ThermographieIndex. décimale : 668.4 Plastiques, vinyles Résumé : Aeronautical and automotive fibre composite structures often have curved surfaces and complex material properties. Therefore, non-destructive testing is challenging when using classical methods such as X-ray or ultrasound inspection. This paper presents two alternative methods that can cope with these challenges : active thermography and shearography.

Détection de défauts (Ingénierie)Index. décimale : 668.4 Plastiques, vinyles Résumé : Fiber-reinforced plastic composites (FRP) have great potential for making the vehicles of the future even more lightweight and economical. It is important to start thinking now about the non-destructive testing (NDT) of the fiber composite parts of tomorrow with the aim of providing reliable, fast and inexpensive evidence of typical material defects before and during service.

ThermographieIndex. décimale : 667.9 Revêtements et enduits Résumé : A method of assessing uneven paint coatings is described, wherein a painted surface is rapidly heated by a light flash and the subsequent surface temperature changes are monitored using thermography. This method exploits the differences in dynamic heat transport caused by variations in paint thickness, using thermographic observation to track differences in temperature related to thickness. During trials with intentionally uneven test specimens spray coated with blackbody paint or red, blue, and green acrylic lacquers, we determined that surfaces with thinner paint coatings exhibited lower temperatures. Based on our findings, this article also discusses the theoretical basis of the detection method. While this technique can detect uneven painting, it is difficult to determine a quantitative relationship between temperature variations in the coated surfaces and paint thickness, since the relationship is dependent not only on the particular substrate and paint, but also on the optical reflectance of the paint. We consider that the proposed method is currently capable of detecting uneven paint coatings with variations in thickness of approximately 20 μm, although improvements in detection resolution are possible. Although detection sensitivity is somewhat low, this technique allows rapid analysis of coatings to assess evenness through visual examination.

ThermocinétiqueIndex. décimale : 668.3 Adhésifs et produits semblables Résumé : Electronic components that contain a die require a path by which excess heat can be removed from the component package. In low-voltage plastic-encapsulated microcircuits, the heat may simply travel by conduction through the die attach and the die paddle for dissipation through the bottom of the package. In higher-voltage integrated circuit (IC) packages and in larger items such as insulated-gate bipolar transistor (IGBT) modules, a separate metal heat sink may be adhesively bonded to the package. The heat sink promotes conduction and prevents the temperature of the die from rising to a point where the circuitry on the die will fail. The bonding agent holding the heat sink in place may be solder, epoxy or another material. The heat sink is usually on the bottom of the component package, although some flip chips have a heat sink on the top side of the package. Note de contenu : - FIGURES : 1. Ultrasonic echoes from beneath this heat sink revealed numerous voids (white features) in the adhesive material - 2. Focused and gated on the die, ultrasound showed voids in the die attach in this IGBT module, as well as the acoustic shadows of numerous larger voids in the solder - 3. This image of a warped IGBT raft used ultrasound to report distance from the heat sink as color for the various regions of the heat sink and for the voids at various depths in the solder En ligne : http://www.adhesivesmag.com/articles/95524-nondestructive-inspection-for-heat-si [...] Format de la ressource électronique : Web Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=28752
