Learn about the various ways a sandwich composite can be properly repaired.
- [Instructor] Sandwich components are composed…of two laminated surfaces separated by core.…Remember that core is that honeycomb shape,…and it's used for strengthening the composite.…Now, when you're repairing a solid laminate,…the method that you use is very different…than when repairing core laminate.…So, if you have damage to your core,…and it's let's say smaller than half an inch,…you can do something, use a filler or what's called potting…to just pack it into the core.…
Now one of the things you have to be careful of…when you use a potting compound,…it will restore some of the strength, but it adds weight.…So the potting compound is heavier.…You pack it into the core and it might affect…the flight control bounds,…depending on how much potting compound is used.…Next, for larger repairs, the core can be spliced out,…and you can reinstall new core into the void…from where you took the original core out.…
So for something like that,…you would have to use an adhesive film…and cut out the old core, put the new film in the bottom,…
