Based on the analysis of the composite material and its advanced manufacturing technology

with the process of fiber placement

an analysis technology of composite material fiber placement based on triangular mesh was proposed. The paper summarizes the current approach and the equidistant path planning method integrating the analysis mechanism

and we analyzed the targets of turning radius and angular deviation on the center lines. Through the result of analysis

we established the partition mechanism. With the mechanism

the original surface area of the ply was divided into some sectors independent to fiber geometry generation to improve the quality of the composite product. The CATIA secondary development tool CAA was used to realize the function of generation and analysis of the fiber geometry on the Microsoft Visual Studio 2005 platform

and the correctness of the analysis result and the partition result was validated. This research provides an important idea for the development of advanced manufacturing technology of composite materials.
