METHOD FOR THE PRODUCTION OF A FIBRE-REINFORCED CARBON-CERAMIC COMPOSITE MATERIAL, COMPOSITE CARBON-CERAMIC MATERIAL OBTAINED USING SUCH METHOD AND COMPONENT OF A DISC BRAKE MADE OF SUCH MATERIAL

摘要

The invention relates to a method for the production of a composite, fibre-reinforced carbon-ceramic material comprising at least the following operating steps: a) preparing a mixture comprising at least reinforcing fibres and an organic agglomerating binder; b) forming the mixture to obtain a semi-finished product; c) infiltrating the semi-finished product with molten silicon, subjecting the semi-finished product to a firing in the presence of silicon at a temperature such as substantially to bring about the fusion of said silicon and its infiltration into said semi-finished product thus obtaining a composite, fibre-reinforced carbon-ceramic material. The organic agglomerating binder, essential for the forming of such material, is present between 15% and 25% by weight of said mixture and comprises cellulose, methyl cellulose or a mixture of cellulose and methyl cellulose and is added to said mixture together with water. The forming step is conducted at a temperature not exceeding 100°C.
