Default Steel vs. kevlar cable, breaking strength vs. working load?

For a project I can use either kevlar cord or thin steel cable.

The breaking strength for a given diameter (at least in the small sizes)
comes out very very close to each other: in one instance, .31" steel
cable was rated at 184 lbs, while .3125" kevlar cord was rated at 175 lbs.

Everywhere that sells the stuff usually gives the breaking strengths of
both, but not the working loads.

From other places online I gather that the typical rated working load
for steel cable is 20% of the breaking strength. Is this assumption
reasonable?

And what is the % for kevlar rope? The same, or higher or lower?

(-I know that there are other factors like kevlar's higher price, lower
abrasion resistance ect, but those aren't significant in this instance-)

You could probably also use uhmw polyethylene. The plastic fibers
have some advantages over steel in that they do not rust , are lighter
and do not stretch as much as steel. But have some disadvantages
too. Kevlar degrades from ultraviolet. UHMW loses strength if
heated. You can get uhmw fiber from places that sell fishing line. I
suspect people use 20% of breaking strength for working load in pretty
much all cases.

From WIKI.
Fiber applications

Ballistic vests can be made of UHMWPE.

Dyneema and Spectra are gel spun through a spinneret to form oriented-
strand synthetic fibers of UHMWPE, which have yield strengths as high
as 2.4 GPa (350,000 psi) and specific gravity as low as 0.97 (for
Dyneema SK75).[4] High-strength steels have comparable yield
strengths, and low-carbon steels have yield strengths much lower
(around 0.5 GPa). Since steel has a specific gravity of roughly 7.8,
this gives strength-to-weight ratios for these materials in a range
from 10 to 100 times higher than steel. Strength-to-weight ratios for
Dyneema are about 40% higher than for aramid.

UHMWPE fibers are used in armor, in particular, personal armor and on
occasion as vehicle armor, cut-resistant gloves, bow strings, climbing
equipment, fishing line, spear lines for spearguns, high-performance
sails, suspension lines on sport parachutes and paragliders, rigging
in yachting, kites, and kites lines for kites sports. Spectra is also
used as a high-end wakeboard line.

For personal armor, the fibers are, in general, aligned and bonded
into sheets, which are then layered at various angles to give the
resulting composite material strength in all directions.[5] [6]
Recently developed additions to the US Military's Interceptor body
armor, designed to offer arm and leg protection, are said to utilize a
form of Spectra or Dyneema fabric.[7] Dyneema provides puncture
resistance to protective clothing in the sport of fencing.

Spun UHMWPE fibers excel as fishing line, as they have less stretch,
are more abrasion-resistant, and are thinner than traditional
monofilament line.

In climbing, cord and webbing made of combinations of UHMWPE and nylon
yarn have gained popularity for their low weight and bulk, though,
unlike their nylon counterparts, they exhibit very low elasticity,
making them unsuitable for limiting forces in a fall. Also, low
elasticity translates to low toughness. The fiber's very high
lubricity leads to poor knot-holding ability, and has led to the
recommendation to use the triple fisherman's knot rather than the
traditional double fisherman's knot in 6mm UHMWPE core cord to avoid a
particular failure mechanism of the double fisherman's, where first
the sheath fails at the knot, then the core slips through.[8][9]

Owing to its low density, ships' hawsers and cables can be made from
the fibre, and float on sea water. "Spec Lines" as they are called in
the towboat community are commonly used for face wires.

It is used in skis and snowboards, often in combination with carbon
fiber, reinforcing the fiberglass composite material, adding stiffness
and improving its flex characteristics. The UHMWPE is often used as
the base layer, which contacts the snow, and includes abrasives to
absorb and retain wax.

High-performance lines (such as backstays) for sailing and parasailing
are made of UHMWPE, due to their low stretch, high strength, and low
weight.[10]

Dyneema was used for the 30-kilometre space tether in the ESA/Russian
Young Engineers' Satellite 2 of September, 2007.

