Summary on Grant Application Form |
|
It is proposed to develop a low-cost powder metallurgy technique, via. tape-casting, for the manufacture of titanium based continuous SiC fibre composites, in close collaboration with British companies. The process involves the casting of a powder/fibre slurry into a thin powder tape. Fibres are either introduced concurrently or subsequently to form a powder/fibre pre-form, which is then consolidated at temperature into a composite. The process uses low-cost facilities, large inexpensive powder and short consolidation time, with low energy consumption, high flexibility, reduced interfacial reaction and fibre damage. The low-cost materials can lead to enhanced aero-engine performance and fuel efficiency, so reducing environmental impact. The programme mainly concentrates on two key stages 1) binder burn-out and 2) consolidation. The burn-out mechanisms and kinetics of selected binders will be systematically investigated by both experimental techniques, such as TGA, Mass Spectrometry, FR-IR/FT-Raman and electron microscopy and theoretical modelling of the decomposition, diffusion and evaporation processes involved. Powder/fibre consolidation will be carried out under similar conditions to those used in Foil-Fibre-Foil lay-ups. Micromechanical modelling of the consolidation process will be conducted to optimise the conditions and to minimise undesirable interfacial reaction and fibre damage. High-quality composites will be produced in the end.
