coolamber Posted October 2, 2007 Share Posted October 2, 2007 I need some advice on how to repair some layup issues. I did the big layup on the fuselage sides and when I was done stippling out all the bubbles I layed on my layer of peel ply. Once the peel ply was down I was pretty much unable to do any further inspection. Well during cure a few areas developed bubbles between the foam and fiberglass. Maybe I missed them during the layup. MGS and blue foam seems to make them more difficult to notice. Anyway some are just the small 1mm or less bubbles that I cannot really worry about.For the larger ones, I was considering using a 18 gauge hypodermic and syringe from the unglassed side to back fill the spaces with epoxy. I will do this when I pop the sides from the jigs. Is this a valid repair technique? One of the areas that has bubbles is within the 10" radius of the canard attachment point, so the plans seem to indicate this is a critical area. For the inspection 10% rule, does the rejection mean that 10% of a 6"x6" square area is air, or 10% of the area has portions with air? Thanks much!
