One of the most important parts of the filament winding process is, of course, pattern also described as orientations of the placed fibres. Since orientation affects the mechanical properties, optimum fibre orientation must be selected for effective manufacturing.
Creating the appropriate pattern provide minimized thickness and optimum properties which also significantly gives an advantage for the material cost.
Fiber Orientations are Significant
Ensuring the optimum fiber orientation generally requires proper analysis and algorithm. This can require either a finite element analysis and experience with composite materials. When requirements of properties and dimensions are known, the optimum orientation of the fibres on the mandrel becomes crucial.
Creating the Pattern
When it comes to creating patterns with the desired orientations, algorithms or commercial software can be used. In both ways, the fundamental theory is the same that fibres must be oriented by considering the parameters, such as width, slippage, thickness and angle.
