EVC pop top crack repair thread,....can't find it.

[Tom Clark]

OK, acrylonitrile styrene acrylate. I’ve never worked with it, but if you can get epoxy, or some other viscous adhesive, to stick to it, a good repair could be made with unidirectional carbon fiber, which is very strong. Of course this would need to be painted.

The problem with filling the cracks I see represented in this thread, is it is not going to be a satisfactory repair in tension, which is a problem; the top flexes and the tops are stretched. Decades old plastic becomes brittle and parts.

With fiberglass boat hulls, we have made repairs of cracked hulls with tapered layering of high tensile strength cloth, carefully fairing and feathering the repair in preparation for gel coat or paint.

In the year 2025, small pieces of unidirectional carbon fiber cloth are remarkably inexpensive.
