| Abstract Scope |
Fiber-Reinforced Polymer Composite (FRPC) parts are predominantly laminates, shells, or surfaces wound with 2+D fiber patterns even after the emergence of additive manufacturing. Making FRPC parts with embedded continuous fibers in 3D is not reported previously even though topology optimization demonstrates that such designs are optimal. Earlier attempts in 3D fiber reinforcement include making parts with channels into which fibers are inserted or co-extruding fiber with resin. In this work, we developed a 3D printer and a process for concurrent embedding of spatially steered continuous fibers inside the matrix by extending vat photopolymerization. We embed a single continuous fiber spatially by using a robot to gradually steer the fiber as the part is built layer upon layer. We also show that multiple continuous fibers can be steered in a part. We tested a few parts for strength and stiffness to illustrate the importance of spatially embedding fibers in specific patterns. |
