My initial expectation was that it'd be due to the resin breaking down over time due to exposure to oil and exacerbated by the heat and heat cycling (ignorance warning: I assume things that breakdown from petroleum-based oil, would do so with synthetics, too...)
Hah... And he just covered the resin issue while typing!
Followed by the assumption that CF wouldn't be as good at sudden, massive compression loads like a conn rod would see.
So to hear its fiction wear being the issue, is surprising, as if have envisioned most CF parts to incorporate metal bearings or surfaces at those junctions. After all, our conn rods have bearings, they're not directly contacting the crank since even with lube there's wearing going on. (and the bearing being easier/cheaper to replace than an entire rod)
As an example, an intake valve being CF, would be given a steel interface at the rocker arm. Whether that's an insert added before resin is applied (therefore being anchored), or something more simple like a cap, might come down to the specific part getting remade in CF.
