Greg, not familiar with that material, but wouldn't be concerned with or without it on a longbow. Glass or selfbow.
Nock transition, angle, more important. Narrow, thicker tips, along with less stress, preload, as with a recurve bow.
Also building string loops, pad,reinforce so load is even thru the nocks.
Shooting proper weight arrows, also!
High performance strings don't kill bows, people do!
