Dr. Danielle Zeng is a Technical Expert at Ford Research & Innovation Center responsible for material
characterization and modeling method development including a variety of material systems such as aluminum, advanced high strength steels, and fiber reinforced composites. She holds a doctorate degree from The Ohio State University in 2000.
Dr. Zeng joined Ford Motor Company in 2003. In recent years, she is leading the company's effort intensively developing the Integrated Computational Materials Engineering (ICME) CAE tools for fiber reinforced composites. She has co-authored over 50 technical papers. Her major awards include the Sydney H. Melbourne Award and Henry Ford II Distinguished Award from American Society of Automotive Engineering (SAE); the best paper award from American Iron and Steel Institute (AISI); as well as three times of Henry Ford Technology Award, the highest technical honor bestowed at Ford Motor Company.
It is a strong demand and great challenge for both traditional and electrical vehicles to reduce the structure weight, promote the NVH and safety performance but still use the efficient and low-cost manufacturing process. The reasons are two-folds: (1). The highest strength of the traditional structure metal material applied in the vehicle is 1.5 GPa. Firstly, the development of such high strength metal is extremely challenging. Secondly, the stamping of advanced high-strength sheets with such strength is much more difficult owing to the poor workability of steels and a large amount of springback of the product. Such dilemmas make the selection of CFRP becomes an inevitable choice. (2). The conventional forming processes for the fabrication of CFRPs such as autoclave is a time-consumed progress which is not suitable for the mass production characteristic of the vehicle manufacturing. Thus, it will be urgently needed to develop the high-speed and low-cost manufacturing process to realize products with a strength of 2 GPa or more with high productivity that is expected to be required.
