Prediction and validation of macroscopic mechanical properties of aramid fabric based on conformal mesh
摘要
Abstract
To address the difficulty in predicting the macroscale mechanical properties of aramid woven fabric caused by its complex woven architecture and significant inter-yarn friction effects,a conforming-mesh modeling method was devel-oped for the macroscale property prediction of matrix-free aramid woven structures.The method employs solid elements to-gether with an explicit frictional contact modeling strategy,enabling the slip and interaction behaviors among yarns to be captured.Compared with conventional bonded models with matrix constraints or voxel-based modeling approaches,it ex-hibits clear advantages in terms of geometric fidelity and physical consistency.In addition,the model predictions were vali-dated through tensile tests.The results show that the established model can reasonably reproduce the deformation and me-chanical response characteristics of aramid woven structures under loading,and that the predicted elastic properties agree well with the experimental results,with an error of only 1.5％.These findings demonstrate that the proposed method can accurately predict the macroscale mechanical properties of aramid woven fabric while retaining the geometric features of the woven architecture and the yarn contact effects,thereby providing a reliable theoretical basis and engineering support for the design of Composite hoses and the equivalent characterization of material parameters.关键词
