High performance ceramics with high strength or hardness can withstand extremely severe shock loading, having been used in many critical protective applications. The rapid development of nanomaterials offers great potential for further improving the performance of protective materials to the next level. It has been confirmed both experimentally and theoretically that nanomaterials can exhibit much higher strength and/or hardness than their bulk parental counterparts, not only under general ambient conditions but also under high rate shock loadings. A recent Science paper has reported that ultra-high strength can be achieved for nanocrystalline materials under shock loading. Furthermore, composites allow for the combination of multiple advanced properties to produce a customisable behaviour. The increased utilization of such advanced ceramic composites under dynamic loading conditions requires an improved understanding of the relationship between high-rate/shockwave response as a function of micro-structure and even nano-structure. The corresponding relationship for single-phase materials is very different. In this context, three key Themes characterize the research: (1) design and synthesis of advanced nanocomposite materials; (2) elucidation and full (or fundamental) understanding of the nanostructure - shock response relationship; (3) prediction of the nanocomposites performance.

具有高强度或高硬度的高性能陶瓷可以承受极其严重的冲击载荷，已被用于许多关键的保护应用。纳米材料的快速发展为进一步提高防护材料的性能提供了巨大的潜力。实验和理论都证实，纳米材料不仅在一般环境条件下，而且在高速率冲击载荷下，都可以表现出比其本体母体对应物高得多的强度和/或硬度。最近的一篇科学论文报告说，在冲击载荷下，纳米晶材料可以实现超高强度。此外，复合材料允许多种先进性能的组合，以产生可定制的行为。这种先进的陶瓷复合材料在动态载荷条件下的利用率的增加，需要提高对高速率/冲击波响应之间的关系的理解，作为微观结构，甚至纳米结构的功能。单相材料的对应关系非常不同。在此背景下，三个关键主题表征了研究：（1）先进纳米复合材料的设计和合成;（2）阐明和充分（或基本）理解纳米结构-冲击响应关系;（3）预测纳米复合材料的性能。
