FEATURE “Aeronautics” Opinion Comparative costs for a fuselage skin panel made in thermoset composite or thermoplastic composite (tooling costs roughly the same for both) The above example is not necessarily an exact one, but the comparative magnitudes have been respected. This means that one should not make a decision based on the price of the raw materials, but always do a complete economic feasibility study. The savings here are due mainly to processing speed. Here again, we should note that long-fibre-reinforced thermoplastic composites are only just emerging and that their cost will decrease with economies of scale. Like the thermoplastics that replaced thermoset resins in the 1970s, thermoplastic composites will inevitably become the materials of choice in the near future, for technical and economic reasons, as shown by the table below: Types of resource g…/… Fully automated RTM production line We have known for nearly a decade how to make engineering thermoplastic composites using PPS, PEI, and PEEK plastics reinforced with long carbon fibres. Airbus designed part of the leading edge of its A380 aircraft in carbon/PPS, but declined to pursue this innovatory direction in spite of its promise. Engineering thermoplastic composites have the following advantages: - lower specific mass; - no chemical reaction or autoclave needed, giving a faster processing cycle that allows the use of lay-up, compression moulding, thermoforming, welding, pultrusion or filamentwinding techniques; - better impact resistance; - recyclability (while thermosets by their very nature are not reprocessable). There are a few disadvantages that can be overcome: - the basic semi-finished product used is more expensive, but economies of scale can bring the price down; - a need to change/adapt the manufacturing methods, but compensated for by cheaper investment; the major difficulty would be overcoming preconceived ideas and habits. All in all, the economic balance leans in favour of thermoplastic composites – and European prepreg manufacturers know how to make them.
