N2 - This study presents the experimental and numerical characterization of composite laminates manufactured using a novel method known as Advanced Placed Ply (AP-PLY). The behavior of cross-ply and quasi-isotropic AP-PLY laminates under uniaxial tension is compared with that of baseline laminates. Stiffness is found to be unaffected by the preforming process, while the strength is dependent on the laminate configuration. A 3D multiscale numerical modeling framework is developed to capture the effect of the through-thickness fiber undulations present in the AP-PLY composites. The ability of the framework to accurately predict the stress-strain behavior and failure mechanisms at a relatively low computational cost is demonstrated. The approach is also exploited to investigate the influence of design parameters and improve the strength of the laminates. These results show the potential of the numerical framework to optimize the fiber placement preforming process to design AP-PLY components for structural applications.
