RP 14-2 – Extention of the Cyber-Physical Prefabrication Platform

Extension of the Cyber-Physical Prefabrication Platform

Research Project 14-2 (RP 14-2)

EXTENSION OF THE CYBER-PHYSICAL PREFABRICATION PLATFORM FOR RELIABLE PRODUCTION OF LARGE-SCALE FIBRE COMPOSITE BUILDING ELEMENTS USING CONVENTIONAL AND ALTERNATIVE MATERIAL SYSTEMS

In the previous Research Project (RP 14-1), a fabrication system for coreless filament winding (CFW) was developed and implemented, which allows the manufacturing of fibre components of different shapes with minimal formwork. The system consists of two container platforms, each equipped with a robot on a linear axis to enable the manufacturing of large-scale building components, and a filament placement head that allows passing between robots, on-head impregnation and tension control. While previous approaches have been stationary [1], the platform developed is portable and reconfigurable.

Although the current platform already enables manufacturing of large components, it has several limitations in terms of workpiece size, production speed, possible fibre network configurations/syntaxes, process predictability (and associated safety factors), use of more sustainable materials and ease of programming. Overcoming these limitations poses scientific challenges that will be addressed in this project by investigating the extension of the fabrication platform and associated fabrication space, as well as production speed, through robot teams and autonomous mobile robots. This will be complemented by path planning automation methods, the development of monitoring and compensation methods to reduce safety factors, and the exploration of fabricating with alternative fibre/matrix systems. The developments will be tested and evaluated in two demonstrators.

Evolving from automated Tape Laying Technology (ATL), AFP is a technology that not only mimics the manual laying process but also allows tailored fiber and tow alignment to deliver load-optimized patterns, stacking sequences and part structures leading to improved mechanical performance and significant waste reduction. The filament winding evolution towards automated Robotic Filament Winding put the technology in a position to manufacture highly complex lightweight structures in architecture. In this short review, recent developments in both automated fiber alignment technologies are presented and discussed, including the main advantages and materials used. Regarding the ATL and AFP process, developments in non-aerospace applications are considered. Besides a short overview of new placement technologies, advances in Tailored Fiber Placement (TFP) in the field of dry fiber placement are reported.

In this paper, a novel workflow to process and analyse the data sets in a unified reference frame is proposed. From this, differently sophisticated iteration loops can be derived. The developed methods are presented within a case study using coreless filament winding as an exemplary fabrication process within an architectural context. This additive manufacturing process, using fiber-reinforced plastics, exhibits great potential for efficient structures when its intrinsic parameter variations can be minimized. The presented method aims to make data sets comparable by identifying the steps each data set needs to undergo (acquisition, pre-processing, mapping, post-processing, analysis, and evaluation). These processes are imperative to provide the means to find domain interrelations, which in the future can provide quantitative results that will help to inform the design process, making it more reliable, and allowing for the reduction of safety factors.

The increasing demands on quality and the complexity of the processes cannot always be met by the range of functions that are available in numerical control systems. In the coreless winding of fiber-polymer composites, it is important to keep the roving tension as constant as possible while maintaining a high processing speed. Currently, the winding paths are programmed via a number of control points. This results in a trade-off between lower process properties and higher processing speed with fewer control points. Conversely, finer interpolation of the path can improve process characteristics at lower processing speeds. With interpolation methods that are adapted to the process, new possibilities open up to overcome these trade-offs. This paper presents a spline path planning algorithm based on clothoids. This algorithm considers both the process requirements and the dynamic characteristics of the manufacturing unit.

