“…The calculation of a geodesic path on some mandrel surfaces is (locally) not possible and, therefore, the use of non-geodesic paths becomes necessary. Non-geodesic paths may also be used to increase the design freedom and for the optimization of the mechanical properties [19][20][21]. They make use of the friction force to avoid slippage of fibers from the mandrel surface [22].…”

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.

With the advantages of high specific strength and well corrosion resistance, polymer-matrix composite tee pipes are widely used in aerospace and civilian fields. The robotic filament winding technology is suitable for forming complex shape parts. This paper aims to provide a novel non-geodesic trajectory design method to get a continuous trajectory for tee pipe winding. Furthermore, post-processing methods are proposed for realizing the full coverage of tee pipes by robotic filament winding. The CAD/CAM software is then designed to simulate the winding process and realize the cover of the whole tee pipe. Finally, experiments of winding a tee pipe with a desktop winding machine and a six-axis winding robot are carried out. The results show that the tee pipe is fully covered, verifying the accuracy of the design method and post-processing methods.

“…However, this kind of method is suitable only for a mandrel whose surface can be described by mathematical equations. In order to realize the generation of filament winding paths without using mathematical expressions, Fu et al 16 considered the principal stress field of the axisymmetric model and generated a filament winding path on the surfaces of STL triangles. However, this method is suitable only for axisymmetric models and cannot be used to realize uniform pattern generation for non-axisymmetric models.…”

High-strength, continuous and uniform filament winding patterns remain challenging to find for non-axisymmetric models under various loading conditions. In this study, various loading conditions are considered in the development of an algorithm for generating uniform winding patterns for axisymmetric and non-axisymmetric mandrel models with flexible rotation at the ends of the mandrel. First, the mandrel surface is divided into sections by uniform quadrilateral elements and the ideal winding angle at each boundary is calculated based on the stress field. Then, stability analysis is used to calculate suitable winding angles as close as possible to the ideal winding angle for each boundary. These suitable winding angles can be used to generate the uniform winding pattern maintaining non-slippage and non-bridging while realizing flexible rotation at both ends of the mandrel. Finally, uniform patterns for various mandrel models are generated based on their respective suitable winding angles. Stress analysis result demonstrates that the wound mandrel generated by the proposed method can have better carrying capacity.
