Click on the DOI link to access this article at the publishers website (may not be free). ; Low-cost composite structures are highly demanded by the DoD and commercial industries to reduce total life cycle costs through the integration of automation and digital manufacturing of unitized composite parts. Automatic fiber placement (AFP) has been used extensively by major aerospace industries to produce large-scale composite structures. Through the automatic placement of fibers in different directions on the customized mold surface, full-scale unitized composite structures can be fabricated with higher production rates and in a highly controllable and repeatable manner. However, poor process planning and time-consuming, operator-dependent manual inspection can significantly interrupt the manufacturing process and increase the scrap rate due to intolerable levels of fabrication-induced defects. A demonstration of AFP technology was performed using a dual-material composite tapered beam. The performance of the as-built beam was evaluated using a physics-based failure prediction model under multiaxial loading. Our key research components include the fabrication of dual-material tapered beams using the improved AFP technology, performance of NDI inspection and characterization of fabrication-induced defects, development of a high-fidelity model with defects mapping, and performance of failure prediction under multiaxial loading. The predicted failure sequence and final rupture mechanisms are compared with the experimental observations. © 2025, American Institute of Aeronautics and Astronautics Inc, AIAA.