The extremely low friction coefficient of UHMWPE makes it a common
topsheet for boxes in terrain park.[citation needed]

Apparently the working load is an arbitrary percentage of the measured
breaking strength. see:

http://donsnotes.com/products/ropes.html
http://www.jamestowndistributors.com...+England+Ropes
http://www.phoenixrope.com/usage.html

See
http://www.tpub.com/content/MIL-SPEC...1145E00002.htm
for a sample Mil spec. Note only breaking strength specified.

I found 14% of breaking strength for industrial slings. What are the
consequences if it fails?

doesn't kevlar rope stretch under constant loads? there are many
different kinds of synthetic ropes used in boats in place of rod or
cable rigging.

Kevlar's elastic modulus in tension is extraordinary -- for Kevlar 49, it's
on the order of steel. But rope is more commonly made of Kevlar 29, which
has a little more than half of the modulus of Kevlar 49.

The "constant load" issue is a combination of elastic modulus and creep. It
will creep, but not very much.

Here are some useful comparisons of Kevlar, Spectra (polyethylene) and
steel. They're worth reading if you're going to do anything that's
load-bearing with either of those synthetics:

Here's a graph that shows relative creep for Kevlar 29 and 49 versus steel.
Keep in mind that this is at 50% of breaking strength, so the absolute
values are 'way higher than they would be in a normal application. I'm
guessing that the relative rates are similar at lower loads:

Ive had poor luck with Kevlar rope in my sailboats here in the desert,
particulaly during the hot summer months. Rig tight and a half hour
later..stuff is slack.

Spectra...good stuff..and it too will stretch a smidge..but nothing like
kevlar

I just *have* to ask -- what do you do with a sailboat in the
desert? I presume that there is some water somewhere within trailering
range, but at today's fuel costs, I would consider it not very
practical.

Granted -- I love sailing -- but I did it on my father's boat on
the Chesapeake mostly, and those days are long gone now.

There are hummm 6 lakes within an hour driving time of my
homestead..several of them pretty good sized. Dams and a number of
county parks where the water is used for both recreation and ag.

Plus the Pacific is within an hour and a half from my front door.

Ive sailed on all of them and in fact..stepped aside after winning the
Sierra Sailing Assoc regattas, 4 yrs in a row...generating a bit of
miff..and became a race official for a few years, before going back and
winning again.

Lots and lots of ski boats around the desert areas of California. We
have a lot of such lakes. We cant get it all from wells or the
California Aquaduct. Shrug.

Although parts of California are in the Sonoran, Mojave, and Colorado
Deserts, it also has over 3,000 named lakes. Many are man-made
reservoirs. Central and Northern California have more due to the
Rocky Mountain streams and rivers.

When I lived in Vista, CA, we had mile-high mountains, deserts,
rivers, lakes, the Salton Sea, and the Pacific Ocean all within an
hour of us. Pick a climate and take a short drive. It was great.

Ive had poor luck with Kevlar rope in my sailboats here in the desert,
particulaly during the hot summer months. Rig tight and a half hour
later..stuff is slack.

I just *have* to ask -- what do you do with a sailboat in the
desert? I presume that there is some water somewhere within trailering
range, but at today's fuel costs, I would consider it not very
practical.

There are hummm 6 lakes within an hour driving time of my
homestead..several of them pretty good sized. Dams and a number of
county parks where the water is used for both recreation and ag.


O.K.

Plus the Pacific is within an hour and a half from my front door.


Not too bad, then.

Ive sailed on all of them and in fact..stepped aside after winning the
Sierra Sailing Assoc regattas, 4 yrs in a row...generating a bit of
miff..and became a race official for a few years, before going back and
winning again.


Nice!

Lots and lots of ski boats around the desert areas of California. We
have a lot of such lakes. We cant get it all from wells or the
California Aquaduct. Shrug.

Google "california central valley lakes"


O.K. Thanks. Just when you said "desert", it sort of implied
no nearby water to me. :-)


Although parts of California are in the Sonoran, Mojave, and Colorado
Deserts, it also has over 3,000 named lakes. Many are man-made
reservoirs. Central and Northern California have more due to the
Rocky Mountain streams and rivers.


