Re: [VictorSuvorov] failure point on F111 fabric and Darcon lines
Dude those are a lot of Q's for 3 sentences.
Space is more than correct but I will add to it just because I feel Long-Winded today.
.
It's just like a skydiving canopy to what the human body can endure without losing consciousness (and-or) breaking bones on opening shock.
The Tensile Strength on a (individual) on an average is 550 lb. in the Dacron.
Breaklines and the loop (LRT set-up) on the risers Is much higher. Usually 1000 lb. spectra on the LRT set-up.
Those big beefy break lines are about 1500 lb.
.
I think that UV damage is the worst enemy for F-111. + dirt and grit in the fabric weave. It's a killer.
F-111 fabric tensile strength ? I don't know. If you poke a hole and start tearing it . Its not that tough but I have seen people hanging suspended by only the nylon fabric itself.
I have seen it tear quick and I have seen it get drug through the dirt and rock and slammed in a car door and still no holes.
Average # of jumps on a BASE canopy before it starts getting shabby/retirement, is about 300 - 800 jumps.
There is no set #. it is just in the amount of abuse the BASE jumper puts it through.
A good rule of thumb would be NEVER Lend your new BASE canopy for a friend to take out of town for a couple days.....
.
There is much documentation of Canopy opening shock bending and destroying Hardware on Riser and Harness container systems.
You put that all together combined with all the reinforcing/support tape and stitching that ties the line to fabric. The human Body is just a stick of Butter in comparison.
