These two samples were subjected to the same ASTM impact test. I forgot to ask the test number.  Chippy organized the test.

The Vectran clearly outperformed the Kevlar.  Did I mention that Chippy sells Vectran?  Odd twist, he doesn’t believe in websites nor email.  Have to use a phone to contact him.  425-747-8712.  And I have rarely met anyone who could be creating better topics for how-to videos than Chippy.
