Abstract
To reduce deformation of the piston pin for the rotating connection of a ton and a connecting rod in a piston cylinder system, especially in internal combustion engines, where the piston pin is made of fiber-reinforced composite material in which fibers running in different directions are placed, it is proposed that the piston pin is secured against rotation around its longitudinal axis in the piston or in the connecting rod, and has first regions in which the fibers are arranged in planes parallel to the piston pin axis and when secured against rotation in the piston, running parallel to the piston axis, or when secured against rotation in the connecting rod, running parallel to the connecting rod axis, so that they have a component running parallel to the piston axis or to the connecting rod axis.
