...Abstract Abstract Lightning damage in polymer composites, as in metal structures, is manifested by damage at both the macroscopic or visual level and within the material microstructure. In addition to visual damage assessment, non-destructive inspection techniques are employed to detect damage...

... in a parked position and switched off, the failures would have been significantly less. Even if the electric field from a lightning strike turns on both nFET and pFET channels for a very short time, it usually wouldn’t cause any damage as long as the CMOS circuitry is in off-state and not electrically powered...

... rain erosion coatings and paints are available to prevent surface wear. Lightning is also a danger to composites; a direct strike can cause considerable damage to a laminate. To prevent it, conductive surfaces are applied to lightning strike susceptible surfaces. In cases in which the substructure...

... to label may be the side opposite the polishing face. An easy method that can be used to document the sections is to take a digital photograph of the composite material and then organize the sections. Figure 2.2 shows a composite part that was damaged and removed from an aircraft for analysis. After...

If the features to be investigated are not evident on the surface of a part, sections should be taken throughout the part and analyzed using reflected-light illumination to find the areas of interest. When the location is determined...

... of a component, assembly, or structure can be multilevel. In other words, a failure should not be viewed as a single event. The actual physical failure—a fracture, an explosion, damage by heat or corrosion—is the most obvious. However, other levels of failures generally exist that allow the physical event...
