Definitions
- the present invention relates to a substrate coated on an outer surface with an erosion protection layer.
- Erosion caused by particles such as dust, sand, snow, rain, hail, or salt can lead to a change in the surface condition, or even the geometry of a substrate. This erosion can also lead to a degradation of the structural behavior of the substrate.
- the erosion by the particles can lead to a modification of the surface state at their leading edge, negatively impacting the aerodynamic properties of the blade.
- Other elements may be negatively affected by erosion, such as paint compositions intended to coat industrial equipment or buildings.
- the invention relates to a substrate coated on an external surface by an erosion protection layer, said protective layer comprising a resin in which fibers having an average length of between 50 ⁇ m and 500 are dispersed. pm.
- the use of fibers having a particular average length of between 50 ⁇ m and 500 ⁇ m advantageously makes it possible to impart improved erosion resistance to the substrate.
- the fibers having such a length allow the creation of a network within the protective layer retaining the damaged elements following the impact with the particles responsible for erosion. When the fibers have an average length of less than 50 ⁇ m or greater than 500 ⁇ m, the network created does not make it possible to improve the resistance to erosion satisfactorily.
- the average length of the fibers is between 80 ⁇ m and 150 ⁇ m.

- the outer surface 6 of the substrate 1 is intended to be exposed to a flow of particles responsible for an erosion phenomenon, for example drops of water or solid particles.
- the substrate 1 may be of composite material and comprise a fiber reinforcement densified by a matrix.
- the matrix may be an organic matrix, such as an epoxy resin.
- the fiber reinforcement may comprise reinforcing fibers made of glass or carbon, or a mixture of such reinforcing fibers.
- the substrate 1 may be metallic, for example aluminum alloy.
- the protective layer 3 comprises a resin 5 in which fibers 7 having an average length of between 50 ⁇ m and 500 ⁇ m are dispersed.
- the term "average length" refers to the length given by the statistical distribution to half of the population (size D50).
- the average length of the fibers may be between 80 ⁇ m and 150 ⁇ m.
- the average diameter of the fibers may be less than or equal to 50 ⁇ m.
- the diameter of a fiber is its largest transverse dimension.
- mean diameter refers to the diameter given by the statistical distribution to half of the population.
- the fibers 7 can be chosen from: carbon fibers, glass fibers, silica fibers, basalt fibers, fibers of natural origin, such as flax fibers, and mixtures thereof.
- the fibers 7 may be carbon fibers.
- the resin 5 may be a polyurethane resin.
- the resin 5 may be an epoxy resin.
- the protective layer 3 can be formed by dispersing the fibers 7 in a paint composition.
- the protective layer 3 may consist essentially of a paint composition comprising the fibers 7.
- An example of a paint composition that may be used in the context of the invention is the paint marketed under the reference “RELEST® Wind HS”. Topcoat RAL 7035 "by BASF.
- the fibers 7 may be present in the protective layer 3 in a mass content greater than or equal to 0.1%, for example greater than or equal to 2.5%, for example greater than or equal to 5%.
- the fibers 7 may for example be present in the protective layer 3 in a mass content of between 0.1% and 30%, for example between 0.1% and 10%.
- the fibers 7 may for example be present in the protective layer 3 in a mass content of between 2.5% and 25%, for example between 2.5% and 10%, and even between 5% and 10%.
- the thickness e of the protective layer 3 may be greater than or equal to 50 ⁇ m, for example to 100 ⁇ m.
- FIG. 2 shows an exemplary embodiment in which the outer surface 6 of the substrate 1 has been coated with several protective layers 3a and 3b loaded by the fibers 7.
- the characteristics of the protective layer 3 described in connection with the Figure 1 apply to each of the protective layers 3a and 3b.
- the protective layer 3b may be in contact with the protective layer 3a.
- the protective layer 3b may be identical or different from the protective layer 3a.
- the outer layer of the coating covering the substrate 1 is formed by a layer 3 or 3b loaded with fibers 7 with an average length of between 50 ⁇ m and 500 ⁇ m. pm.
- a layer 3 or 3b loaded with fibers 7 with an average length of between 50 ⁇ m and 500 ⁇ m. pm.
- the outer layer 4 of the coating covering the substrate 1 is not loaded by the fibers 7.
- the outer layer 4 may be a paint layer.
- the outer layer 4 can provide an anti-erosion function or an aesthetic function.
- the characteristics of the protective layer 3 described in connection with FIG. 1 apply to the protective layer 3a of the example of FIG. 3.
- the outer layer 4 may be in contact with the protective layer 3.
- FIG. 4 shows an example in which the coated substrate 10 has an aerodynamic profile and here constitutes a wind turbine blade 10.
- the protective layer 3 covers in particular the leading edge of the substrate 10.
- the thickness of the protective layer 3 has been deliberately increased in FIG. 4 for reasons of readability.
- the substrate 10 constitutes a rotating part, that is to say a part intended to be rotated.
- the coated substrate may be a moving part such as a blade, an aircraft wing or an aircraft fuselage.
- the substrate may be a fixed part such as the surface exposed to the external environment of an industrial equipment or a building.
- Figures 5A, 5B, 5C and 5D show the coating state at 0, 30, 60 and 90 minutes, respectively.
- the coating begins to be damaged after 60 minutes (Figure 5C). Following this damage, erosion is then rapid. It is found that the coating is completely eroded after 90 minutes ( Figure 5D).
- FIGS. 6A to 6F A test according to the invention was carried out for which the results are provided in FIGS. 6A to 6F.
- the carbon fibers previously cut to an average length of 120 ⁇ m were dispersed in the paint marketed under the reference "RELEST® Wind HS Topcoat RAL 7035" by the company BASF.
- the average diameter of the fibers used was 7 ⁇ m.
- This composition was then applied to a substrate so as to form a coating having a thickness of about 150 ⁇ m.
- the coating formed had a carbon content of 10% by mass.
- Figures 6A, 6B, 6C, 6D, 6E and 6F show the condition of the coating respectively at 0, 30, 60, 90, 120 and 150 minutes.
- the presence of fibers in the protective layer modifies the degradation mode and improves the erosion resistance.
- the surface condition of the protective layer is changed rather than eroded.
- the appearance of a piercing of the protective layer is pushed back in time.
- the first local breakthrough of the protective layer is only obtained after 150 minutes of testing (FIG. 6F).
- the protective layer is not completely eroded but only locally pierced unlike the test outside the invention according to Example 1, where complete erosion was obtained as early as 90 minutes. .
- Example 2 This test was identical to that of Example 2 except that the coating formed had a mass content of 2.5% carbon fiber.
- Figures 7A, 7B, 7C and 7D show the coating state at 0, 30, 60 and 90 minutes, respectively.
- Example 3 has a better resistance to erosion than that of Example 1. It is in fact simply obtained at after 90 minutes of testing a local drilling and no longer a complete erosion as in the test outside the invention according to Example 1.
