Within the Clean Sky JTI, the use of a nanocomposite material for primary structures of a Green Regional Aircraft was thoroughly studied and analysed. The nano-filler modified matrix have a great potential to exhibit high performance in terms of thermal, mechanical and electrical properties. The modified resins should be able to be used in the prepreg route for composite fabrication, which means that the uncured resin must exhibits proper rheological properties and dispersion in liquid phase compatible with the impregnation of dry fibre fabrics.
The objective of AIT was to manufacture nanomodified resins to fulfil the requirements of the Clean Sky roadmap. In a first step, nanoparticles will be selected among 1D (needle shape like carbon nanotubes or nanofibres), 2D (plate shape like nanoclays) and 3D (ball shape like Al2O3, ZrO2, or Boehmite) geometries. Then AIT will benefit of its experience in nanotechnology to set-up the dispersion methods, to produce batches of modified resin (12 different types are planed), to set up the curing parameter, to produce samples and finally, to characterise them. The proposed test campaign will investigate the chemical, physical, morphological, rheological, thermal, mechanical and electrical properties. The dissemination and exploitation of the result will be assure by the management Team in close communication and collaboration with the ITD leaders and other CS-RTD partners.