Rocky Mountain??? VBG


When I lived in Vista, CA, we had mile-high mountains, deserts,
rivers, lakes, the Salton Sea, and the Pacific Ocean all within an
hour of us. Pick a climate and take a short drive. It was great.

There are a couple big reserviors smack dab in the Mojave desert
too..and then we have Lave Havasu not far from Death Valley on the
California/Aridzona desert.


I grew up in South Texas -- and the only nearby water (other
than cattle tanks) was the Nueces river -- which was mud most of the
year. Lots of cactus, not much sailing opportunity. :-)

Oh..thats where the put the original London Bridge when they bought it
from London.....G


O.K. I remember that. A big fuss in the news about that. :-)


As for my area...

Nice enough -- and lots more choices than I grew up around --
until I moved back to the Washington DC area with my folks (I was with
my grandparents), and where my father kept his boat in a river just off
the Chesapeake. For many of the years, it was a Wianno Sr. (25' gaff
rigged wooden-hulled, centerboard sloop), and the last years it was a
fibreglass Gladiator Marconi rigged. The centerboard gave quite an
advantage during certain races, because the Chesapeake has a lot of
shallow areas. :-)

Ive owned about 10 sailboats in the past 20 yrs.

Currently I own a AMF Force 5 (13' mostly single hander), a mid 1970s
Esenada 20 and a '78 Hobi 16 and 3 windsurfers.

Im giving the Hobi away to a friend to putter with. He has been storing
the Ensenada 20 for the past 12 or so years...he wanted to buy it..but
never put in in the water. So I told him if he wanted the Hobi..put
tires on it, drag the Ensenada back to my place, and haull the Hobi
home. He agreed readily.

I recently gave away a '78 Chrysler 15 fishing boat, to a guy in
Bakersfield.

https://picasaweb.google.com/1040422...atForSaleCHEAP

I rather miss my old Thistle (1308) which I sold some years ago, as I
wasnt racing anymore and was short of crew..and I wanted someone to
enjoy it.

Since the other half left..taking a huge chunk of my expenses with her
G last month, Im going to have to make some tough decisions. Doing
what Im doing..fixing machinery..hasnt been particularly lucrative for
the past 3 yrs...Californa manufacturing is..dying..Im probably going to
have to shut down my company and go to work for some oil industry
related firm, so Ill be home a lot more and will be able to use my toys
a lot more.

Still havent decided what to do yet..but Im going to have to do
something before the first of the year..or before. And frankly..after
working in LA for the past 12-14 yrs..driving down on Mondays or
Tuesdays..and coming home Fridays...Im getting damned tired of it.
It cost me a marraige in part...shrug...

Anyways..I went out to Buena Vista Lake this afternoon for Labor
Day..took a couple friends with me...no one had a sail boat out there.
Which surprised me. Perhaps sailing isnt as popular as it was once,
around here.

Im getting over it. Came as quite a shock..but I should have seen it
coming. Good days..and bad days. Like a death. Shrug. I was only
married to her for 38 yrs, off and on..mostly on. Last time she
ran..2001 or there abouts..I told her she would never be allowed back if
it happened again. And I do keep my word. She had serious medical
issues..and Ive cared for her for 10 yrs. Now that she decided she didnt
like living in a small town, and refused to work..wanted me to provide
everything on her terms..and left when I couldnt give her enough of
what she wanted..money and entertainment..shrug... its forever done.

I do honestly love her..but I cant provide life to her specs. So she
now gets to live with her son and daughter in law, two grand children,
in a basement apartment in Utah. All on the sons Social Security and the
daughter in laws welfare.Good luck on that.

She called and asked to be paid $200 a month until she could find a job
or get Social Security...and I told her Id think about it. And I
certainly did think about it. For an entire 100 nanoseconds. And the
answer is....no.

Shrug.

Now I have to get used to being by myself again, its not the first time.
Shrug again.

But..sigh...I do have good days..and bad days. And when she calls ..Ive
had to simply not answer..let them go to the voice mail. Ive zero
interest in talking to her any longer. I hope the feelings dont turn to
hate for her. Really. So now that she is gone....I try to keep her out
of my mind. Ill probably wind up hating her though, after some thought.

