Yeh mate no doubt it does depend a lot....it also depends on quite a few variables with the natural vs synthetic question as well. I have not done a whole lot of small diameter tests. Test #1 was paracord and it is crazily stronger considering it is with a knot as well! We would have to test a heap more pieces to get a cache of results to be able to do some comparisons. That's the idea though!Wonder how long they last in the wild. If you'll pardon the pun I suppoe it is a piece of string question really. Depending on exposure, width, weather conditions, humidity, job being used on etc.
Very interesting. Just as a comparison, what thicknesses of natural twine (Jute) and or nylon etc would be comparable in a similar knotted test? Just to give some sort of apple with African Artichokes comparison.
Interesting point mate, however it turns out testing the strength of the material pulling end to end will still be the breaking strength of the material when it's used to tie down a load. The difference is in whether the way the load is tied down will amplify the tension in the material and cause it to break. In general the rope will always break at it's tightest bend (knot) if not, it will break where it is damaged or weaker due to a splice or variable in the material. So its technically the same breaking strength, it's just that maybe the way it's tied down increases the force on it when the load moves around.Just out of curiosity I notice we are testing strength from end to end, but what about when tying down, we have no test for pressure applied to the middle (as if tying a ute load down)
Danhey Aussie have you tried a braiding technique with three bundles of fibers? i may test it myself, different types of weaving/braiding and rope making to see which gets the most out of the fibers, some reason i like to think that three stands twisted and braided together would be stronger.
Absolutely awesome thread AFCQ. I'll send you some Gymnostachys to test. It's my all time favourite.
P.S also added a small piece of Blue Mountains Restio, to try as well.
The Gymnostachys has been dried for about a month.
I'll do some with Gymea Lilly fronds some time as well, and get them off to you, they are quite strong when semi dry too.
Please do mate! I think that is a great idea. That will make it much easier to see where we are at and to compare results. Sounds great.Mate your Lomandra tests are really impressive! I was very surprised by that.
I have not made cordage since I took on my new job. I really need to get out more....
I am so impressed with the work you are doing though. This stuff is gold! Would you mind if I started to tabulate the results and give them their own sticky thread? would make it easy to see whats been tested, and how, and what we still need to do. Naturally we need to test more of the same materials by different makers and using different methods...
