Correct, not from centrifugal force.

Think about it- the clutch disk is "clamped" in place by the pressure plate.
This greatly reduces the effect of centrifugal force.

There's the disconnect. The damage you described was caused by too much
torque (rotational force) on the clutch friction plate. It was not from
centrifugal or centripetal force.
