Abstract: This paper briefly reviews mechanics problems related to applicationsof advanced composite materials in thestructures of modern large aircraft, including the manufacturing andprocessing, trans-scale material/structural integrated design andcharacterization of materials properties, high-efficiency structural designand analysis, damage tolerance and durability, and safety monitoring andmanagement systems. It is shown that there is a strongneed for domestic researchers and engineers to work together to advance theresearch and applications of advanced composite materials so as to ensurethat they play an important role in the development oflarge aircraft in China.
