E_SLEEVE activities dealt with the design, set-up and demonstration of two distinct processes for the filament winding of the required carbon composite retaining sleeve, to be realised directly integrated onto the high speed motocompressor rotor of air conditioning systems used in aircraft application.
The first one used Cyanate Ester resin and subsequent bulk curing, the second one used specific resins for high temperature use and for direct layer-by-layer curing to be performed via low energy Electron beam, simultaneously to the filament winding process itself.
Each process was validated by manufacturing the required five sleeves directly on the rotor sub-assembly.
Next Technology Tecnotessile had internal expertise and equipment from previous projects and commissions allowing to fulfil the Topic expectations. Two European-level experts in layer-by-layer E-beam curing for aerospace applications were involved to advise on resin formulation and provide support to process design and set-up and to validation activities. Further industrial up-scaling scenarios with cost analysis were produced for both processes and full collaboration with Topic Manager on exploitation and dissemination activities was provided.
The E-SLEEVE project has dealt with the design, set-up and demonstration of two distinct processes for the filament winding of carbon composite retaining sleeves, to be realized directly integrated onto the electric rotor of high speed motocompressors for air conditioning systems used in aircraft applications: the first process uses cyanate ester resin and subsequent bulk curing, the second one uses an epoxy resin specifically formulated for high temperature and for direct layer-by-layer curing to be performed via low energy Electron Beam, simultaneously to the filament winding process itself. Both processes need to provide the necessary radial pressure to ensure safe retainment of the rotor magnets at high revolution speed.
Next Technology Tecnotessile has deployed internal and external specific expertise and equipment, and reached stable conditions in manufacturing sleeves on mandrels and rotors via the new filament finding process improved to reach high winding tension, and developed and tested new E-beam curable resins with high Tg. Further industrial up-scaling scenarios with cost analyses have been produced for full exploitation of results in both processes.
