Abstract
This paper presents preliminary work on modelling the deformation behaviour of 3D woven textile preforms. Idealised geometrical models have been developed using TexGen software, based on the nominal weave specifications. Dry textiles deform considerably even under modest loading applied during composites processing. Two different approaches have been presented here: analytical energy minimisation scheme and FE analysis. Kawabata Evaluation system (KES) has been used for evaluating the constitutive tow properties and the load-deformation behaviour of 3D weaves. The cross-section and the path of an individual tow depend on the thread-line tensions in 3D weave. In this work, an attempt has been made to measure the thread-line tensions using Raman spectroscopy.
