Prof. Fu Mingwang, Professor, Department of Mechanical Engineering, in collaboration with Prof. Shi San Qiang, Chair Professor and Head of Department of Mechanical Engineering, has been awarded a RMB$3 million worth, five-year grant (2019.01-2023.12) for a research project “ Research on the theories and technological fundamentals in integrated  plastic forming of shape and tailoring of property of cross-scale structures” (跨尺度構件形性協同塑性成形理論及技術基礎研究).  The project is a key project funded by the National Natural Science Foundation of China (國家自然科學基金會, NSFC).

Metal Forming is one of the most important manufacturing processes widely used in many industrial clusters, especially in auto and aerospace industries. Currently, this process has been extensively used in making meso- and micro-scaled parts or macro-scaled structures but with miniaturized features in tandem with product miniaturization in many industrial clusters.  Product miniaturization is an overwhelming trend due to the escalating concern about environment impact, energy consumption and materials usage and thus multi-scale manufacturing including meso- and micro-scale is getting crucial.  On the other hand, many cross-scale parts and components with macro-scale dimensions and plenty of meso- and micros-scaled geometry features, such as metallic bipolar plates (BPPs) for fuel cell, have been widely used in different industrial scenarios. The cross-scale manufacturing is also becoming critical. Therefore, multi-scale and cross-scale manufacturing is an efficient manufacturing solution for product miniaturization.  In multi- and cross-scale manufacturing, there are some unique and eluded phenomena involved, which must be physically understood and scientifically articulated for innovative and synergic shape forming and property tailoring of the deformed parts in different scales.   Prof. Fu and his research team aims to develop a  forming technology for synergic forming of shape and geometry, and the simultaneous tailoring of the quality and property of the deformed parts in multi-scales. By using three typical parts with multi- and cross-scales as case studies, the above developed theories for dealing size effect and its affected phenomena will be validated and verified. These theories will be deployed to the study and development of the needed technologies to make three case study parts with focusing on synergic and precision forming of shape and accurate tailoring of their quality and property, and further addressing the bottleneck issues arising in making these parts.
