| Abstract Scope |
The past decade has seen rapid growth in additive manufacturing (AM) using carbon fiber reinforced composite materials. Many researchers have studied alignment of chopped fibers in tracks printed via fused filament fabrication. However, several companies have introduced continuous fiber reinforced composite AM processes. Most of these systems constrain fiber placement to the X-Y build plane though. For non-planar fiber placement, algorithms to generate fiber routing toolpaths are still very much in their infancy. This paper will present recent work aimed at depositing conformal continuous fiber skins on non-planar surfaces in a way that evenly spaces fibers in regions where changes in surface curvature would normally result in bunching or spreading of fibers. Preliminary results using a multi-nozzle 5-axis FFF system will be presented. Results will include strategies to deposit conformal unidirectional layers with staggered orientations as well as 3D woven fiber surface layers. |
