An Adaptive RVE Generation Algorithm for CFRP Composites Considering Pore Morphology and Spatial Statistics

Article Preview

Abstract:

Manufacturing induced defects such as voids and non-uniform fiber distributions significantly affect the mechanical behavior of fiber reinforced polymer composites. However, generating high-fidelity representative volume elements (RVEs) that simultaneously capture fiber randomness and void characteristics remains a key challenge. In this work, we propose a novel adaptive fiber void generation (AFVG) algorithm to construct two-dimensional RVEs incorporating statistically controlled elliptical pores and randomly packed fibers. Based on an improved greedy placement scheme, the method integrates customized scoring functions and constraint checks to ensure realistic void morphology, orientation randomness, and fiber void spatial relationships, while maintaining target fiber volume fraction and porosity. The algorithm’s robustness is verified by spatial randomness metrics, and its effectiveness is demonstrated through finite element homogenization to predict the effective elastic moduli. Results confirm that the proposed method achieves high fiber packing efficiency and incorporates realistic void characteristics, providing a practical and extensible tool for multiscale modeling of composites with manufacturing defects.
