Abstract

This research presents the development of an analytical model to predict the elastic stiffness performanceof orthogonal interlock bound 3D woven composites as a consequence of altering the weaving parametersand constituent material types.The present approach formulates expressions at the micro level with the aim of calculating more representativevolume fractions of a group of elements to the layer. The rationale in representing the volumefractions within the unit cell more accurately was to improve the elastic stiffness predictions comparedto existing analytical modelling approaches.The models developed in this work show good agreement between experimental data and improvementon existing predicted values by models published in literature.
