Strongest Locked Brummel Splice Measurement Poll

[Liam88]

I'm doing some research on the Locked Brummel splice for my dissertation. Thought I'd make some fun of it and get a poll going (if it works). It will be interesting to see what splicing knowledge is out there.

 

These are just some of the treatments used in my project - the supposedly stronger ones anyway. There are 3 samples per treatment. All spliced the same apart from the bury and taper lengths altered. Rope is 10mm tenex-tec (hollow braid). Splices will be tested to destruction and measured in kg.

 

So which splice is the strongest?

 

Picture shows the splices in question from top to bottom: 10 rope diameter bury (d), 15d, and 20d (of which 25%, 50%, 75% taper for each one).

 

Results to come no more than 2 weeks time. Please feel free to ask any questions. If you could justify your decision as well that would be great.

 

(Please note this is purely for research purposes only and the results should not be adopted as splicing guidance)

Interesting project (well more interesting than mine but I guess the grass is always greener).

 

Are you predicting the failure mode to be fibre breaking or pullout (I guess you might get lucky and get both)? Either way, I suspect that any strength gains will plateau past a given point...

I suspect that any strength gains will plateau past a given point...

 

Right on the money there, but at which measurement will it be?

 

Another challenge: could you rank them in order of strength and justify it?

Personally i think they will all be similar.

I believe they will all break at the end of the taper.

Personally i would of gone for a longer or certainly smoother taper

but look forward to the results if i ever notice them.

PM would be nice:thumbup:
