How about this for Kevlar(r) shock cord?

[hpreric]

I have been looking for some lightweight yet strong shock cord material for a two-stage rocket I am planning. 3mm Kevlar(r) generally has an advertized strength of 1500 lbs among the various sites I have visited. I found this:

https://www.emmakites.com/500ft-1500lb-braid-kevlar-fiber-large-kite-line-string-us-stock_p614.html

It runs about 18 cents per foot and would be enough to last me for a lifetime.

Whaddayathink?

I have been looking for deals on kevlar cord too. This appears to be a good deal so I just went ahead and placed an order for 100 ft. with free shipping. I will let you know what I think of it.

As a secondary question, what kind of kite would need a 1500 lb line?

A *REALLY* Impressive one..... One i'd like to see. And let's hope the poor guy flying it is tied to the ground!

Actually, check out their site.... they have some pretty insane kites. It also looks like a great place to get Carbon Fiber rod for things like fin reinforcement.

My first thought was what kind of geek pays $200+ for a kite ... then I remembered my rocket collection ...

And with kites you generally get them back!

What about this for a streamer? https://www.emmakites.com/164-ft-minifun-ultra-light-kite-tail-pc40-1pcs_p477.html

I had a Friend in the Army that was into Kite-Boarding. It's like surfing on a Snowboard on Water while using a Kite to pull you around and allow you to jump really high into the Air. That Kite Site has "Lifters" listed as a class of Kite. I assume that's like the kind used for Kite-Boarding.
Then, I got to looking at some of the other Kites and now I want a Red and Black "Power Kite", whatever that is?

Check out this Kite! It can fly without any Wind!

Oh, and the "Lifters" on this Kite Site are used to fly "Line Laundry". Things like Cows and other weird stuff that attaches to the Line for Display.
I see a Kite in my Future. Perhaps a Kite with a Rocket that shoots up the Line.....

Or, a Kite the Fires Rockets!!! Fireworks are legal here, so theorhetically I could fire Bottle Rockets from the Kite, and it would have no bearing whatsoever on Hobby Model Rocketry, so safety rules would not apply!
A simple Radio Control will initiate the Firing. It's on!!!

I need a streamer like that. 16' long and weighs 11 grams. Woot!

I'll bet I could fly my Keychain Camera from a Kite too.

Thanks Mike. I didn't see any 1500 LB Kevlar(r) there. That seems to be the strength a lot of folks recommend for larger rockets.

I once flew my altimeter one and a keychain camera on a cheap walmart kite.... It was so high I couldn't even see the kite anymore....what a video! Highly recommended.

Also, thanks for the "kevlarstore" link. I've been needing a good source for that, I'm almost out of the smaller stuff.

If you want strong Kevlar for shock cord, check out Aramid mule tape https://www.neptco.com/Website/neptco.nsf/attachments/aramid/$file/aramid.pdf?Open

A 3000 or larger roll is pretty expensive, although about $0.30 a foot for 1/2" wide. Some of the suppliers resell by the foot.

I know the title says "Aramid" but all of the vendors I Googled says it is polyester. Does polyester have the same heat resistance as Kevlar(r)?

NEPTCO makes both polyester and aramid Muletape. They're different products. Aramid is the heat resistant one.

That is correct. Aramid is what Kevlar is made from. You have to remember that Kevlar is a brand name, not a material.

Well, I haven't tried that place's kevlar yet. However, when I looked at their site after this thread started, I saw some kite supplies that I wanted and at a good price. My package from them just arrived so the shipping speed was acceptable. The quality is no better than the cheap kites you find in Wally world and similar stores. However, that doesn't mean that it won't fly. For line laundry, that shouldn't be an issue. However, I think I will keep with my usual vendors for kite line and kevlar cord.
