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.

具有高强度或硬度的高性能陶瓷可以承受非常严重的冲击载荷，并且已用于许多关键的保护性应用中。纳米材料的快速发展为将保护材料的性能进一步提高到一个新的水平提供了巨大的潜力。从实验和理论上证实，纳米材料的强度和/或硬度都比其散装父母的强度和/或硬度更高，不仅在一般的环境条件下，而且在高速冲击载荷下。最近的一份科学论文报道说，在冲击载荷下，纳米晶体材料可以实现超高强度。此外，复合材料允许多个高级属性的组合产生可自定义的行为。在动态载荷条件下，这种先进的陶瓷复合材料的利用增加需要提高人们对高速/冲击波响应之间关系的理解，这是微结构甚至纳米结构的函数。单相材料的相应关系非常不同。在这种情况下，三个关键主题表征了研究：（1）高级纳米复合材料的设计和合成； （2）对纳米结构的阐明和完全（或基本的）理解 - 冲击响应关系； （3）纳米复合材料性能的预测。
