absolutely, understand all that. but small particle reinforcing, to my
incomplete understanding, doesn't serve well in a fatigue environment.
that is the kind of mechanism by which plastic radiators crack - great low
cycle mechanical properties, but when the load cycle gets up there,
fatigue romps away. i would therefore expect timing belt fiber, given
that it's subject to considerable repetitive strain many times that of
traditional small particle reinforced plastics, to have the most coherent
microstructure possible - no fillers. but i'm guessing.
