Development of an agile system of objectives in the interdisciplinary development of CoDiCoFRP structures

Advisors: Albers (IPEK), Behdinan (UToronto)

The integrated engineering and design process of components and systems made of CoDiCoFRP (Continuous-DisContinuous Fiber Reinforced Polymer) is very complex and needs methodical support for the management of the related knowledge. This knowledge includes materials, technologies, modeling and simulation techniques as well as their application and integration into the synthesis of embodiment design. For that, system engineers need the ability to identify and model the requirements and boundary conditions (e.g., maximum bead height and planar component surface for handling system) consistently in the system of objectives, and to design CoDiCoFRP without being expert in all material specific fields. The research environment with the four research areas (Characteristic – C, Simulation – S, Technology – T, Design – D) and, especially, the development process of the reference structure (demonstrator part to visualize the achievements in the design and fabrication with CoDiCoFRP) will be used as a live-lab. This live-lab will be utilized to research the necessary methods and tools for the conclusive modeling of the system of objectives and management of the knowledge generated continuously and individually in the subprojects. Based on the knowledge of the first generation, methods such as expert surveys (industry advisory board), analysis of real FRP development processes in industry, Data-Mining, scenario technology, etc. will be used. Based on those results, general requirements (e.g., optimized component design by taking into account the anisotropic material properties) are derived and assigned to the individual doctoral projects (C, S, T, D). Major focus is on a lifetime model (C3), parameters of full-field simulations (S2) and requirements of processing rules (T1). Parallel to this, the generated knowledge in the individual doctoral projects is analyzed and translated into specific requirements (e.g., fiber orientation and bead height). The reference structure is exemplarily used to validate the consistency of the system of objectives with a focus on the dynamic development and applicability of the continuously generated knowledge with an agile development approach in order to support the decision-making process in embodiment design.
