This research investigates the optimization of filament winding pre-stress for Carbon Fiber Reinforced Polymer (CFRP) retaining sleeves used in high-speed Permanent Magnet Synchronous Motors (PMSM). The study utilized numerical simulations in ANSYS Workbench to define load parameters, followed by the manufacturing and destructive tensile testing of 11 composite specimens with winding tensions ranging from 5 to 30 kg. Using Digital Image Correlation (DIC) for analysis, the results demonstrated that optimal pre-stress significantly improves manufacturing repeatability. While average tensile strength increased marginally (4%), the statistical deviation was reduced to approximately one-third of the original range, establishing a reliable strength limit within a 95% confidence interval.
