can fiberglass insulation be used to make a bow and arrow?

i know they sell fiberglass mats that u use with epoxy for making things out of fiberglass but im wondering if i can use fiberglass insulation in place of the mats because i can get insulation for free and the mats r too expensive for me. and also, please dont answer my question by telling me where i can buy the mats or other ways of making a bow, instead, just answer the freakin question or dont reply to this question at all. thanks :)

Possibly. But probably not anything that's going to be usable. The fibers in insulation are, as LO says, a tangled mess. The tangled mess creates heat trapping loft, but as you've probably noticed, not much strength. By compressing it down, you can make a pretty dense stave. But because the fibers are running in random directions there's no strength along the length of the bow. Most likely, it'll just snap when trying to bend it. It's possible that by making the bow flat and really wide, you could get some strength. Taking insulation and rolling it into threads, you might be able to create some strong backing. Or maybe using a large comb you can align large clumps of fiber to run the same direction. Probably not worth the time and effort. Especially if you don't have access to a vacuum bagging machine.

I'm pretty sure that you couldn't do that. The fiberglass mats are weaved fiberglass threads, while insulation is a tangled mess of fibers. So, I hope this answers your question.
