Summary | Versatility of oxide fibre produced by the internal crystallization method (ICM)1 can be greatly enhanced by applying various coatings on the fibre to control the fibre/matrix interface in composites. Since various matrices need to interact with the fibre in various ways, a variety of the necessary coatings range from pure metals, such as molybdenum, to complex oxides, such as magnetoplumbites is necessary to satisfy requirements of composite technology. Hence, a variety of the coating methods should be used including CVD, sol-gel, etc. A peculiarity of the ICM-fibres is that they do not exist as continuous filaments, so the methods developed for continuous fibres are not directly suitable for ICM-fibres. Technical modifications of the known methods adjusting them to fibres bound into a carcass shall be described in the present paper. Also microstructure and some properties of the coatings are to be presented. |
