Implementing digital composite structure definition was the base of achieving the data integration of design, analysis and manufacture for aircraft composite structures. Basic elements of composite integration developing environment and integration developing flow are given and several key technologies are discussed. The digital compos-ite structure definition consists of the modeling of geometry and the modeling of material structure. The modeling process is summarized. According to the fact that the composite structures can not be analyzed today based on the final shape with true fiber orientations, the content and organization of interface data are summarized. By using automatic mapping of fiber orientation data to the finite element mesh, the automatic data transfer from design to analysis is real-ized. At last, the data content and integration style of design and nesting and cutting system, design and laser projec-tion system are studied.
