Elucidation of strengthening and damage mechanisms of dissimilar joining technology utilizing 3D nano-structure

该项目考虑了直接结合纳米结构铝和碳增强热塑性塑料（CFRTP）的损伤和强化机制的阐明。在Spring-8进行了同步辐射X射线断层扫描实验，发现开发的键合方法导致CFRTP内部发生开裂，而不是由于非常强的键合而发生在界面处。进行了各种有限元建模研究，使用粘性元素连接实验和理论，并开发了一种新的测试方法，更精确地评价界面性能。这项工作产生了几份期刊论文，目前正处于审查进程的最后阶段。

The project considered elucidation of damage and strengthening mechanisms of directly bonded nanostructured aluminium and carbon reinforced thermoplastics (CFRTP). Synchrotron X-ray tomography experiments were carried out at Spring-8, and it was found that the developed bonding method lead to cracking occurring inside the CFRTP rather than at the interface due to the very strong bond. Various finite element modelling studies using cohesive elements were carried out to link experiments and theory, and a novel test method was developed for more precise evaluation of the interface properties. The work resulted in several journal papers currently in the last stage of the review process.
