European high temperature fibres

Objective

The recent development in Europe of fibre-reinforced ceramic materials based on Japanese reinforcements has demonstrated the feasibility of extending the temperature range provided by the high temperature materials currently used. The project will aim at providing European sources of high temperature filaments capable of operating air.

Three types of fibre have been identified:

a) a low cost fibre of less than 20 fm diam. for application to 1000 deg. C
b) a high performance fibre of less than 20 fm diam. for application to 1300 deg. C
c) a high performance fibre, for application to 1500 deg. C in air

The first two fibre types may fall into the same category. Precursor fibres which are pyrolysed to give small diameter (20 fm) polycrystalline or amorphous ceramic fibres represent the production route which provides the Japanese fibres at present used. It is proposed that this route should be explored for the production of the fibre types a and b above, but with the target to achieve fibres of higher E-modulus and strength. The requirements of the fibre type c may be achieved by continuous single crystal filaments with diameters of less than 50 fm. The feasibility of these materials and appropriate production routes should be investigated.

Definition Phase:
The Definition Phase will detail precisely the aim of the Research, Development and Exploitation Phase. To do this two working parties will established consisting of all the industrial partners and some academic specialists and co-ordinated by two firms having particular interest in one or more of the fibre types. These working parties will use their respective experiences with the currently available composites together with a scientific analysis of the high temperature potential of materials to define the characteristics required of the three types of fibre. The members of these working parties will also co-operate in a study of the market potential of these fibre types.

Based on this knowledge research teams will be chosen and defined to develop and characterise the required filaments and production routes.

The two working parties will combine to explore funding sources with the European countries involved.

At present a number of research teams have been identified in Europe who are capable of developing high temperature filaments either by the conversion of precursor fibres or by growing single crystal filaments. A number of large industrial users representing advanced European technology for whom the development of European sources of high temperature reinforcements is a strategic necessity, have come together to support this project. An important goal of the Definition Phase will be the identification and involvement of a firm or firms capable of manufacturing precursor fibres and converting them into ceramic filaments. If such a firm is not associated with the project to produce ceramic fibres from precursors, it will be deemed to fail and will not continue. In this event, the part of the project related to single crystal filaments for application above 1300 deg. C will require a new decision to be taken.
