界面是制约复合材料性能的关键性因素,同时界面效应的存在也为复合材料的设计与改进提供了一条重要的途径[1].因此,界面设计与界面控制工程已成为当前复合材料领域极为活跃的前沿课题,而该项工作的开展则以准确的界面性能表征为前提[2].然而,针对颇具应用前景的非连续增强金属 The interface is a key factor that restricts the performance of composite materials, and the existence of interface effects also provides an important approach for the design and improvement of composite materials [1]. Therefore, interface design and interface control engineering have become extremely active in the field of composite materials Of the forefront of the subject, and the work carried out with an accurate interface performance characterization as a precondition [2] However, for the quite promising application of discontinuous reinforcing metal
