Abstract

Stereo DIC is employed to quantify wrinkling on 6.35 mm wide and 0.16 mm thick carbon-epoxy tows during advanced fiber placement along straight and circular paths on a planar composite surface. Measurements obtained just after placement provide quantitative deformation fields, including the presence of out-of-plane wrinkles that occur during the placement process. Results show that wrinkles occur at locations where the substrate has defects. Results also show that wrinkles occur at other locations only when the radius of curvature is less than 2540 mm.
