How should you inspect a laminated fiberglass structure that has been damaged?

Inspecting a damaged laminated fiberglass structure requires a methodical and thorough approach to determine the extent of the damage and ensure the integrity of the material. Stripping the damaged area of all paint and shining a strong light through it is effective because it allows for a detailed examination of the structure.

When light is shone through the stripped area, any internal defects such as delaminations, cracks, or voids will become more visible. This technique enhances visibility of flaws that may not be apparent on the surface, providing insight into the actual condition of the fiberglass layers. It is crucial to assess whether the integrity has been compromised or if the damage is superficial.

Other approaches, such as simply painting over the damaged area or using a magnifying glass, do not provide the depth of inspection necessary to accurately evaluate serious damage. Replacing the entire structure may be a drastic solution if the damage is minor and can be repaired, which would not be a responsible use of resources. Hence, the proper inspection method involves stripping and utilizing light to get a comprehensive view of the underlying material condition.
