TOPOLOGY OPTIMIZATION FOR MODELING AND PREDICTION OF COMPLEX FABRIC STRUCTURES AND PROPERTIES

A method for modeling textile structures using bicontinuous surfaces includes selecting a virtual scaffold of bicontinuous surfaces defining textile fabrication pathways to model spatial relationships between the pathways and yarns in a desired yarn pattern of a textile fabric design. The method further includes constructing a yarn pathway across the bicontinuous surfaces that form the virtual scaffold. The method further includes removing or releasing tension from the virtual scaffold, thereby allowing yarns to relax and determining a physical property of the textile fabric design.
