Schematic of 3D NPR CFRP with lattice structure
Prof. Hong Hu recently secured research funds from the National Natural Science Foundation of China (NSFC)/Research Grants Council (RGC) Joint Research Scheme (JRS) based on a proposal titled “Micro Optimal Design Strategy for High Performance Three-dimensional Negative Poisson’s Ratio (NPR) Lattice Structures”. The NSFC/RGC Joint Research Scheme aims to promote collaboration between researchers/research teams in Hong Kong and Mainland China that would mutually complement the existing strengths of both parties, and supports research proposals jointly submitted by Mainland Chinese and Hong Kong researchers. The success rate of securing this highly competitive funding source is only about 15%. In collaboration with Professor Jian Xiong of the Centre for Composite Materials and Structures (CCMS) at the Harbin Institute of Technology (HIT), the proposed project aims to develop a special class of 3D negative Poisson’s ratio (NPR) carbon fiber reinforced composite (CFRP) with a lattice structure (Fig. 1) that can simultaneously bear high loads and absorb energy. The project also aims to systematically study the mechanical performance of this structure under static and dynamic loading conditions. This study will advance and guide the design, fabrication, and application of 3D NPR lattice structures for engineering applications. The duration of the project is 4 years starting from 01/01/2021 and ending 31/12/2024.
