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.
