Published 26 Apr 2020

The purpose of this experiment is to test various cuben fiber tarp tieouts (manufactured using materials that the typical person can easily purchase and acquire) used on a cuben fiber tarp. The goal is to give a general idea of the strongest and weakest joint designs on the corner tieout of a tarp.

@windriver23633 years ago If the parent material is the weak point, I think to get more strength one would need to increase the size of the reinforcement patch.
I always thing of stress in fabric as force over a distance, where the distance might the length of stitching in the grosgrain tie out, or the perimeter of the reinforcement patch. The larger the distance you can distribute the force over, the more threads you incorporate into the bond, and the stronger it becomes.
Also how does one acquire 3M transfer tape without paying $500+ for an entire case? Are there any tapes or adhesives you recommend other than the ones used in this video? ... 1

@MrEr1c4 years ago Did you use any type of adhesive promoter and how long did you wait for each adhesive to cure before testing or even sewing on the grosgrain? I think these could be potential contributing factors. I do wonder what the effect of the thickness of the adhesive is to it's overall strength.I also agree that the sew only method at ~168lbs could be more than necessary considering the possibility of stakes pulling out and that load being distributed among the tie outs. Thank you very much for this information. As you are the original author, I encourage you to post this on bpl's MYOG section. ... 1

@leonidgorny90823 years ago Great video I was looking for something like that for a long time!
Did you use 0.51 cuben as base material and reinforcement patches? 1

@preacherman90182 years ago I appreciate the textile engineering test.
I will subscribe. Hopefully you will/ have done more testing based on information gathered and questions remaining. I know that most of us here are interested in MYOG based materials that do not require an additional fortune or specialized equipment available to commercial purchasers. The cost of fabric has become even more ridiculous over the years. I would like information for recommendations on the best bonding for backpack construction. I've tested some retail purchase adhesives and they all lack peel strength. This is more important than with tarps. Do you have any recommendations from your own testing? ...

@tridrles4 years ago I'm surprised you didn't; do a test with just the adhesives... no sewing. I have found that where ever there is a hole (stitch) it is a weak area and will fail from there. I haven't made a DCF piece by sewing since my first one. That was 5 years ago and 10 items made. ... 1

@willek13352 years ago Question :
I have a 9x4.3 dcf tarp of 0.51oz. Hypothetically, if I wrap a cord around each end, do you think the tarp can hold my 70 kg as a hammock? Half serious half joking. 😅

@CanadianTexaninLiguria4 years ago It seems that the fabric failed - not the tie outs

@nedanother93822 years ago A) you don't know me , your video was like a pop up porn site....or how much my pack weighs. I hardly even weigh it (25ozs)....damn know it all ultralighters
Clearly you are showing off your Youtube Doctoral degree in ghetto engineering and sciency things. Your high tech measuring devices are just not available to the common man (I only have like half a 2 x 4 in my garage).
Interesting info though. Somehow when they say "bonded seams" I imagined they were heat bonded like nylon. I'm desperately tempted to make my own tarp and bug net.
Very good stuff, thanks for taking the time. ...
