Current CMF research looks to be primarily at North Carolina State University.
Here is one of the most recent news blurbs, with a fistful of links to the previous ones. Weight is somewhere between 1/3 and 1/2 that of RHA of equal DR, which isn’t quite as good as improved ceramic IIRC, but it doesn’t shatter upon absorbing a hit. Up to you if Kessler has significant ties to that particular university.
Late Edit: The head researcher’s name - Afsaneh Rabiei - intrigued me, so I did a little digging. Turns out she did her undergraduate work in the mid-80’s (when Strange Things started happening) in Tehran, which IIRC isn’t terribly far from a Vile Vortex (the one around Mohenjo-daro). She later did her PhD work in Tokyo in the mid-90’s (when Strange Things were starting to ramp up), which isn’t terribly far from another Vile Vortex (the one around the Devil’s Sea). I personally feel this sets her up well to have experienced Something, and perhaps her research is intended to help more than just the soldiers fighting our mundane enemies...
