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-) |

(-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. Dan 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] [edit] |

The matter is in regards to the wire used in bicycle tire beads. Tire & rim systems have changed over time and many kevlar-bead tires are designated as not suitable for newer tubeless rims where steel-bead tires are--yet the bead diameters (and breaking strengths) of both is very close. The elongation under breaking of kevlar ranges from as little as 1.2X steel to ~2x steel wire of the same size. Might or might not be an issue... |

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: http://gertrude-old.case.edu/276/materials/21.htm (Scroll down until you see the rear end of the blond girl; the graph is directly across from her butt) -- Ed Huntress |

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. -- "The danger to America is not Barack Obama but a citizenry capable of entrusting a man like him with the Presidency. It will be far easier to limit and undo the follies of an Obama presidency than to restore the necessary common sense and good judgment to a depraved electorate willing to have such a man for their? president.. Blaming the prince of the fools should not blind anyone to the vast confederacy of fools that made him their prince". |

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. -- A host is a host from coast to & no one will talk to a host that's close........[v].(301) 56-LINUX Unless the host (that isn't close).........................pob 1433 is busy, hung or dead....................................20915-1433 |

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-) |
