Definitions
- the present invention relates to the general field of processes for depositing a coating on fibers, and more particularly on a continuous carbon or ceramic fiber from a precursor coating.
- the invention also relates to a device adapted to the implementation of such a method.
- Ceramic matrix composite (CMC) materials known for their good mechanical properties that make them suitable for forming structural elements and for retaining these properties at high temperatures, are a viable alternative to traditional metal parts. Their reduced mass compared to their metallic equivalent make them the best choice to answer the problems of increase of the yield and reduction of the polluting emissions of the engines in the aeronautical field.
- the CMC material parts comprise a generally continuous fibrous reinforcement in the form of a woven fabric, which is densified by a ceramic matrix.
- the fibrous reinforcement thus comprises continuous fibers, generally grouped together in the form of yarns or strands, the orientation of which can be adapted to the principal directions of stressing of the part during its use.
- the preform for forming the fibrous reinforcement may be woven from the continuous fiber strands to the dimensions of the workpiece (for example by two-dimensional or three-dimensional weaving), using a suitable loom.
- To produce a piece of CMC material which has improved mechanical properties it is known to have fibers in the fiber preform which are coated with an interphase, prior to densification of the preform.
- the main object of the present invention is thus to overcome such drawbacks by proposing a process for depositing a coating on a continuous carbon or ceramic fiber from a precursor of the coating, the process comprising at least 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 permitting formation of the coating on the segment from the coating precursor.
- a “fiber segment” here corresponds to a certain length of fiber, in other words, the segment extends along the length or the largest dimension of the fiber.
- a fiber segment is thus a portion of the non-zero length fiber.
- a fiber which may comprise a plurality of filaments a fiber segment may comprise a plurality of filaments.
- segment area refers to the area of each filament that makes up the fiber segment, if any.
- depositing or forming a coating on the fiber segment, depositing or forming the coating on the surface of each filament that composes the fiber segment, if any.
- the method according to the invention is remarkable in particular by the fact that a segment of the fiber is heated directly and locally with the aid of a laser beam.
- This local heating of the fiber makes it possible to reduce the energy consumption of the entire process compared to chemical vapor infiltration type processes in an enclosure whose walls are heated.
- the local laser heating also makes it possible to significantly increase the reproducibility of the process, the kinetics of the formation of the coating and its homogeneity.
- the method also makes it possible to reduce the amount of precursor required since it is only necessary for the heated fiber segment to be in the presence of the precursor in the liquid or supercritical phase.
- the method according to the invention is advantageous in that it is possible to choose the properties or characteristics of the laser beam, in particular its shape, its wavelength or its power, in order to further improve the kinetics of deposition and the adapt to the material of the fiber and / or the precursor.
- the shape of the beam may for example be chosen to focus the energy on a larger or smaller segment of the fiber.
- the wavelength of the laser beam may, for example, be chosen as a function of a maximum absorption wavelength of the material of the fiber.
- the wavelength of the laser beam may for example be chosen as a function of an activation wavelength of the precursor in the liquid or supercritical state, that is to say a wavelength where the precursor absorbs energy from the laser beam, thus facilitating the formation of the coating.
- the laser beam can be continuous or pulsed at a certain pulse frequency.
- the local heating by laser makes it possible to control the temperature conditions at the level of the fiber segment, and to pass for example the precursor to the supercritical state only in the vicinity of the fiber segment concerned.
- the heating with a laser beam can be used alone or in addition to traditional heating means.
- the method may further comprise the movement of the fiber in front of the laser beam so as to form the coating on several successive fiber segments.
- the scrolling of the fiber can be carried out continuously or semi-continuously, depending on the deposit kinetics inherent in the variants described above as well as the precursors involved. This arrangement makes it possible to carry out the deposit continuously. which makes the process easy to implement.
- several distinct fiber segments can be heated simultaneously by a plurality of laser beams.
- laser beams having different characteristics, for example to favor the absorption of the beam by the fiber and / or the activation of the precursor, and this at different locations of the fiber.
- This arrangement makes it possible to perform the deposition at several locations of the fiber simultaneously, which increases the kinetics of the deposit and can allow a faster scrolling of the fiber, if necessary. It is also possible to make temperature gradients along the fiber to control the properties of the coating as its crystallinity.
- a segment of the fiber may be heated by a plurality of laser beams distributed angularly around said segment. This arrangement makes it possible to further improve the homogeneity and the kinetics of the deposit on the fiber by ensuring uniform and uniform heating over the entire surface of the heated fiber segment.
- the coating may be an interphase coating.
- the fiber coated with an interphase can then be used for the manufacture of a piece of CMC material, for example by weaving (two-dimensional or three-dimensional weaving for example) to obtain a preform which will then be densified at least partially by a ceramic matrix such as silicon carbide.
- the interphase has a function of defragilating the composite material which favors the deflection of possible cracks reaching the interphase after having propagated in the matrix, preventing or delaying the breaking of fibers by such cracks. This interphase also makes it possible to protect the fiber of the matrix material during its formation.
- the coating may comprise a material chosen from the following: silicon carbides (SiC), pyrocarbon (PyC), doped or non-doped boron nitrides (BN, BN (Si)), doped or non-doped silicon nitrides (SiN, Si 3 N 4 , Si x N y O z ), boron carbides (B 4 C, BC), and mixtures thereof.
- the fiber may be silicon carbide.
- the material of the silicon carbide fiber may have an oxygen content of less than or equal to 1% atomic percentage.
- such a fiber may be a type Hi-Nicalon type fiber marketed by the Japanese company NGS.
- the invention also aims, according to a second aspect, a device for implementing a method for depositing a coating on a fiber continuous from a precursor of the liquid-phase coating, the device comprising a tubular reactor having a U-shaped section for containing the fiber and the precursor of the liquid-phase coating, a laser source for generating a laser beam in the reactor for heating 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 scrolling the fiber inside the reactor.
- the U-shape of the reactor section allows it to contain the coating precursor in the liquid state while ensuring good immersion of the fiber in the coating precursor.
- the device is advantageously adapted to deposit the coating on the fiber in a continuous manner using the scroll device.
- the scroll device may comprise a first mandrel from which the fiber is to be unwound, and a second mandrel on which the coated fiber is intended to be wound.
- the laser source may be configured to generate at least two laser beams at two distinct locations in the reactor.
- the device may comprise at least two laser sources configured to respectively generate at least two laser beams at two distinct locations in the reactor.
- the device may comprise several laser sources angularly distributed around the reactor to generate laser beams interfering inside the reactor.
