Description

COMPOSITE COMPONENT MANUFACTURE
Field of the Invention
The present invention relates to a method and apparatus for making a composite component. In particular, the present invention relates to a method and apparatus for making a composite component (e.g. an aerofoil blade or vane for a gas turbine engine) using a liquid moulding process.
Background of the Invention
Composite components such as an aerofoil blade or vane for a gas turbine engine have a fibrous network embedded within a matrix material e.g. a thermoplastic material or a metal.
Such a composite component is typically formed by moulding liquid/molten matrix material around a fibrous preform and then either curing or cooling the liquid/molten matrix material to harden it.
In a known resin transfer moulding process, the fibrous preform (which is typically formed of fibre tows each comprising a number of filaments) is positioned within a mould cavity. Liquid matrix material is introduced at an inlet of the mould cavity and forced under pressure through the fibrous preform to an outlet. Once the matrix material has permeated the fibrous preform and filled the mould cavity, the liquid matrix material is hardened around the fibrous e.g. by curing in the case of a thermoplastic matrix material.
This method inevitably exhibits a pressure drop through the mould cavity from the inlet to the outlet. The larger the mould cavity, the larger the pressure drop through the mould. The pressure drop is the result of the fibrous preform impeding the flow of the liquid matrix material through the mould cavity. This impedance is increased by the fact that the fibre tows are often compressed when forming the fibrous network preform in order to maximise the fibre volume fraction within the resulting component. This compression reduces the permeability of the fibrous preform even further.
As a result of this pressure drop through the mould cavity, porosity of the matrix material in the composite component tends to increase in locations formed under lower pressure.
Increased porosity is undesirable since it compromises component durability and quality. In these locations formed under lower pressure, it is also observed that the matrix material can fail to completely permeate the fibre tows forming the fibrous preform i.e. there is insufficient pressure to force the liquid matrix material between the filaments in the fibre tows. Yet another problem is that large pressure differentials between the inlet and outlet of the mould cavity can lead to disruption of the fibres within the preform resulting in fibre distortions, uneven fibre concentrations and even fibre creasing or folding.
To try and counter these problems, it is known to apply a partial vacuum to the mould cavity to help pull the liquid matrix material through the mould cavity. It is also known to provide multiple inlets and outlets to try and minimise the flow path of the liquid matrix material through the mould cavity. Yet another attempt to address the problem discussed above is to provide an adjustable mould cavity that is filled with liquid matrix material (around the fibrous preform) and subsequently compressed. This requires the mould cavity to be formed of material which does not distort under mechanical pressure.
The present invention aims to provide a method for forming a composite component where porosity of the matrix material is reduced and permeation of the filaments in the fibre tows forming the fibrous preform by the matrix material is increased even in locations formed under lower pressure.
Summary of the Invention
In a first aspect, the present invention provides a method of manufacturing a composite component comprising a fibrous network and a matrix material, the method comprising: providing a fibrous preform within a cavity of a mould; and filling the mould cavity with a liquid/molten matrix material, wherein the method further comprises vibrating the mould.
In a second aspect, the present invention provides an apparatus for manufacturing a composite component comprising a fibrous network and a matrix material, the apparatus comprising a mould having a cavity for receiving a fibrous preform and liquid/molten matrix material, wherein the apparatus further comprises one or more vibrators for vibrating the mould.
By vibrating the mould during and/or after the filling of the mould cavity with the liquid/molten matrix material, it has been found that porosity of the matrix material in the resulting composite component can be reduced and the permeation of the fibre tows in the fibrous preform by the liquid/molten matrix material can be increased. As a result, it has been found that a lower inlet pressure can be used. This reduces any disruption of the fibres in the fibrous preform and also leads to a lower pressure gradient between the inlet and outlet which, in turn, reduces pore formation. It has also been found that vibration allows for use of a liquid/molten matrix material having a higher viscosity.
Optional features of the invention will now be set out. These are applicable singly or in any combination with any aspect of the invention.
The method may comprise vibrating the mould during filling of the mould cavity with the liquid/molten matrix material.
Vibrating the mould during filling of the mould cavity with the liquid/molten matrix material increases the permeability of the fibrous preform firstly by excitation of the fluid front of the liquid/molten matrix material which facilitates flow between the fibre tows of the fibrous preform and secondly by induction of oscillations within the fibre tows of the fibrous preform which allows increased permeation of the fibre tows by the liquid/molten matrix material.
Since the oscillations within the fibre tows will cease once they are permeated with the liquid/molten matrix material (because the matrix material will dampen the vibrations), measurement of the 0 factor can be used to determine the position of the fluid front of the liquid/molten matrix material. Another advantage of vibrating the mould during filling is that it dislodges air bubbles trapped the fibrous preform.
The method may comprise vibrating the mould after filing of the mould cavity with the liquid/molten matrix material. This vibration after filling may occur before and/or during hardening (e.g. by curing/cooling) of the liquid/molten matrix material.
Vibrating the mould after filling of the mould cavity with the liquid/molten matrix material acts to coalesce and dislodge any voids within the liquid/molten matrix material and/or to promote dissolution of gas bubbles into the liquid/molten matrix material.
The method may comprise vibrating the mould both during and after filling of the mould cavity with the liquid/molten matrix material.
The one or more vibrators may be adapted to vibrate at first frequency and at a second frequency. Alternatively, one of said one or more vibrators may be adapted to vibrate at the first frequency and one of said one or more vibrators may be adapted to vibrate at a second frequency. The second frequency may be higher than the first frequency. For example, the first frequency may be between 1 to 5 Hz and the second frequency may be between 5 and Hz. The method may comprise vibrating the mould at the first and second frequency.
