Yes. Thinking maybe ILF limbs may use G10. Although hard on tools.
Using G-10 for a wedge will work ok, but its going to be much stiffer than a typical hardwood wedge, and will most likely effect your working limb length. This could be a good thing, or bad depending on your limb design. I think it will increase your draw weight vs std hardwood wedges too.
But.....Its too damned expensive to use as a wedge. IMO.

I think that might depend on the length and thickness of your wedge, as well as the taper rate. I personally prefer a longer lean wedge. My typical wedge dimension going into the form is 12" long and about .30-.32 at the butt tapered to nothing. I use different stops for long limbs vs medium lengths. (1" difference) 24" limb vs a 25" length.
What this does is keep the fade location, and working limb lengths the same, which results in more consistent performance between the two. I also have marks on the form where I cut the limb butts off giving me either a 11" finished wedge, or 10" finished wedge length. By keeping the tip notches in the same location, this changes the working limb length and can be used for building draw length specific bows on both ends of the spectrum, getting higher performance for shorter draw length, and a smoother draw for longer draw lengths.
To answer your question regarding a hinge effect.... Yes, it could cause a hinge effect depending on the draw weight, taper rates used, and limb length. It Definitely pushes the working limb out further towards the tips.
But with that being said, I believe that if a guy were to play with using power wedges made from G-10, instead of standard wedges, you could come up with an excellent bending wedge that would be very consistent.
I have build many bows using 2 power lams instead of a solid wedge with excellent results. The last one I did like that I used 2 black walnut PW's at .130 to nothing in 12" and ran stable core through the center.
I just built a second set of limbs for this bow and matched the power wedge configuration.

If a guy was to use G-10 for one of the power lams in a two power lam lay up like this it could prove to be interesting.
