Not specifically, but is this aspect related to the article on Ductal advanced concrete mentioned way back, on the effect of including microfibers like PVA(!).
Apparently a degree of toughness is acquired by the energy being absorbed by the fibers slipping slightly in the matrix. I was surprised by the inclusion of what I would have thought of as a weak fiber in the matrix should increase the toughness. But there, of course, the problem is brittleness of the cement component, whereas with E/G the function of the epoxy is as an adhesive.
But am I overlooking the fact that fully cured epoxy might actually be quite brittle, a situation that may not have been achieved yet.
It's like doing jigsaw puzzles in the dark.
Enjoy today's problems, for tomorrow's may be worse.
