Abstract: Optimization through Fiber Steering for Continuous Fiber Composite Applications Continuous carbon fiber composites offer significant opportunities for designers to create optimized components utilizing individually steered tows. Aerospace-grade unidirectional continuous fiber reinforced materials are upwards of 40 times stronger and 18 times stiffer in the longitudinal direction compared to transverse. Fiber-steered manufacturing approaches such as 3D printing and design tools such as topology optimization allow for maximum strength and stiffness and lowest weight of a final component by steering fibers longitudinally in the direction of importance, but these opportunities present a challenge for design engineers. Harnessing the novel capabilities provided by individual fiber design requires knowledge of the physical constraints related to the fiber, as well as the constraints of the additive manufacturing process. This paper will discuss what parameters a designer must consider in their design – bend radii, overhang angles, tow cross sections, surface finishes, fiber intersections, printer geometries and others- to achieve a successful final component. Case studies of actual parts and test results will be presented in addition to best practices for design of continuous carbon fiber steered composites. Continuous Composites Inc, based in Coeur d’Alene, ID, is the developer of the CF3D Enterprise™, a disruptive additive manufacturing system for composite production.
