At the risk of sounding silly, has anyone ever tried making a parachute out of nomex instead of protecting it with that?

I'll sell one or two if you let me know the size.At the risk of sounding silly, has anyone ever tried making a parachute out of nomex instead of protecting it with that?

Man wish I had that kind of money!! $50 for a twelve inch chute :shock:
But 7ft is only $110 which is cheaper than most nylon chutes.

Kevlar is certainly available in 1.0 and 1.7 oz./sqyd fabric https://www.cstsales.com/aramid_fabric.html but it is expensive. Nomex should be available in similar weights.
Fiber glass is available in 0.6, 0.7, 1.4 and 1.6 oz/sqyd from the same supplier https://www.cstsales.com/e_glass_cloth.html at reasonable prices and you used to able to purchase surplus flare parachutes made of fiberglass from several vendors. It's flameproof as well.
These are the same weights or lower than the standard rip-stop hobby rocket parachutes which tend to be overbuilt with 1.7 oz. per sqyd. Military Parachute Fabric Specifications can be downloaded from https://www.perftex.com/specificati...arycanopy-specification-outline/download.html
You can get flame resistant rip-stop nylon but it is heavier than the basic fabric because the flame resistance comes from a coating. https://www.onlinefabricstore.net/c...oup-nylon/use-general-purpose/type-fabric.htm shows a 1.9 oz/sqyd RS nylon when coated with the retardant coating weighing 2.3 oz/sqyd.

At my work we had a chute for the Huygens lander. It was Kevlar that looked like yellow silk. IIRC it was 15 feet diameter and packed 3" dia x 2 1/2" tall. We had to send it back to Marconi.
We made the ejection charge.
