Abstract
A thin-walled hollow cylinder is made from fiber-reinforced plastics material, the cylinder wall of which is composed of at least one layer having fibers with at least one oriented direction of the fibers, and the total wall thickness d lying in the range from 10 to 1000 &mgr;m, and the ratio d /D being≦0.0025. The oriented direction(s) of the fibers are selected depending on the intended final application. Examples include, inter alia, multi-layer laminates made from carbon/epoxy, used for the production of a cylinder of this nature, having at least one layer with an oriented direction of the fibers which is parallel or perpendicular to the longitudinal axis of the cylinder.
