【摘要】：简要总结了层状复合材料界面结合强度的非传统评价方法。非传统界面结合强度评价方法包括:波振法(激光层裂法、应力波法、超声波法、电磁波法)、划痕法(激光划痕法)、辅助分析法(X射线衍射法、有限元法、解析法)和其他方法(电阻法)。波振法是将载荷以冲击波的形式施加在界面位置处,实现复层和基体分离。划痕法是将高能激光作用于复层,分离界面,实现界面结合强度的测量。电阻法通过建立界面电阻和界面强度之间的关系,评价界面结合强度。与传统界面评价方法对比,非传统评价方法有特殊优点:对材料的破坏程度小,有效抑制材料的弹塑性变形,测得界面强度接近界面本征强度。但非传统法也仍存在一些亟待解决的问题,随着新材料的不断出现,需要不断改进现有测试方法,使界面结合强度评价方法向着简单易行、无损、自动化的方向发展。
[Abstract]:The non-traditional evaluation methods of interfacial bonding strength of laminated composites are summarized briefly. Non-traditional methods for evaluating the strength of interface bonding include: wave vibration method (laser spallation method, stress wave method, ultrasonic method, electromagnetic wave method, scratch method (laser scratch method), auxiliary analysis method, X-ray diffraction method, finite element method, etc. Analytical method and other methods (resistance method). The method of wave vibration is to apply the load in the form of shock wave at the interface to separate the layers from the matrix. The scratch method is used to measure the bonding strength of the interface by using high energy laser to separate the interface. The resistance method evaluates the interface bonding strength by establishing the relationship between the interface resistance and the interface strength. Compared with the traditional interface evaluation method, the unconventional evaluation method has special advantages: the damage degree of the material is small, the elastic-plastic deformation of the material is effectively suppressed, and the interface strength is close to the intrinsic strength of the interface. However, there are still some problems to be solved in non-traditional methods. With the emergence of new materials, it is necessary to continuously improve the existing testing methods to make the evaluation methods of interface bonding strength simple, non-destructive and automatic.
