Biography

Dr. Hao joined at University of Exeter on Sep. 2005 and his research works have engaged in the Advanced Materials and Manufacturing with regard to life sciences and aerospace industry. He graduated in 1995 from Huazhong University of Science and Technology, China and completed his PhD study on ‘Laser Surface Modification of Bone-Implant Materials’ in Nanyang Technological University, Singapore in 2004. He has also developed selective laser sintering (SLS) technique for rapid manufacturing of tailor-made bioactive implants using hydroxyapatite (HA)/polymer composites at Loughborough University, UK from 10/2004 to 09/2006. Dr. Hao has published over thirty journal papers, plus one book and two book chapters.

Current Projects

AVLAM-Added Value by Laser Assisted Additive Manufacture: The AVLAM is funded by Technology Strategy Board (TSB) and supported by leading industrialists: The Welding Institute (TWI), EADS (Airbus UK Ltd), Bombardier Aerospace, TISICS Ltd and Materialise UK. This three year project will develop additive layer manufacturing technologies to produce high performance and high value aerospace components by enhancing process capability and unlocking new design opportunities. The research in Exeter will investigate the laser-materials interactions, improve the process accuracy and surface quality of the components, characterise the microstructures and mechanical properties and develop additive manufacture process for metal matrix materials.

Optimisation Techniques for Porous Materials and Composite Materials Development: This project is funded by EPSRC Case Award and collaborated with Simpleware to develop topological optimisation techniques to design, model, optimise and characterise porous structural materials, in particular for porous micro-structures. The research will investigate two main types of topology optimisation: evolutionary and homogenisation based techniques and couple with grid based meshing and finite element analysis. The techniques will be developed for bone remodelling and bone tissue scaffolds application and may be also applied to produce light-weight micro-structures for aerospace components.

Formulation of Complex Material Structures for Tailored Mechanical Properties: This project is funded by Great West Research and collaborated with EAD to investigate design, optimisation and fabrication approach for producing novel aerospace composite materials featuring optimised geometries with hierarchical internal cellular structures using Additive Layer Manufacturing techniques. The development will lead to the innovative structure arrangements for aerospace components which can exhibit advanced engineering performance.

Additive Layer Manufacturing of Aerospace Components: This is a PhD project funded by the School of Engineering, Computing and Mathematics to investigate and develop the application of newly developed additive layer manufacturing (ALM) technologies for the direct manufacture of net-shape and high performance aerospace components. The experimental investigation will be carried out to identify the suitable and optimal processing parameters to consolidate aerospace materials using selective laser melting, laser consolidation and selective laser sintering process. It will then concentrate on developing new materials such as metallic powder mixtures, metallic matrix composites for these ALM processes with the objective of improving and tailoring the properties of the aerospace components made by ALM technologies.

ChocALM-Chocolate Additive Layer Manufacturing: This is a MEng final year group student project and will be carried out over three years to develop a novel ChocALM system to produce personalised chocolate products using ALM technique. The first-year project has produced a machine prototyping to deposit chocolate and form 3D objects and sponsored by Cadbury Schweppes, Farnell and Hepco. This academic year will further develop two deposition system and refine the system to make quality and tasty chocolate products. The detail of this project can be found on http://chocalm.org/joomla/.
