,得到了界面法向和切向黏结强度内聚力模型参数。结论 随着纳米Fe3O4含量增加,硅橡胶的拉伸强度增加,界面法向黏结强度和断裂能增大,而切向黏结强度和断裂能变化不显著。双线性内聚力模型更适合作为纳米Fe3O4增强硅橡胶与铁氧体的界面黏结强度表征模型,界面法向和切向黏结强度变化规律与实测值的吻合程度更高。
英文摘要:
      The work aims to investigate the interfacial bonding characteristics of nano-Fe3O4 reinforced silicone rubber with ferrite. Quasi-static tensile tests, interfacial normal and tangential bonding strength tests were conducted. The hyperelasticity theory was applied to analyze the tensile behavior of nano-Fe3O4 reinforced silicone rubber, and bilinear and exponential cohesive models were utilized to analyze the interfacial damage behavior of nano-Fe3O4 reinforced with ferrite. The engineering stress-strain curves of silicone rubber reinforced by nano-Fe3O4 particles with different content were obtained by tensile tests, and two-parameter Mooney-Rivlin model was gotten as well. The error of the model in a small deformation range was less than 1%, and that in a large deformation range was 3.8%. Through interfacial strength tests, the normal and tangential force-displacement curves, the interfacial bonding strength and interfacial fracture energy, and the parameters of the interfacial cohesive model for the interface of silicone rubbers with different nano-Fe3O4 contents with ferrite were obtained. The experiments show that the tensile strength of silicone rubber and the interfacial normal bonding strength and fracture energy increase with nano-Fe3O4 content, while the tangential bonding strength and fracture energy do not depend significantly on the content. The bilinear cohesion model is more suitable for the characterization of the interfacial bonding strength of nano-Fe3O4 reinforced silicone rubber and ferrite, and the interfacial normal and tangential bond models are in better agreement with the measured values.
