Modelling fracture within 3D woven composites is a significant challenge and the subject of ongoing research due to their complex hierarchical structures. This challenge is heightened when modelling 3D woven composites with multiple fibre types, referred to as fibre-hybrid 3D woven composites. This work addresses this challenge through the development of a novel methodology for modelling fracture in fibre-hybrid 3D woven composites. The bulk of preceding research into fracture modelling of 3D woven composites has focused on single-fibre-type woven composites with limited research into fibre-hybrid 3D woven composites. Research has focused on highly simplified models, often relying on experimental results [1], [2], [3]. In contrast, this work will apply fracture modelling techniques to high-fidelity finite element models of 3D woven composites resulting in simulations of fracture behaviour comparable to the behaviour observed in experimental tests. 3D woven composites possess exceptional properties such as improved out-of-plane strength, stiffness, fracture toughness, fatigue resistance and damage tolerance compared to more traditional 2D woven composites [4], [5], [6], [7]. However, currently the use of 3D woven composites in industry is limited by a lack of knowledge about their behaviour. Manufacturing and testing the required number of samples is prohibitively expensive and time-consuming resulting in the need for accurate models of 3D woven composite behaviour. The novel fracture model for fibre-hybrid 3D woven composites developed in this work will serve as a foundational tool for developing new material designs, paving the way for innovation and the widespread adoption of 3D woven composites in a diverse range of industries.
