A piston-rod assembly with a piston rod having at least one attachment at
one end. The piston rod is fabricated of fiber reinforced composite. The
piston rod has a body of fiber-reinforced ceramic with a basic matrix of
carbon fibers or ceramic fibers or both wherein at least silicon carbide
is embedded and with an open porosity, at least at the surface layer, of
no more than 3% of the volume of that layer admitting lubricants into the
pores. The at least one attachment (2, 18a, 19, or 22) includes at least
one component of a non-ceramic material that fits into and/or interlocks
with the piston rod.
