 CONTROL and LABORATORY
 |
|
Quality insurance and products control are implemented at all corporate levels. Stringent monitoring is ensured by the Quality Control department and the laboratory : non-destructive tests, mechanical and physic-chemical tests, PARETO, SPC, ADEQUA methods.
 THE MAIN NON DESTRUCTIVE TESTS
BACUS METALSCAN WATER JET
© EADS Composites Aquitaine | |
The origin of the defects in composite structures may come from the material itself and the variation of its properties during the manufacturing process but also from structural discontinuities resulting from production phase or service conditions. The non destructive tests are fully used at 2 levels :
 |
in follow-up of characterization tests and composite structures qualification |
|
in material control so as to detect eventual fabrication defects or damages sustained in service. |
EADS Composites Aquitaine is equipped with powerful non destructive tests using in particular ultra-sound techniques (A/SCAN and C/SCAN).
C/SCAN mean with water jet :
|
Useful dimension : 3 000 x 5 000 x 1 100 mm |
|
Item configuration : positioned horizontally and vertically water jets |
|
Centre to centre distance jets : adjustable between 200 and 500 mm |
|
Actual dimension of installation : 6000 x 4000 x 1 500 mm and possibility of controlling an item in several times according to its geometry. |
|
Frequencies of check : 1 MHz, 2.5 MHz, 5 MHz and 10 MHz in simple transmission (E/R) |
|
Number of motorized axis : X – Y –Z (including 2 axis monitored simultaneously) |
|
Items support : existing, flexible adaptable to several items and plenty of adaptation possibilities. |
|
Programming of trajectory of scanning : configuration datas indicated in every control instruction through a technician COFREND level 2 and approved by a technician COFREND level 3. |
|
Operating software image processing : BACUS version 5.5 G developed by METALSCAN and validated by EADS Composites Aquitaine |
|
Type of C/SCAN mapping : display unit amplitude (DB, %) and flight time (mm, pli, ms).
C/SCAN COLOR DISPLAY AMPLITUDE (%)
|
C/SCAN B/W DISPLAY AMPLITUDE (%)
| |
|
Mappings FORMATS : generated by BACUS specific to METALSCAN - not exploitable under another software of picture treatment. |
|
Data-processing filing : CD, DVD |
THE LABORATORY FOR PHYSICAL CHEMICAL and MECHANICAL TESTING :
Our laboratory offers several types of tests related to the large scale of EADS Composites Aquitaine activities. It places at disposal its means and its skills so as to carry out with efficiency and quality internal and external analysis.
