| Résumé : |
In the framework of the French national DPAC COMP TP (Thermoplastic) Program, EADS IW has continued its long term efforts on the development of thermoplastic composites technologies for aeronautics structural applications. Most of the research and development activities were focused on the manufacture of "nase" fuselage parts, such as skin panels and stringers and (or) frames, and on the development of TP welding processes. Aircraft windshield front fairings were estimated as good candidates for thermoplastics technologies among all the aeronautic nase fuselage parts. Therefore this paper will discuss the recent developments led by EADS IW, for manufacturing a technological demonstrator, whose main specifications are:
- Thick part (compared to fuselage skins thicknesses) for potential impact resistance properties
- Geometry with severe double curvatures
- Use of cost-effective manufacturing processes
These specifications led to a development program that encompassed the following activities:
- Determination and validation of process limits for TP parts consolidation in aven.
- Automated lay down technique for TP multi-tows deposition with a laser heating system.
- Panel metallization, for LSP application, with a laser TP tape deposition machine.
- Press-forming process for manufacture of thick and double curvature stiffeners.
- Specific welding process and understanding the mixing of different high performance thermoplastic materials.
A specific design of a representative Thermoplastic CFRC Panel has been created and the associated technological demonstrator is manufactured for validation of the different related development works. Mechanical performance, detailed structural sizing and actual impact resistance of such a component will be addressed at a later date in another development program. |
