Fabrication of Carbon Fibre Reinforced Thermoplastics Polycarbonate and Polysulfone
In recent years the market for advanced composite preparation was oversupplied by thermoplastics as a new group of matrix systems.1–4 Within these polymers polycarbonate PC and polysulfone PSU seem to be most suitable for carbon fibre reinforced thermoplastics at cryogenic temperature application because of their highest tensile strains up to 4.2 K.5 In this temperature range sufficient adhesion between carbon fibre and thermoplastic matrix is only achieved if the contamination of the active carbon fibre surface by water adsorption is hindered. A preparation method is presented that offers the possibility to form composites with thermoplastics PC and PSU by prepreg technique. Controlling quality parameters like pressure and press temperature are discussed with respect to the properties of the carbon fibre reinforced thermoplastic composites.
