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

该项目考虑阐明直接结合的纳米结构铝和碳增强热塑性塑料(CFRTP)的破坏和加固机制。在Spring-8上进行了同步辐射X射线层析实验，结果发现，由于非常强的键合，所开发的粘接方法导致CFRTP内部而不是界面处发生裂纹。利用粘结单元进行了各种有限元模拟研究，将实验和理论联系起来，并开发了一种新的试验方法，以更准确地评估界面性能。这项工作产生了几篇期刊论文，目前处于审查过程的最后阶段。

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.
