title = "Experimental investigation of the radius forming behavior of fiber reinforced thermoplastics",
abstract = "The following work focuses on the experimental analysis of the forming behavior of fiber reinforced thermoplastic layups with a special focus on the radii. Possible factors influencing the result and quality of the forming shall be investigated. Considered parameters were the thickness of the layups, the fiber orientation, the size of the radius and the preload of the layup. The layups were produced with a Fiberforge RELAY2000{\textregistered} ATL machine and consolidated in a heated hydraulic press as a subsequent step. The consolidated layups were then thermoformed using two matched dies. During the forming, the material was cooled down until it reached a solid state and could be removed from the mold. These test specimens were then analyzed regarding their draping pattern, occurring defects and forming quality using microsections and the optical analysis system ATOS by GOM. The investigations showed that especially the thickness of the layup and the size of the radius had an influence on the part quality. But also the fiber orientation affected the formation of imperfections. The preload of the layup was of less importance for the forming behavior.",
