Does this look like a solid repair?

Long story short: Chair decided to break randomly when I was using it, so I could not repair it for 2 days and had to not put even more stress on the back.

What I did was when I had time to take it out and work on it, I applied some JB Weld - not enough :/. So I had to come up with a different plan: Lowes sells something called FiberWeld by JB Weld, which is essentially epoxy coated fiberglass you roll onto the area as a one-shot thing; there's no reusing it once activated because you activate the entire roll :-(. Kind of wasteful, but I get it.

When I did this to the chair, I let it dry for like 4-5 hours to be sure once it cured and it seems like the side with the epoxy is more solid then the original not broken side of the chair 😂. I still intend to replace the chair as I do not trust it, but how long should this last?
