Abstract:
High-resolution X-Ray computed tomography have demonstrated a unique ability to accurately detect and quantify critical subsurface irregularities, such as voids, waviness, and service damage in composites. While significant progress has been made in the respective areas of characterization and failure predictions, integrating 3D material characterization and non-destructive inspection of composites at the coupon scale into a comprehensive methodology applicable to failure prognosis of composite structures has yet to be developed. Such integration is especially important for the additively manufactured continuous fiber-reinforced thermoplastics that are often built with specific microstructural irregularities, such as voids, ply and fiber waviness, geometric errors, and variability of individual layers. The objective of this work is to provide a comprehensive description of novel modeling techniques used for the automated generation of structured mesh FE models for composite laminates that include as-designed and as-manufactured conditions while maintaining high-fidelity definition of model properties needed for the accurate predictions of structural performance.
