Shelf Life on Fiberglass?

Hey folks,

So, a relative of mine has an old fiberglass recurve that's probably about 50 years old at this time. It hasn't been strung in a long time, so I'm wondering if it's safe to even try? From what I can tell, both limbs are fiberglass with a rubberized handle in the middle. Not sure of the poundage, but I believe it was in the 40-45# range.

Part of my job is fiberglass repairs to propeller blades. Our paperwork for repairs, and any maintenance, requires lot numbers and expiration dates of materials (chemicals) and calibration dates of tooling. With that said, I’ve never seen expiration dates for fiberglass. I’d be more concerned with the resin (glue) that was used to soak and adhere the fiberglass together. However, any expiration date on the resin is before it’s mixed (two part type) and cured. But the older it gets, some resins have a tendency of becoming brittle depending on the type and what atmospheric conditions it’s been exposed to.

Shelf life was probably the wrong term to use, apologies; I'm just worried it's gonna snap if I string it. The limbs still seem pretty solid? It's just been in a closet, indoors, as far as I know.

I’d suspect it’s good. But it will depend on the resin. Bows are not my specialty but it would make sense that there’s more than just fiberglass and glue. The limbs more than likely have a core that support the draw weight. I’d try it.

My kids learned on an old bow, 50 yrs. Old. No problem.
String it and let them fly.
Where eye protection.

Curious any name on the bow? Ben Pearson bows come to mind. I have a few older ones and no issues shooting them?

I'd also suggest a heavy jacket and gloves for the first few shots.

I haven't noticed anything yet, but I'll check next time I see it?

Hahaha Yeah, I was thinking of that, and maybe my paintball mask.

If it wasn't in the sunlight, it ought to be fine. Wear the stuff above and take a close look after each of the first lot of shots.

And a forearm guard can't hurt either.
