Recent studies reveal that alternating electric or magnetic fields can rotate conductive nanofillers in polymers. This project aims to advance a new concept of aligning nano-scale reinforcements (for example, graphene nano-sheets and carbon nanofibres) along the thickness direction of composite materials. The alignment of nano-sized reinforcement will address the perennial problem of through-thickness weaknesses of fibre-reinforced composites and, at the same time, improve the electrical conductivity of composites. The synergistic improvements in the mechanical and electrical properties will improve damage tolerance and diagnosis of composites, thus expanding their applications in transport and civil construction to help reduce carbon dioxide emission.

最近的研究表明，交变电场或磁场可以旋转聚合物中的导电纳米填料。该项目旨在提出一种沿着复合材料厚度方向排列纳米级增强体（例如石墨烯纳米片和碳纳米纤维）的新概念。纳米尺寸增强体的排列将解决纤维增强复合材料的贯穿厚度弱点的长期问题，同时提高复合材料的导电性。机械和电气性能的协同改善将提高复合材料的损伤容限和诊断能力，从而扩大其在交通和民用建筑中的应用，以帮助减少二氧化碳排放。
