HOW STRONG IS ALUULA? | ALUULA VS DACRON LOAD TEST 

Hey, great video. One suggestion as a physicist, I might perform your tests with samples which are cut to smaller widths than the clamps. It appears from the failure of the ALUULA sample that the clamp edges might either be cutting into the fabric due to small angle differences at high loads, from the result of extreme differential shearing along the clamp edges. Mentally visualizing the warp/weft grid of the weave, on the load side of the clamp edge you can imagine the load inducing uniaxial deformation, such that the grid squares become more and more rectangular as they grow increasingly elongated and increasingly thin. Further away on the outside of the clamp edge, the grid will remain closer, geometrically-speaking, to their original square shapes. Along that boundary, however, the weave will deform into an increasingly extreme diamond-like pattern, the localization of extreme changes in grid shapes. This is not completely unlike the sphagettification resulting from the extreme differential effects of gravity around black holes). This nonuniform stress on each column in the weave probably vastly exceeds the readout on your machine, as the load essentially becomes focused on those minute regions surrounding the clamp edges. This is why the rip clearly occurs along those columnar boundaries. Its worth noting that it’s not as if nonuniform stresses aren’t more realistic in a variety of real-world situations, but for the purpose of more accurate and precise measurement worth re-testing with fabric cut to a width less than the clamps if you want to meet ASTM regulations. If you email ALUULA, I’m sure they’d provide you with a spec sheets with results from various ASTM tests, as a heuristic your results shouldn’t be far off, as they test multiple times to determine values that are of maximum likelihood.

That took away just about all my reservations regarding the material. Awesome job!

I'm interested to see the reaction of the aluula material on sharp objects, like when the kite is pumped and it scratches or touches sharp objects, whats the damage done by it.

That was a very satisfying video for a nerd kitesurfer like me!

You do all kinds of shedding on your channel 🤙🏽

SSSSSTTTTTOOOOOPPPPP teasing us already. Ship the kites we pre-ordered and paid for already!

Those are pretty compelling tests. Would like to know how well it handles UV. And of course the abrasion results would also be good to know.

awesome man, good to see practical evidence of this stuff. All I heard for the past year is that it's 10 times stronger and twice as light. well It's twice as strong according to your video which is still great. So far the advantages I see are mostly for low wind kiting, and for people crashing kites a lot. If you are into big air and never crash your kite, what are the added benefits? any benefits re the handling of the kite?

Thanks for the video. Do you know what material the fibers of the fabric aluula gold are made of? Unfortunately, I couldn't find anything on the Aluula homepage.🤔 Thanks! Best regards!

Where can I buy this fabric?

Dynea Tex ? Are you test ?

I am not surprised about the test results and think the fabric is amazing and the kites are amazing as well. I own several Roam-A's which I enjoy immensely, however I have had numerous issues with construction and material breakdown. Several kites were simply built wrong and don't fly right, some had bladder issues, and some have what appears to be a breakdown in the fabric, mostly on the leading edge where by appearance the laminate has "cracked" perpendicular to the tangen of the leading edge curvature. How is this going to play out with respect to strength and logevity of the kites? I have asked more times than I care to tell you about what my options are to solve this problem and to be honest quite disappointed. I am just trying to be honest about it and I feel like I had been patient about seeking a resolution. I have been kiting for 20+ years and owned lots of kites over that time and have never seen a situation like this before. I imagine you are aware of it...pretty much everyone in the insdustry seems to be. What are your thoughts about it?

...so if you make a kite from this "aluula" stuff..then its never gonna break last for ever?

vs Penta TX?

Nice demo video Reece! I want to try foiling with the Aluula roam 6m in 10 knots :) keep it up

That's wath we call a test 👌

Nice test! Subed

What’s the verdict 2 years on ? Anyone had one of the first kites that came on that could give us some feedback on how they hold up in the real world with regards to uv, sand on the beach etc

Good bro

Try it in -20c

is it GSM or grams?

The problem is that a kite with that material is to expensive.

The Dacron has more ink on it! Come on brother!

It doesn’t tear after it gets a pin hole, but that pin hole…

you are not comparing it to anything.. what's the point..

Nice playmobil haircut 😁

could you repeat the test but now with correct tensile specimen shapes please? Right now your test is a bit invalid since stress concentrations form around the clamps. Please visit en.wikipedia.org/wiki/Tensile_testing for some basic info

Same like Harith hair today. Cut short. His father delay cutting it. When he is small I cut his hair by myself. I cut all my boys hair by myself when they are young. I even cut my own hair when I was a teenager which my mom do not like I do so. Zouave = [C19: from F, from Zwawa, tribal name in Algeria] Page 1397
