Does anyone know if the addition of kevlar fibre makes fins stronger?
We all know that it's used in bulletproof vests but they're subjected to very different forces to fins.
 
I'm not sure but i have a feeling that Picasso used this years ago in some Black Team fins!
I can't vouch for this but it does ring a bell.
 
I use Specialfins hybrids which contain some kevlar. A few other brands put it in too. I was wondering if it adds anything of value to the fins or is it just a gimmick.
 
Kevlar withstands higher elongation - it is not as fragile as carbon.
Kevlar is the hardest to work with material. You need a special scissors to cut it.

The blade doesn't gain performance. Just another marketing attempt.
 
The new 2010 Picasso catalog includes a new kevlar/carbon blade, the Diablo, so somebody thinks they work (at least I hope they think so)

I'm pretty sure DiveR blades are mainly kevlar. Though I doubt this improves peformance, they do have a reputation for being very durable.
 
Specialfin Hybrids have a center of carbon fiber and an outer layer of kevlar. As explained to me, the kevlar is there to protect the carbon, not to add performance.
