Frozen Webbing Strength

[Valhallas]

I'm curious if anyone knows of any research pertaining to the strength of frozen webbing. I'm aware of the effects of sun bleaching and other summertime related strength loss issues, but haven't read anything about freezing. Presumably lots of the webbing in the Cascades that I'm sure many people rap and belay off freezes every winter and, if my limited experience is any indication, it is not all replaced each year.

 

I think the two salient questions are:

1) how does the freeze-thaw process effect the strength of unfrozen webbing?

2) how does being frozen effect the elasticity and strength of webbing?

Great questions. Anyone got the data?

I once asked this same question. Answer is on the bottom of this page: http://cascadeclimbers.com/forum/ubbthreads.php/topics/637334/3
