Performance Prediction for Non-standard Non-Crimped Fabrics

A method has been developed to characterize a non-crimped fabric material with any fiber orientation for a draping analysis. PAM-FORM, a draping simulation tool, was used to perform draping simulations using this characterization and the results were validated experimentally on an identical geometry. Results show that PAM-FORM can accurately predict the shearing behavior of non-crimped fabric materials but that it cannot predict wrinkle formation accurately if the fabric is stitched in a non-orthogonal manner..
