Abstract
A method for rapid reconstruction of a woven composite material microstructure based on topological features is provided. First, geometric modeling is performed according to the topological features of fiber bundles and matrix in a woven composite structure, then the topological features are identified on the basis of a μ-computed tomography (CT) sequence image, the change laws of the features are extracted, and finally, a geometric model is reconstructed to complete the modeling of a microstructure. Compared with the structure modeling method based on weaving process parameters, the consistency between the reconstructed model and a real woven structure is improved, facilitating the improvement of the accuracy of the subsequent calculation of the mechanical properties of the material; and compared with the method for structure reconstruction directly on the basis of a μCT image, a tedious point cloud data process is simplified and calculation costs are greatly reduced.
