Professor Zhang Guoqing, first-level full-time chief of Beijing Institute of Aeronautical Materials, Professor Wang Qi'an, former director of National remote Sensing Center of Ministry of Science and Technology, Professor Sun Baode, dean of School of Materials, Shanghai Jiaotong University, Professor Gu Dongdong, dean of School of Materials, Nanjing University of Aeronautics and Astronautics, Professor Fan Guohua, research and development director of Yangtze River Delta Advanced Materials Research Institute, Professor Yan Peijie, general manager of Suzhou Yichuangte Intelligent Manufacturing Co., Ltd., were invited to the meeting. Wang Chungeng, Deputy Director of the Achievement Department of Wuxi Science and Technology Bureau, Lin Yuxia, researcher of Industry-University Research Department of Wuxi Science and Technology Innovation Center, Jinlan Section of Science and Technology Bureau of Wuxi High-tech Zone (Xinwu District), Ye Fang Section Chief and Zhu Ping Deputy Section Chief of Hongshan Street Science and Technology Management Section of Xinwu District came to guide.
At the beginning of the launch meeting, Shen Yulan, general manager of Fei'erkang Company, delivered a welcome speech and introduced the development of the company in recent years. Fei'erkang, China's leading provider of complete solutions for metal augmentation manufacturing technology, has been working with Comac since 2013 to explore the SLM The application of 3D printing technology to domestic large aircraft. After more than ten years of development and efforts, titanium alloy powders and parts for 3D printing that meet international aviation standards have been supplied in batches. In 2019, Fei'erkang completed the reform of mixed ownership and continued to increase investment in technological research and development and production scale. Since its establishment, the company has the printing ability of more than 40 kinds of metal materials, such as titanium alloy, aluminum alloy, superalloy, stainless steel and so on. completed the metal 3D printing laser parameter development and optimization, processing platform stability verification, post-treatment process development and optimization, surface treatment process development and optimization, breaking through the metal 3D printing process stability, consistency, repeatability and shape control and other problems. General Manager Shen said that the company will rely on the advanced scientific research platform and gather a team of first-class experts to jointly carry out this major scientific research task, promote the technological development of the industry, and serve the major needs of the country.
researcher Zhang Guoqing and other experts attending the meeting fully affirmed the significance of this project and hoped that the project team would further refine the project implementation plan and complete R & D tasks with high standards and strict requirements in strict accordance with the requirements of national key R & D plan management measures and financial management methods.
At the discussion meeting on the implementation plan of the project, Zhou Dejing, head of the project and director of the Research Institute of Fei'erkang Company, introduced the overall implementation plan of the project, and the person in charge of each project reported in detail on the research content, task decomposition, specific implementation plan, expected results and assessment methods of each task. The experts at the meeting listened carefully to the project team's report and discussed and demonstrated the implementation plan. The project expert group fully affirmed the project plan and gave constructive guidance and suggestions on the division of tasks, the project interface, the form of achievements and the improvement of the technical scheme.
Research background and objectives of
large aircraft industry is a new industry driven by national will and of great strategic significance. 3D printing technology has a broad application prospect in large aircraft industry because of its great lightweight potential and high degree of freedom of design. In view of the urgent demand of large civil aircraft for batch titanium alloy powder and 3D printing components with high stability, it is urgent to carry out the research on the whole process control and optimization of titanium alloy 3D printing. The purpose of this project is to integrate big data and on-line monitoring technology, break through the efficient stable preparation, detection and evaluation technology of high-quality titanium alloy powder and 3D printing components, and realize the batch application of typical components in C919 aircraft. promote the great-leap-forward development of civil aviation.
Expected results and benefits of
has built an airworthiness demonstration line with an annual output of 60 tons of titanium alloy powder and 5000 3D printing components.
establishes no less than 3 technical specifications for titanium alloy powder and 3D printing components that meet the airworthiness requirements.
has completed the batch application of no less than 5 typical 3D printing parts on C919 aircraft.
this project is the first "national key R & D plan" project led by Fei'erkang, with the participation of 9 superior units in the industry, including the Yangtze River Delta Advanced Materials Research Institute, AVIC Beijing Aeronautical Materials Research Institute and Comac Shanghai aircraft Design and Research Institute. The commitment and smooth start-up of this project is an important embodiment of Fei'erkang 's ability to organize major national projects and serve the major needs of the country, and also marks the company has entered a new stage of high-quality development. In the future, Fei'erkang will continue to give full play to its advantages in products and services, and finally achieve the high-quality development goal of quality improvement, efficiency and coordination.
