1. A method for coating fibers, comprising:
desizing sized short fibers by removing a sizing present on the short fibers, the short fibers having an average length less than or equal to 5 mm, the short fibers being made of ceramic material or carbon,
sieving the desized short fibers in order to separate them from any agglomerates of sized short fibers still present,
introducing the desized and sieved short fibers into a reactor, and
coating the short fibers in the reactor by chemical vapor deposition in a fluidized bed.