Overall, we find that synergy between academia and industry is essential to meeting research, productivity, and certification goals in the rather conservative building industry.}, author = {Bodea, Serban and Zechmeister, Christoph and Dambrosio, Niccolo and Dörstelmann, Moritz and Menges, Achim}, doi = {10.1016/j.autcon.2021.103649}, editor = {Skibniewski, Miroslaw J.}, issn = {0926-5805}, journal = {Automation in Construction}, month = {06}, pages = 103649, publisher = {Elsevier {BV}}, title = {Robotic coreless filament winding for hyperboloid tubular composite components in construction}, url = {https://doi.org/10.1016%2Fj.autcon.2021.103649}, volume = 126, year = 2021 }

  @article{Ellwein_2021, abstract = {The term co-design describes a collaborative design process, usually across the boundaries of individual areas. A major aspect, and often an obstacle in the implementation of the co-design approach, is the establishment of a centralized data management system. In the past, the data management concept has been approached from different perspectives. Current approaches usually are oriented along the process chain and thus reflect a unidirectional flow of information. Neither the information feedback nor the reaction to adjustments in upstream model steps is supported, which makes continuous collaboration more difficult and at best reduces the co-design approach for continuous data usage. This paper addresses these weaknesses while outlining an integrative data processing concept enabling co-design between the domains of construction and industrial prefabrication. Geometrical information generated during architectural design and construction planning is reused for the production of components, manufacturing-related design adjustments are transferred back into the domain of construction. Changes throughout the entire process are centrally recorded. To ensure independence from the software tools used and to consider their great diversity, data exchange is largely based on standards, namely industry foundation classes and the standard for the exchange of product model data. In order to counteract the sequential processing according to a waterfall model and to support the co-design approach, the industrial prefabrication toolchain, consisting of computer-aided manufacturing software and downstream postprocessors, is largely automated, so that reprocessing of a workpiece for minor geometric adjustments no longer requires any interaction of the production planner.}, author = {Ellwein, Carsten and Reichle, Alexander and Herschel, Melanie and Verl, Alexander}, doi = {10.1016/j.procir.2021.05.103}, journal = {Procedia CIRP}, note = {31st CIRP Design Conference 2021 (CIRP Design 2021)}, pages = {451-456}, publisher = {Elsevier {BV}}, title = {Integrative data processing for cyber-physical off-site and on-site construction promoting co-design}, url = {https://www.sciencedirect.com/science/article/pii/S2212827121005746}, volume = 100, year = 2021 }

  @inproceedings{Zechmeister_Design_2019, abstract = {The aim of this research is to showcase processes and methodologies for the design and development of long-span, core-less wound structural building elements for architectural applications. Departing from established, iterative design methods and a linear digital toolchain, integrative design strategies incorporate parameters like material and fabrication constraints, structural performance and architectural design from the very beginning, establishing feedback loops. This approach seems particularly promising with the architectural application of high performance, long-span fibre components in mind, given their vast range of different and often antagonistic requirements. Building upon previous research in the realm of fibre composites conducted at the Institute for Computational Design (ICD), novel strategies and methods for the design and development of long-span fibre composite components are discussed, based on the 2019 BUGA fibre pavilion, a full scale glass and carbon fibre structure developed for the Bundesgartenschau - a garden fair in Heilbronn, Germany.}, address = {Cham}, author = {Zechmeister, Christoph and Bodea, Serban and Dambrosio, Niccolo and Menges, Achim}, booktitle = {Impact: Design With All Senses}, doi = {https://doi.org/10.1007/978-3-030-29829-6_32}, editor = {Gengnagel, Christoph and Baverel, Olivier and Burry, Jane}, file = {33d58cca-d903-46b4-b579-5420b90a39ad:C\:\\Users\\ac131915\\AppData\\Local\\Swiss Academic Software\\Citavi 6\\ProjectCache\\amdi0te5hfdbkvr37r7ubdq1puiv7nkms1el1ieio\\Citavi Attachments\\33d58cca-d903-46b4-b579-5420b90a39ad.pdf:pdf}, isbn = {978-3-030-29829-6}, journal = {Proceedings of the Design Modelling Symposium, Berlin 2019}, pages = {401--415}, publisher = {Springer International Publishing}, title = {Design for Long-Span Core-Less Wound, Structural Composite Building Elements}, type = {Publication}, year = 2020 }
