The Project HIGHPSLEEVE aimed to find out a way to produce a fixation component for an electrical motor, which turns at 50.000 RPM and works in -50 to 250ºC, of an aircraft by using composites materials with high Tg, such as BMI or Cyanate ester, reinforced with carbon fibres. Production method need to be researched but Filament Winding seems to be the right candidate process. In particular the design and manufacturing of sleeve component was targeted. The project looked for a cost-effective way of producing these fixation components in these composites material while ensuring to withstand with requirements. The aim was to get a cost effective way of manufacturing.
