VIRTUAL TEXTILE COMPOSITES SOFTWARE WISETEX: INTEGRATION WITH MICROMECHANICAL, PERMEABILITY AND STRUCTURAL ANALYSIS

摘要

Internal geometry of textile reinforcement is an important factor of the reinforcement performance during the composite manufacturing and in the service life of the composite material. When a 3D shaped composite part is concerned, the reinforced is locally deformed (compressed, stretched and sheared), and the geometrical model should account for this deformation. The software package WiseTex implements a generalised description of internal structure of textile reinforcement on the unit cell level, integrated with mechanical models of relaxed and deformed state of 2D and 3D woven, two- and three-axial braided, weft-knitted and non-crimp warp-knit stitched fabrics and laminates. It is integrated with modelling of resin flow, micro-mechanical calculations of properties of composite and micromacro analysis of composite parts, finite element models and virtual reality software. The paper describes this family of models, which use a unified description of the geometry of the reinforcement unit cell.
