Abstract
Automated Fiber Placement (AFP) has become a leading manufacturing process for the production of large composite structures. The resulting structures constructed through AFP typically have a number of defects embedded in the part from the manufacturing process. These defects can have adverse effects on the stiffness and strength properties of the part. Therefore, there is often some attempt to repair and correct defects while the part is still in the green state. To generate insights into the outcome of rework and repair, manual rework was performed on an AFP manufactured doubly-curved part and inspected both before and after manual rework. Rework was performed by two operators with an assortment of hand tools including a roller and heat gun. Inspection was conducted using an automated defect detection system coupled with a data acquisition system consisting of robot-actuated laser profilometers. The resulting comparisons from before and after rework inform the size, type, and location of repairable defects and highlights cases where repair is inconsequential or even negative to the overall quality of the laminate. Key metrics such as Intersection over Union (IoU) and total defect coverage reduction are presented as potential methods for analysis.
