Abstract
A method for coating fibres includes coating short fibres having an average length less than or equal to 5 mm by chemical vapour deposition in a fluidised bed, the short fibres treated being made of ceramic material or carbon and being mixed with spacer particles distinct from the short fibres, the spacer particles having an average diameter greater than or equal to 20 μm.

A method for coating fibres, comprising:
- coating short fibres having an average length less than or equal to 5 mm by chemical vapour deposition in a fluidised bed, the short fibres treated being made of ceramic material or carbon and being mixed with spacer particles distinct from the short fibres, said spacer particles having an average diameter greater than or equal to 20 μm, the spacer particles belonging to Geldart groupings A or B and the content by volume of spacer particles in the mixture with the short fibres being between 25% and 95%.
