HIGH PERFORMANCE REINFORCED THERMOPLASTICS FOR AEROSPACE STRUCTURAL APPLICATIONS PROCESSED BY INJECTION MOULDING

Objective


Some industrial aeronautical parts have been successfully injection moulded using the knowledge and data provided by this programme. Mass and cost reduction are likely and this prices will be used increasingly in future aeronautical industries. Three industrial and complex parts were studied and manufactured by project partners.
One of the most cost-saving techniques for manufacturing certain aerospace structural parts will probably be in the near future the injection moulding technology. The use of such a process in the aerospace industry requires:
- increased mechanical properties of injection moulded parts;
- design data and tools to predict the properties which could be obtained with such a process.

The first point will be reached either by using aerospace high performance fibre reinforced thermoplastics, by increasing the fibre length in the mould or by using the Multi Live System which permits better control of the fibre orientation. Thus different processes will be developed and investigated in order to decrease the fibre degradation during the injection moulding phase.

The second requirement will be met by developing simulation software for filling and fibre orientation. Emphasis will especially be placed on weld line modelling and characterisation. The models and software will first be developed for short fibre high performance thermoplastics and then tested with the other processes.
