elongation factor for tubular webbing

by MoapaPk » Sun Jul 25, 2010 4:24 am

I'd like a pointer to some specs on climb-spec tubular webbing.

Specifically, I'd like to know the elongation factor at (say)

10% of the breaking strength
100% of the breaking strength.


That is, the fraction the webbing stretches (from the initial length) at the specified conditions. I'm not sure if this is the proper term, but I think I can get what I want from any data on stretch under force.

Thanks.

This is an interesting recent DMM test video that may assist in your knowledge quest along with these figures.

This Test may be of help as well.

Hope that this helps.

Thanks -- that is, in fact, why I wanted the independent elongation numbers. From those videos and results, I back calculate that the elongation on breaking (for tubular webbing) is about 5%. I wanted to see if that was consistent with actual measurements of webbing stretch.

I have done some independent but not rigorous tests and see way more than 5%, probably 10+, in the webbing I use before failure. Sorry I don't have numbers, I never had a need to measure. I was just interested in checking the strength of my stitching.
