Current status and development trend of advanced structural materials technology in aerospace field

Advanced materials technology is the forerunner in the development of high-tech aerospace equipment and the key foundational technology supporting the modern industry. It has penetrated into all aspects of national defense construction，national economy and social life，and has become a technological highland and national defense focus that countries all around the world are competing to develop. This article focuses on analyzing the current technological status and development trend of the advanced structural materials in the aerospace field，elaborating on the aspects of high-performance polymer and their composites，high-temperature and special metal structural materials，lightweight high-strength metals and their composites，and advanced structural ceramics and their composites. The analysis results show that the current development and production of aerospace structural materials in China still face various difficulties，such as too much follow-up research and imitation，lack of independent innovation，severe technological blockade，and technical bottlenecks need to be broken. Meanwhile，the prospects for future research and development are proposed，and the significance of establishing the complete technology system of production-learning-research-application is highlighted.
