Re: The plastic Boeing 787
Would the use of a paint that clearly shows impact level be of any use? Something with multiple layers of varying 'strength', may give a good indication of the possible level of internal damage.
Delamination was the biggest problem I've had with composite wing skins (model aircraft) and I always thought that a 3 dimensional weave would be a fine solution, especially with chunkier compaonents, but how to achieve this is another matter.
