Ziel
The aim of the project is the development of advanced fib re reinforced high performance thermoplastics (e.g. PPS, PEEK) and in particular the development of appropriate processing techniques of 'large' organic sheets, prepregs, ribbons and foils. The program envisages the following aspects: Surface treatment of short and long carbon fibres Processing techniques for aligned short and long fibre reinforced sheets, prepregs, ribbons and foils. Cutting and bonding techniques. Winding techniques. The studies are expected to permit the use of such reinforced thermoplastics in aerospace components and to increase the potential range of their application in other industrial sectors.
The aim of the project is the development of advanced fibre reinforced high performance thermoplastics (eg poly p-phenylene sulphide (PPS), polyether ether ketone (PEEK)) and in particular the development of appropriate processing techniques of large organic sheets, prepregs, ribbons and foils. The program envisaged the following aspects of surface treatment of carbon fibres and the reaction on the mechanical properties, melt impregnation of thermoplastics prepregs, cutting and bonding techniques for thermoplastic prepregs, winding techniques, press and autoclave techniques and endless section production techniques. The studies are expected to permit the use of such reinforced thermoplastics in aerospace components and to increase the potential range of their application in other industrial sectors.
An investigation of fibre finishes to evaluate the influence on the mechanical properties of composites was carried out. A melt impregnation plant for thermoplastic prepregs was installed and is in operation. Press and autoclave techniques with several layups, tool materials and process parameters were examined and the techniques were optimised. Winding techniques with cold and heated mandrels were evaluated and 2 fully automatic endless section production tools for L-stringers and U-stringers were installed and are in operation.
THE PROGRAMME ENVISAGES THE FOLLOWING ASPECTS:
- SURFACE TREATMENTS OF SHORT AND LONG CARBON FIBRES.
- PROCESSING TECHNIQUES FOR ALIGNED SHORT AND LONG FIBRE REINFORCED SHEETS, PREPREGS, RIBBONS AND FOILS.
- CUTTING AND BONDING TECHNIQUES.
- WINDING TECHNIQUES.
