New energy vehicle industry: current development state and issues
NING Taiyu;OUYANG Hongwu;CHEN Jiayi;OUYANG Xinyu;The development of new energy vehicles has become a core strategy for the Chinese automotive industry to achieve a competitive advantage. This paper analyzes the current development status of new energy vehicles in both domestic and international market, as well as the penetration modes of different levels of new energy vehicles in China. The results show that new energy vehicles have entered a period of fast penetration, and the production and sales volume have increased exponentially. In 2022, China's new energy vehicles accounted for 59% of the global market share, and the proportion is continuing to rise. The development of China's new energy vehicle market is becoming more diversified, with a penetration rate of 100% for A00-class and gradually penetrating into higher-class vehicle sectors. Chinese automobile companies have emerged strongly in the field of new energy vehicle market, with each showcasing their unique strengths, and the competition among companies is becoming increasingly fierce. We look forward to creating a new pattern of coordinated development and win-win cooperation.
Application of composite materials in large aircrafts
CHEN Yong;WU Guanghui;ZHONG Kelin;WANG Shihao;COMAC Shanghai Aircraft Design and Research Institute;Composite materials are widely used in large aircrafts at home and abroad, and the application of advanced composite materials is inseparable from the development of commercial aircrafts.While promoting the development and upgrading of commercial aircrafts, composite materials technology and manufacturing equipment are also constantly updating. Chinese large aircrafts started late such that the application of composite materials is basically catching up with the international trend. With the rapid development of composite materials, however, commercial large aircrafts have accelerated the application process of key components, and continue to gain innovation in the development.
