Abstract

The simulation of Liquid Composite Moulding (LCM) processing is becoming increasingly important due to growing demand for large, complex and low-cost composite aerostructures. This research combines work from a range of disciplines in order to demonstrate a Complete Process Model (CPM) for LCM manufacturing with textile reinforcement materials. Experimental characterisation of a carbon fibre plain weave fabric provides detailed tensile, shear and permeability properties for use in numerical draping and infusion models. By combining shear deformation results from an Abaqus draping model with deformation-dependent permeability properties, a detailed distribution of flow properties can be defined for the ANSYS Fluent infusion model. This innovation is validated against full-scale, complex vacuum infusion experiments, and demonstrates a significant improvement over traditional modelling approaches.
