Can you Bend a Fiberglass Rod with Heat?

- Having reinforced a bow with fiberglass rods, I really wanted to see if I'd be able to apply heat to a fiberglass rod and cause permanent deformation without causing the fibers to begin to break.
I created this video with the RUclips Video Editor ( / editor )
You need to apply the bend and keep it applied while heating, the key is the temp you get it to, but you keep the bend during the whole process, including during cooling
Thanks for the video. I was going to try do the same thing. You save me some time.
Huri Santos hai sir
Neat test. Unfortunately the idea is ultimately doomed because the fibers need to slide and stretch in relation to one another - this cannot occur as they are bonded together rigidly- even if some softening of the resin occurs. Eg, the length of the glass on the inside of the bend needs to be less than the length of the glass on the outside. Even if you COULD warm the material and cool to achieve a curve it would not have the same strength properties and would always fight the reshaped resin and want to return to straight. Sorry if this is discussed in your video, I skipped a bit. Thanks for taking the time to do it and show us all!
Aww man, I wish you'd succeeded...I have in mind building a few smaller bows for my grandkids...
Well, I need to pursue another course of action...🤷🏻♂️👍🏻🙂
Thanks for sharing this experience.
🙂👍🏻🇨🇦
Good experiment 👍
Can you bending plat carbon twill 1 mm ?
Fiber glass it self is naturally heat resistant.. hence the use of it in so many fire resistant applications.. on the other hand.. apoxy resin+ hardener.. the stuff we use to form things out of fiber glass..
Depending on what type of apoxy it is.. will melt/ deform , or become a liquid state once heated..
epoxy resin is a thermoset plastic, it will never melt it'll only burn
But if you put the fiberglass rod inside a mold with the shape of the bend and apply heat and let it cool, it would be the same shape?
Yes, it is right, practically I did it,
mm when we were camping in extreme heat the fibre glass rods in our swags collapsed like that during the day. Even after getting different replacement rods same thing happened.
Yep, so heat and fiberglass, definitely a no-go. I'm going to try other ways of making a reflexed, reinforced bow.

Have you considered spring steel?
so what is the exact snapping strength of this rod without heat?

I think U just over heated it... I've read some have managed a decent bend on certain fiberglass rods.........
Really, huh? OK, I'll try again, then :) It's only a dollar a try anyhow...
The way it was said to be done in the forum I rear was that he was bending it AS he was heating it..... and it worked. Maybe thats the trick?

to fix a bend in preformed rod you need to laminate two pieces of flat or half round, the only way to get a bent round rod is to make it that way in the first place!
Thanks 👍
1/3 of the video is you shootinf heat at the rod . . Couldve been filmed in a more entertaining way, nice try tho m
use flat fiberglass in the first place and abandon the rods all together fiberglass rods are not the answer in the first place my thought
Interesting.
Also a question.. why the trying to reinforce PVC with fiberglass any way??
Fiberglass in it self is a great bow making material, if a person wants to go through all the trouble of messing with the nasty stuff. But in essence a "PVC " bow reinforced with fiberglass , really isn't a PVC bow .. more like a fiber glass bow , wrapped in PVC.. and honestly, you can make PVC bows with 1 in ch40.. that can draw 80+ lbs with out reinforcement if formed right.. but who needs an 80lb draw weight any way?.. hunting class bows made on a commercial level , range from 45# to 65# at 28in.. any large game animal in N. America can be harvested with a 50# at 28 in bow..
So I guess I really don't understand the need for a "fiberglass" reinforced PVC bow.
Just food for thought.
Need for it? Nobody needs an 80# bow, or any bow at all :)
I WANT it, that's about it.
I'm not a hunter, not much of a target shooter, just a tinkerer, and I want to see how far I can push the material. I wanted better performance out of this bow, and I got it - not efficiently (35 pounds more for about 30 fps more, at least in my first VERY abbreviated test).
Who cares what material the bow's made of? I just want to make bows, period :)
littlelioness001 my country doesn't sell sch40 pvc, pvc sold around is so thin so... the fiberglass reinforced would be the only options
It’s a way to help make a higher draw weight and longer pvc bows without using thicker pipes. Since the thinner pipes are lighter on mass and can usually result in a more efficient bow performance wise and the fiberglass doesn’t add much mass. Especially only reinforcing the body of the limbs and leaving the tips lighter and recurving them.
The fibreglass in PVC is a modern material composite bow, akin to the horn and sinew bows. Increasing power and efficiency over a shorter limb length and improving "pipe torqueing" at the same time.
