Definitions
- the present patent application relates to a method of non-destructive testing (CND in the following) of an organic matrix composite material.
- Such a material may be used in particular in the field of aeronautics, and more particularly inside a propulsion unit comprising a nacelle and, inside thereof, a turbojet engine.
- CMO organic matrix composite material
- IFS also vein of cold air
- Such an IFS is subjected to very high temperatures on the turbojet side, which can eventually lead to degradation of the CMO by physico-chemical aging.
- the present invention thus aims in particular to provide a very reliable and simple process to implement, to non-destructively control a CMO part that can be used in particular within an aircraft propulsion system.
- a) carry out a control of this part by Fourier Transform Infrared Spectroscopy (FTIR), b) if step a) reveals a defect, carry out depth checks of said material using two techniques. complementary ultrasound.
- FTIR Fourier Transform Infrared Spectroscopy
- step a) an average of several FTIR spectra carried out in the zone under study is carried out, and step b) is carried out when the analysis of the peaks characteristic of physico-chemical aging exceeds minus a predetermined threshold of non-compliance, taking into account the paint thickness measurement when the part is painted;
- step b) the results of the measurements given by each ultrasound technique are collected, and it is decided in favor of a need for repair of the part when at least one of these results exceeds at least one predetermined threshold of non-compliance; such a threshold is defined from decision support truth tables, themselves constructed during developmental trials;
- one of the two ultrasonic techniques consists of a measurement of acoustic energy transmitted by surface waves on the studied area, and the other of the two ultrasonic techniques consists of measuring the electromechanical impedance of said zone of the material;
- said ultrasonic measurements are carried out after a normalization step of said zone: this normalization step makes it possible to carry out a calibration of the measurements;
- step b stripping of the paint covering the surface of said part is carried out: this step, applicable only when the part to be inspected is coated with paint, is necessary to implement the ultrasonic measurements of the step b);
- the present invention is intended in particular for the CND of an aircraft propulsion unit part such as a fixed internal structure (IFS) of an aircraft turbojet engine nacelle.
- IFS fixed internal structure
- this part 1 is an IFS, that is to say a part intended to streamline the turbojet engine of an aircraft, having on its internal face, that is to say on its face intended to be vis-à-vis the turbojet engine, a thermal insulation mattress 3.
- the thermal insulation mat 3 has been partially torn off, thus exposing the composite material forming this ISF.
- this composite material is an organic matrix composite (CMO), that is to say a composite material formed of a stack of plies, each obtained by polymerization of an organic resin (resin of type BN I for example), this resin trapping fibers for example carbon.
- CMO organic matrix composite
- the zone 5 in which the thermal mat 3 has been partially torn off is the area of the CMO material that is to be controlled.
- this material is subjected to very high temperatures, likely to cause defects such as degradation of the CMO by physico-chemical aging, and it is important to periodically control aging.
- the zone 5 is cleaned with a dry cloth (step 7) so as to remove grease and other polluting particles.
- a conventional CND (step 9), typically comprising a stickiness control, is then performed with a Olympus Bondmaster (a special ultrasonic device from Olympus) and a Tap Test, ie a acoustic hammer test, to detect any areas of takeoff CMO.
- Olympus Bondmaster a special ultrasonic device from Olympus
- a Tap Test ie a acoustic hammer test
- step 11 If the CND of step 9 is positive, the extent of the defective zone is determined in step 11.
- step 9 If the conventional tests carried out in step 9 do not make it possible to demonstrate a CMO maneuver detachment, then one goes to step 1 5, in which a surface control of the zone 5 of the CMO is carried out, using a Fourier transform infrared spectroscopy (FTIR) apparatus.
- FTIR Fourier transform infrared spectroscopy
- This portable device is in the form of a gun that is swept on the zone 5.
- This device can measure, on surfaces of the order of 2mm x 2mm, the absorbance of infrared rays over a wavelength range of 4000 to 500 cm -1 .
- va ri a tio ns of a bso rba n ce of the radii are indicative of surface defects in the CMO.
- step 1 7 When the analysis of the peaks characteristic of physicochemical aging (determined by the development tests) remains below a threshold of nonconformity NC1 (step 1 7), by means of coherence with the measurement of paint attenuator When the part is painted, it is considered that the CMO does not have a surface defect, and that it is therefore not necessary to carry out further investigations: the conclusion is that the IFS is fit for flight ( step 18).
- this predetermined threshold NC1 When, on the other hand, this predetermined threshold NC1 is exceeded, it is considered that measurements in depth of the CMO must be made in order to characterize very precisely the nature of the defect.
- the inner surface of the IFS 1 can be painted, as is the case in the Airbus A380, or be exposed, as is the case for example in the Airbus A330.
- the first series of ultrasonic measurements 21 consists of sending ultrasonic waves at a certain incidence to the surface of the studied zone 5 and thus generating surface waves and then measuring the energy transmitted by the CMO between the emitter and the emitter. receiver.
- the surface of the zone to be studied is mechanically stressed by means of two transducers, namely a transmitter (subjected to an oscillating voltage) and a receiver (passive).
- the transducers are placed symmetrically with respect to a plane normal to the zone under study 5, and the amplitude of the ultrasonic wave transmitted by the surface waves is measured.
- This transmitter / receiver pair is moved to the defective zone.
- step 23 When the measured quantities exceed a predetermined threshold of NC2 nonconformity (step 23), it is deduced that this control is positive, that is to say that the CMO has a deep damage.
- This first series of ultrasonic measurements makes it possible to characterize the presence of a defect at depth in the CMO, when the threshold NC2 is exceeded.
- the second series of ultrasonic measurements consists in determining the electromechanical impedance of the studied area 5 of the CMO.
- the impedance resulting from this point ultrasonic measurement is then compared with a conformity threshold NC3 (step 27).
- test logics as a function of the results obtained by each of the aforementioned series of ultrasonic measurements are as follows, being noted that the solid and dotted lines connecting steps 23 and 27 in steps 29 and 39 do not establish any Hierarchy between the different possible options: different features were used for the sake of clarity.
- step 31 it may be decided or not to take the I FS for repair (step 31), and thus to maintain the aircraft on the ground or not.
- Either the two ultrasonic controls 21, 25 are positive, which means that there are therefore three positive non-destructive tests (step 39: the FTIR control + the two ultrasonic controls 21, 25), resulting in the repair of the IFS, and therefore the immobilization of the aircraft.
- the method according to the invention makes it possible to detect quickly and very reliably the degradation of the material by physico-chemical aging on the surface and inside a room. performed in CMO.
- This method makes it possible to define a reproducible and perfectly rational operating mode, in which we begin with conventional visual and acoustic tests, followed if necessary by measurements of surface realized very quickly by means of an apparatus with FTIR, themselves followed. if necessary by further measurements using ultrasound.
- This method according to the invention makes it possible to gradually characterize the defects observed, starting first with surface defects and then analyzing the internal structure of the CMO.
- the method according to the invention can be implemented in a manner carried out by the operators in charge of the maintenance of the aircraft propulsion units, either during routine visits or during special visits following observed incidents.
