RE: Composit skin hinges
Not really sure what you are refering too but I use kevlar for my hinges. Either sandwiched between the foam core and skin or laid on top of the balsa and sandwiched under the glass. The kevlar doesn't break down over time and is plenty flexible and strong.

Dunno a thing about Spectra fabric.
I don't do anything to keep the glue out. In fact it's all bagged at one time so there is plenty of glue in there. Once I cut the ailerons I give a bunch of wiggles back and forth and they loosen right up. Unlike FG or CF they don't break down the hinge just gets more flexible without breaking.

RE: Composit skin hinges
I'm refering to composite planes like Comp Arfs and Krills that have top hinged ailerons.Some have been known to crack or delam and was just wondering how you would go about repairing them.

spectra fabric is a UHMW polypropylene material, its less rigid than Kevlar and less abrasive to cutting tools spyder fishing line is a variant of spectra if i remember correctly
