Geometrical Modeling and Performance Analysis of Textile Composites Using Python Scripted Software Platforms

Textile-reinforced composites offer enhanced strength to weight ratio, bidirectional strength and impact resistance available with multiple weaving patterns and orientations as three-dimensional (3D) orthogonal, angle interlock, two-dimensional (2D) fabrics, etc. To ensure the applicability of these composites, mechanical characterization is performed prior to use. This study aims at exploring all the geometrical modeling utilities including yarn geometry, weaving patterns, binder yarn details and interpolations between yarn nodes, available with the modeling tool and their characterization using finite element (FE) post-processor tools by assigning boundary, loading and constraint conditions, both Python encrypted tools. Textile fabrics are modeled as representative element volume (REV)/unit cell (using Graphical User Interface, Python script or C++ API functions), exported to Python encrypted FE tool for characterization. Further, REV is repeated in desired orientations to replicate the overall fabric characteristics.
