Current research focused on three primary areas:
This focus of this research is to develop multiscale modeling framework to simulate the draping behavior of composite textiles such as woven fabrics, non-crimp fabrics, and unidirectional fabrics. This modeling framework was constructed by seamlessly connecting a micromechanics model developed based on SwiftComp and a draping model developed based on PAM-FORM. The open source code TexGen was used to generate the microstructure of unit cell of composite textiles. This modeling technique aims to provide an efficient and accurate computational tool to evaluate the draping behavior of composite textiles.
A thermoforming model was built based on PAM-FORM to analyze the thermo-formability and predict the final fiber orientations of textile reinforced polymer for automotive applications. The variations of material properties of textile reinforced polymer with temperature were predicted by a micromechanics model and verified by the experimental results. The goal of the development of this model is to help industry choose right tooling design and material properties.
This research focuses on creating a model chain by connecting PAM-FORM, PAM-RTM, COMPRO, SwiftComp, and ABQUS. The simulations performed by each software are connected by information flowing through different software. This model chain is expected to predict the influences of manufacturing processes from draping to demolding on the performance of textile reinforced composite structures made by resin transfer molding (RTM).
