Advanced composite materials (ACM) have become the basic materials of the aerospace engineering. In this paper, the requirements and the applications of ACM in the aerospace engineering were presented. Some hot-spot technological fields, such as lattice materials and structures, nano-composite materials and multi-functional materials, were introduced. Their potential applications and developments were prospected. Finally, the problems to be resolved about raw materials, low cost, integration of design and evaluation in ACM were discussed.
