Filament winding is a well-established process to manufacture composite parts. With the advancement of automation and process control technologies, the winding of dry fibers to manufacture a preform for liquid composite molding (LCM) processes is feasible. This study presents an overview of dry fiber winding and explains the most important process aspects. It addresses the application of differential geometry to the winding technique. The formulation of geodesic and non-geodesic equations and their solution is discussed. Besides, nonanalytical methods to generate winding trajectories are introduced. The influence of the friction coefficient on process-related parameters is covered. Considering technology trends the study gives an overview of developments in winding systems and equipment. Novel research areas can be identified in the development of new path generation methods, considering detailed friction influences. Fiber depositing and guidance systems must also be adapted. Alternations of the process parameters and their influence on subsequent impregnation processes must be investigated.

“…The BUGA (Bundesgartenschau) Fibre pavilion is the latest in a series of collaborative research projects between the two institutes at the University of Stuttgart; the Institute for Computational Design (ICD) and the Institute of Building Structures and Structural Design (ITKE). The research aim is to generate lightweight lattice composite structures through the process of robotic coreless filament winding as described by La Magna et al 3 and Reichert et al 4 This technique allows the placement of fibre filaments between scaffold frames without the geometric limitation of a core. The shape of the structure gradually emerges from the interaction of these freely spanning fibres as they are progressively hooked by a robotic arm around winding anchor pins at the scaffold frames.…”

The BUGA fibre pavilion built in April 2019 at the Bundesgartenschau in Heilbronn, Germany, is the most recent coreless fibre winding research pavilion developed from the collaboration between ICD/ITKE at the University of Stuttgart. The research goal is to create lightweight and high-performance lattice composite structures through robotic fabrication. The pavilion is composed of 60 carbon and glass fibre components, and is covered by a prestressed ethylene tetrafluoroethylene (ETFE) membrane. Each of the components is hollow in section and bone-like in shape. They are joined through steel connectors at the intersecting nodes where the membrane is also supported through steel poles. The components are fabricated by coreless filament winding (CFW), a technique where fibre filaments impregnated with resin are wound freely between two rotating scaffolds by a robotic arm. This novel structural system constitutes a challenge for the designer when proving and documenting the load-carrying capacity of the design. This paper outlines and elaborates on the core methods and workflows followed for the structural design, optimization and detailing of the BUGA fibre pavilion.

Influence of the binder filtration on residual stresses at the composite constructions manufacturing

Stress changes generated during the composite winding on the mandrel surface is investigated. A model of liquid binder filtration through the fibrous filler in the form of disc-shaped gap in the structure of the coil-processing material is proposed. An equation, considering the stress decrease occurring in consequence of the coils winding due to binder filtration is suggested. Experimental results of unidirectional rings winding on mandrels studied using strain gages are demonstrated.
