Abstract
A method for depositing a coating on a continuous carbon or ceramic fiber from a precursor of the coating, the method including at least the heating of at least one segment of the fiber in the presence of a liquid or supercritical phase of the coating precursor by a laser beam so as to bring the surface of the segment to a temperature allowing the formation of the coating on the segment from the coating precursor.
Claims13
A method for depositing a coating on a continuous carbon or ceramic fiber from a precursor of the coating, the method being:
- (i) a calefaction deposition method comprising:
- heating at least one segment of the fiber in the presence of a liquid phase of the coating precursor by a laser beam so as to bring the surface of the segment to a temperature allowing the formation of the coating on the segment from the coating precursor;
- or
- (ii) a method comprising:
- heating at least one segment of the fiber in the presence of a supercritical phase of the coating precursor by a laser beam so as to bring the surface of the segment to a temperature allowing the formation of the coating on the segment from the coating precursor.
A device for implementing a method for depositing a coating on a continuous fiber from a precursor of the coating in the liquid phase, the device comprising a tubular reactor having a U-shaped section to contain the fiber and the precursor of the coating in the liquid phase, a laser source to generate a laser beam in the reactor intended to heat the surface of a segment of the fiber in the presence of the precursor of the coating in the liquid phase, and a device for making the fiber travel inside the reactor, the travel device comprises a first mandrel from which the fiber is configured to be unwound, and a second mandrel on which the coated fiber is configured to be wound.
