What "wind angle" means
During filament winding, continuous fibre is laid onto a rotating mandrel by a moving carriage. The angle the fibre makes relative to the mandrel axis is the wind angle, and it dictates the direction in which the finished part is strongest. By coordinating mandrel rotation and carriage speed under CNC control, that angle is placed precisely and repeatably.
Low angles (~30°)
Fibre laid close to the axis carries axial, compressive and bending loads. Low-angle layups suit drive shafts, columns and structural tubes where the dominant loads run along the length of the part.
High angles (~85°)
Fibre laid nearly circumferentially carries hoop (burst) load. High-angle layups are what make a pressure vessel or a pneumatic cylinder hold pressure, the fibre resists the tube trying to split along its length.
Engineering the layup
Real parts rarely use a single angle. We build a layup schedule that combines angles to meet the actual load case, some plies for hoop strength, some for axial, some for torsion. This is the heart of why a direct manufacturer can serve an application a distributor cannot: the layup is engineered per part, not selected from a catalogue.
