U.S.-German Cooperative Research on In-Situ Studies of Micormechanisms of Delamination in Novel Laminated Composites with Nanoreinforeced Interfaces

PI和凯撒斯劳滕大学的Klaus Friedrich的这项合作的目标是研究具有纳米增强界面的新型层状化合物的分层微观机制。电纺产生的纳米纤维被用来抑制分层和微裂纹扩展。层间压裂将用最先进的声发射分析和原位扫描电子显微镜进行研究。PI的团队将制造具有纳米增强界面的层合复合材料，进行声发射研究，并推导出裂纹扩展的理论描述。凯泽斯劳滕小组将对材料进行微观结构和热机械表征，在扫描电子显微镜室内进行现场实验，并进行断口实验。

The goal of this collaboration between the PI and Klaus Friedrich of the Universitªt Kaiserslautern is to study micromechanisms of delamination in novel laminated compounds with nanoreinforced interfaces. A mat of nanofibers produced by electrospnning is used to suppress delamination and microcrack propagation. The interlaminar fracturing will be studied by state-of-the-art acoustic emission analysis and in- situ scanning electron microscopy. The PI's group will manufacture laminated composites with nanoreinforced interfaces, perform acoustic emission studies, and derive theoretical descriptions of crack propagation. The Kaiserslautern group will conduct microstructural and thermomechanical characterization of materials, perform in situ experiments in a scanning electron microscope chamber, and conduct fractographic experiments.
