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.

该项目考虑阐明直接粘合纳米结构铝和碳增强热塑性塑料（CFRTP）的损伤和强化机制。在Spring-8上进行了同步加速器X射线断层扫描实验，发现由于结合力非常强，所开发的结合方法导致CFRTP内部出现裂纹，而不是界面处。使用粘性单元进行了各种有限元建模研究，将实验和理论联系起来，并开发了一种新的测试方法来更精确地评​​估界面特性。这项工作产生了几篇期刊论文，目前正处于评审过程的最后阶段。
