I
believe in the beginning graphite fiber was made from Rayon a Cellulose
based fiber and I’m sure for some application it’s stilled used. I believe
Mitsubishi Rayon started as a joint venture with Dupont and now the polymer of
choice is polyacrylonitrile. (Also a development of DuPont)

David,
I checked the web site you posted. Here's what I come up with:
Mitsubishi Rayon is not a material; it is a company, a division of the
Mitsubishi company -- or, more likely, a wholly owned subsidiary.
One of their products is carbon fiber. They claim that their carbon fiber
is better because of the precursor material they make it from. (No, it's
probably not rayon that they make it from, but it is a fiber that we more
commonly associate with fabrics.)
The shaft is not discussed but the material and its use is. Sounds like the
application is the very standard sheet-wrapped "graphite" shaft
operation:
carbon fibers in a prepreg, and bonded together with a resin (almost
certainly epoxy in the case of golf shafts).
Hope this helps.
