Most filament winding machines now have computer controls and at least three axes. Winding with four axes is increasingly common because the shapes of the products have evolved to include more complexity. The automation used on the winding machine and ancillary components does not eliminate the need for proper fiber handling. This chapter is a primer on modern filament winding equipment and its use, starting with an overview of machine control and then discussing the design and structural analysis of filament wound components such as pressure vessels, pipes, grid structures, deep sea oil platform drill risers, high-speed rotors, and filament-wound preforms.
