The lightweight features and unique mechanical properties of CFRP are attributed to their multi-component structure, however, the composite structure also imposes performance limitations. The failure behavior of CFRP is influenced by the properties of matrix resin, fibers, fiber-resin interfaces, and the relative geometric alignment of fibers. Despite extensive research, a gap remains in understanding how the spatial distribution of composite constituents affects crack initiation and propagation. In this paper, we established an innovative scoring method to assess fiber alignment in CFRP using persistent homology, provided a fundamental understanding of the crack propagation mechanism.
