Abstract

In this study, a constitutive model to predict shear force versus shear angle for a viscous textile composite sheet is developed, based on fibre volume fraction, textile architecture and matrix rheology. The model is evaluated using results obtained for a pre-consolidated 2×2 twill weave glass/polypropylene thermoplastic textile composite and a 5-harness satin weave carbon/epoxy thermoset prepreg. The model is based on an adaptation of uniaxial continuum theory for continuous fibre-reinforced composites. Meso- and micro-kinematics of deformation are considered in determining contributions to energy dissipation during shear. Contributions from a number of sources are included, representing shearing of the matrix between and within tows and also at tow crossovers. The model can represent the effects on shear resistance due to forming conditions (temperature and rate) through incorporation of the matrix rheology. As this is fundamentally a predictive modelling approach, it should facilitate the improved design of materials and optimisation of component manufacture.
