| Abstract Scope |
Because of the anisotropic properties of carbon fiber reinforced polymer (CRFP) composites, novel layup architectures, such as tow-steering, can be used to tailor mechanical properties of the composite structure to the loading condition during use. In this work, two tow-steered composite panels were designed, laid up using the Integrated Structural Assembly of Advanced Composites (ISAAC) automated fiber placement (AFP) machine located at the NASA Langley Research Center, and cured while simultaneously being inspected using an ultrasonic inspection system operating inside the autoclave. The first composite panel served as the “pristine” laminate containing only the overlaps that were intrinsic to the tow-steered design and the second panel had intentionally introduced layup defects including folds, wrinkles, splices, tow twists, foreign object debris (FOD), gaps, and additional overlaps. The inspections during the cure cycle focused on the area within the “defect” laminate containing folds and intrinsic overlaps. The ultrasonic inspections performed during the cure cycle were analyzed and compared to post-cure ultrasonic inspections of the entire laminate. |
