"E_SLEEVE activities deal with the design, set-up and demonstration of two distinct processes for the filament winding of the required carbon composite retaining sleeve, to be realized directly integrated onto the high speed motocompressor rotor of air conditioning systems used in aircraft application: the first one will use Cyanate Ester resin and subsequent bulk curing, the second one will use 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 will be validated by manufacturing the required five sleeves directly on the rotor sub-assembly. Next Technology Tecnotessile has 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, will be involved to advice on resin formulation and provide support to process design and set-up and to validation activities. Further industrial up-scaling scenarios with cost analysis will be produced for both processes and full collaboration with Topic Manager on exploitation and dissemination activities will be provided."