160 miles each way..tends to wear out vehicles, eat up money for service
and fuel and tires...320 miles a week just to get to work. And at the
price of fuel/registration/parts etc etc....Its almost more than I can
afford. Not having very many customers anymore doesnt help either...10
went out of business..7 have left the state for friendlier climes.

in a basement apartment in Utah. All on the sons Social Security and the
daughter in laws welfare.Good luck on that.


Indeed. It does not sound like something which will provide her
desires, or even her needs.

She called and asked to be paid $200 a month until she could find a job
or get Social Security...and I told her Id think about it. And I
certainly did think about it. For an entire 100 nanoseconds. And the
answer is....no.


Understood. It is not as though you have that kind of money to
spare these days. If you did, she might not have decided to leave.


Ayup. She was spending $25-50 in the indian casinos every month or two,
but spending $40 in gas getting there...sending money orders off to the
kids, buying useless stuff she had closets full of ....Ive been finding
receipts and tokens and whatnot as I clean out her Stuff, along with all
sorts of other "spents" I wasnt aware of.

When I asked her why she left..she said it was because of the "bull****"
...and when I asked her to define "bull****"...she started sucking wind
and desperately trying to make stuff up. Shrug..she wasnt happy here,
so off she goes. Hope the new owner..when she finds one..will have lots
of money. But..I dont think she will ever be "happy"

Not my problem.
Not any more.

Shrug.

Now I have to get used to being by myself again, its not the first time.
Shrug again.

But..sigh...I do have good days..and bad days. And when she calls ..Ive
had to simply not answer..let them go to the voice mail. Ive zero
interest in talking to her any longer. I hope the feelings dont turn to
hate for her. Really. So now that she is gone....I try to keep her out
of my mind. Ill probably wind up hating her though, after some thought.
Which isnt all bad.


Good luck.

[ ... ]

It is a killer of a schedule, for sure.


160 miles each way..tends to wear out vehicles, eat up money for service
and fuel and tires...320 miles a week just to get to work. And at the
price of fuel/registration/parts etc etc....Its almost more than I can
afford. Not having very many customers anymore doesnt help either...10
went out of business..7 have left the state for friendlier climes.

Anyways..I went out to Buena Vista Lake this afternoon for Labor
Day..took a couple friends with me...no one had a sail boat out there.
Which surprised me. Perhaps sailing isnt as popular as it was once,
around here.

They would rather burn up gasoline?


Evidently so. Or they dont have the money to fix up the boats..and the
sit rotting in back yards.


That could be, I guess. But then they might not be able to
afford the fuel for the "stinkpots" either.


Lots and lots of old and newer boats around here. Which is why I simply
gave away the Chrysler a couple weeks ago. Good solid hull, no engine.
Lots of engines in peoples back yards on sun rotted boats.

Good Luck,
DoN.

Default Steel vs. kevlar cable, breaking strength vs. working load?



There's "guy unwire" for towers called Phillystran
http://www.phillystran.com/rope-products-application.htm

I'm surprised to hear about such things stretching; it was very
popular for antenna towers; strong, did not stretch, and did not
alter the radiation pattern.

Default Steel vs. kevlar cable, breaking strength vs. working load?

On Thursday, September 1, 2011 at 4:09:10 AM UTC+5:30, DougC wrote:
For a project I can use either kevlar cord or thin steel cable.

The breaking strength for a given diameter (at least in the small sizes)
comes out very very close to each other: in one instance, .31" steel
cable was rated at 184 lbs, while .3125" kevlar cord was rated at 175 lbs.

Everywhere that sells the stuff usually gives the breaking strengths of
both, but not the working loads.

From other places online I gather that the typical rated working load
for steel cable is 20% of the breaking strength. Is this assumption
reasonable?

And what is the % for kevlar rope? The same, or higher or lower?

(-I know that there are other factors like kevlar's higher price, lower
abrasion resistance ect, but those aren't significant in this instance-)