The method may comprise vibrating the mould at the first frequency during filling of the mould cavity with the liquid/molten matrix material and at the second frequency after filling of the mould cavity with the liquid/molten matrix material.
The one or more vibrators may be adapted to vibrate at a first amplitude and a second amplitude. Alternatively, one of said one or more vibrators may be adapted to vibrate at the first amplitude and one of said one or more vibrators may be adapted to vibrate at a second amplitude. The second amplitude may be greater than the first amplitude. The second amplitude may be up to 40 mm. The method may comprise vibrating the mould at the first and second amplitude.
The one or more vibrators may be adapted to vibrate in a first direction and a second direction. For example, one of said one or more vibrators may be adapted to vibrate in a first direction and one of said one or more vibrators may be adapted to vibrate in s second direction. The first and second directions may be perpendicular to one another. The method may comprise vibrating the mould in the first and second directions. The method may comprise alternating between vibrating the mould in the first direction and the second direction.
The one or more vibrators may be adapted to provide zoned vibration i.e. to selectively vibrate portions of the mould. For example, there may be a plurality of mutually spaced, selectively vibratable vibrators. The method may comprise selectively vibrating a portion of the mould.
Zoned vibration allows control of the movement of the fluid front of the liquid/molten matrix material through the mould cavity. For example, the movement of the fluid front can be increased by vibration in selected portions and decreased by cessation of vibration in other portions.
The method may further comprise flushing the mould cavity with a matrix material-permeable gas or fluid prior to filling the mould cavity with the liquid/molten matrix material. Any bubbles of this gas/fluid will be absorbed into the liquid/molten matrix material during vibration of the mould.
The one or more vibrators may comprise one or more electro-mechanical vibrators and/or one or more ultrasonic vibrators. The method may comprise electro-mechanical and/or ultrasonic vibration of the mould.
The one or more vibrators may be affixed to or in abutment with an outer surface of the mould. The one or more vibrators may be at least partly or completely embedded within the mould. The one or more vibrators may at least partly or completely surround the mould.
The matrix material may be a thermoplastic material such as an epoxy resin (with the resulting component being formed of fibre reinforced plastic (FRP)). In this case, the method may be a resin transfer moulding method, a vacuum bag moulding method, a pressure bag moulding method or an autoclave moulding method.
The matrix material may be a metal e.g. titanium (with the resulting component being formed of a metal matrix composite (MMC).
When forming a MMC or in the case of autoclave moulding of an FRP, the method may comprise heating and/or applying pressure to the mould during vibration. Vibration allows a reduction in the pressure required and also reduces the length of time that heating is required.
The fibrous preform may be pre-impregnated with matrix material.
In a third aspect, the present invention provides a composite component e.g. an aerofoil blade or vane for a gas turbine engine, formed using the method of the first aspect or the apparatus of the second aspect.
Brief Description of the Drawings
Embodiments of the invention will now be described by way of example with reference to the accompanying drawings in which: Figure 1 shows an apparatus according to a first embodiment of the present invention.
Detailed Description and Further Optional Features of the Invention Figure 1 shows an apparatus 1 according to a first embodiment of the present invention.
The apparatus comprises a mould 2 having an upper part 3 and a lower part 4 which are clamped together by bolts 5 to define a mould cavity 6.
A fibrous preform 7 formed of fibre tows each made up a plurality of filaments is positioned within the mould cavity 6.
An electro-mechanical vibrator 8 is provided in abutment with an outer surface 9 of the lower part 4 of the mould 2. The vibrator 8 is mounted on springs 10 on a substrate 11 and side walls 12.
In use, a matrix-material gas is flushed through the mould cavity 6 to at least partly replace any air within the mould cavity 6.
Next, a liquid matrix material e.g. an epoxy resin in introduced under pressure into a number of inlets 13 in the upper part 3 of the mould 2.
Outlets 14 are provided in the lower part 4 of the mould 2 and these can be used to apply a vacuum to the mould cavity 6 to assist in the introduction of the epoxy resin.
As the liquid matrix material is introduced into the mould cavity 6, the vibrator 7 vibrates the mould 2 at a first frequency of 2Hz.
Vibrating the mould 2 during filling of the mould cavity 6 with the liquid/molten matrix material increases the permeability of the fibrous preform 7 firstly by excitation of the fluid front of the liquid/molten matrix material which facilitates flow between the fibre tows of the fibrous preform 7 and secondly by induction of oscillations within the fibre tows of the fibrous preform 7 which allows increased permeation of the fibre tows by the liquid/molten matrix material.
Vibration of the mould 2 during filling of the mould cavity 6 also dislodges any air bubbles trapped the fibrous preform 7 and causes any bubbles of the matrix-permeable gas to be dispersed within the liquid matrix material.
Once the mould cavity 6 is filled with the liquid matrix material, the vibrator 7 vibrates the mould at a second, higher frequency of 10Hz both before and during hardening (by curing) of the liquid matrix material.
Vibrating the mould 2 after filling of the mould cavity 6 with the liquid matrix material acts to coalesce and dislodge any voids within the liquid matrix material and to promote dissolution of the matrix material-permeable gas bubbles into the liquid matrix material.
Once the matrix material is hardened, the upper part 3 and lower part 4 of the mould 2 can be separated and the moulded component removed from the mould cavity 6 for further processing.
While the invention has been described in conjunction with the exemplary embodiments described above, many equivalent modifications and variations will be apparent to those skilled in the art when given this disclosure. Accordingly, the exemplary embodiments of the invention set forth above are considered to be illustrative and not limiting. Various changes to the described embodiments may be made without departing from the spirit and scope of the invention.
All references referred to above are hereby incorporated by reference.
