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.

In this paper are presented aspects concerning robots trajectory planning for winding carbon wire around of a die, to obtain a composite structure which is used in automotive industry. One of the goals of the research is to realize parts using robots for creating one part and in the same time to optimize the cycle time comparing with manual method. Another goal of this study is to obtain a high accuracy of robot trajectory. This aspect is important because the shape of the final die is asymmetric and the robot tool must travel through small area. In this study are proposed new methods of robots cooperation and trajectory planning. For higher accuracy of the trajectory was introduced the virtual space for designing and testing the trajectory and then transpose in real space. Furthermore are carried out tests to prove the efficiency of proposed method.

“…However, only a single winding trajectory was simulated, rather than a path showing the width of the yarn. Several works of the literature (Hongya et al, 2007;Xianfeng et al, 2010;Zu et al, 2012) used a similar approach to simulate the winding process for other mandrel shapes, such as toroidal tanks, S-elbows, aircraft inlets, and vanes. Nonetheless, they were not real filament winding simulations because no consideration was given to the cross-section shape of yarn in the model.…”

Computational Geometry-Based 3D Yarn Path Modeling of Wound SiCf/SiC-Cladding Tubes and Its Application to Meso-Scale Finite Element Model

The filament winding process is a competitive performing technology for nuclear fuel cladding tubes due to its high automation. The study of the yarn path on the mandrel surface is vital to design and produce the cladding tube with the desired mechanical properties, reducing manufacturing time and costs. The geodesic and semi-geodesic trajectories are used to create a 3D yarn path in this paper. A 3D yarn path optimization method based on the principle of minimum potential energy is proposed to simulate the overlap effect in accord with the real winding process. The finite element (FE) mesh based on the 3D yarn path has been used for the mechanical analysis of the cladding tube. The embedded region constraint is applied to define the interaction between the matrix mesh and the yarn mesh to model the meso-structure of the cladding tube. Based on the meso-scale FE model, the mechanical behavior of the wound SiCf/SiC nuclear fuel cladding tube is studied in detail. The results show that due to the neglect of the overlap effect, the conventional laminate model overestimates the cladding tube strength. The proposed meso-scale FE model can accurately predict the failure of the cladding tube. The results also confirm that the creation of a 3D yarn path and the derived meso-scale FE model, representing an accurate wound structure, are of importance to the prediction of the performance of the cladding tube.
