Abstract Scope |
During thermoplastic manufacturing using Automated Fiber Placement (AFP), a critical quality indicator is the degree of crystallization. Proper crystallization development promotes the in-situ curing process, in turn decreasing cycle times and production costs. Previous work has been established to determine crystallinity in AFP and other composite manufacturing processes but does not fully explore effects of heat mechanism inputs such as voltage and speed. Additionally, the formation of crystalline structures for newer heating mechanisms, such as pulsed light heaters, is not fully understood. This paper proposes coupling of a numerically based heat transfer model for the Excelitas humm3® pulsed light heater and a crystallization kinetic model to optimize AFP process parameters. 1D and 2D analyses by the kinetic model are conducted to visualize crystallization through the substrate thickness. Furthermore, by analyzing temperature evolution in response to variations in voltage and speed, an optimal processing window can be identified that enhances crystallization development. The proposed methodology facilitates rapid and efficient creation of manufacturing strategies with an optimal degree of crystallization. |
