Re: [RCSE] Kevlar Questions

[David A. Enete]

I use Kevlar for my HLG fuse with great success.  I just bought a second
batch of cloth and noticed that the old scraps left over are a couple shades
darker than the new kevlar.  This is, as I've read, because of breakdown
somewhere at the molecular level.  I've also heard that a layer or two of
fiber glass is supposed to prevent this breakdown.

Along another thread-line...
I found a source of Kevlar tonight in my basement.  I teach 
percussion and have for years.  During the Fall, I work with marching 
bands.  High-tension snare heads are now (for the past 13 years) made 
from woven Kevlar.  I had a bunch of old heads in the basement that 
we had replaced at the start of a season with a University drumline. 
I cut out the woven kevlar and peeled away the plastic top surface. 
Nice and lite...and free.  Of course, the pieces are just 14" round. 
Time to design a new Kevlar Frisbee!

Subject: [RCSE] Kevlar Questions


 I am considering building a H/L fuse out of Kevlar. I believe I read
 something on the list months ago, that Kevlar has a problem with ultra
 violet radiation. Anyone know what happens to the kevlar under these
 conditions?

 What about the Maple Leaf, I think that is what the all Kevlar model is
 called, dose anyone know if they use any type of UV additives to the epoxy
 or if there is any such product?

 Thanks
