Embodiment Construction

[0054] Figure 1 shows a rotary screen printing plate 10 made from a thin-walled hollow cylinder 12 according to the invention. Depending on the pattern to be printed, using high energy radiation such as CO 2 A laser makes holes in the cylinder. In this case, these apertures form a number of printing apertures 14 defining the images 16 and 18 to be printed. For example, for a cylinder with a diameter D of 203.4mm and a length L of 1850mm, the total wall thickness of the cylinder d tot is 140 μm.

[0055] figure 2 The fibers 22 (schematically represented by thinner continuous lines) on a planar layer 20 of fiber-reinforced plastic are shown aligned parallel to the longitudinal axis of the cylinder made from the layer. This axial orientation of the fibers is advantageous in reducing the overall bending of the printing plate 10 .

[0056] For the sake of simplicity, in the following figures, the same parts are denoted by the same reference numerals.

Abstract

The invention relates to a thin-walled hollow cylinder (12) made of fiber-reinforced plastic. The wall of the cylinder consists of at least one layer (20; 32, 34; 32, 44, 46) having fibers aligned in at least one direction, with a total wall thickness dtot in the range of 10 to 1000 microns, The ratio dtot / D≤0.0025. The orientation(s) of the fibers are selected according to the desired end use. Examples of such cylinders include inter alia: laminates of layers made of carbon / epoxy resin. The laminate can be used to manufacture cylinders of this type, the laminate having at least one layer in which the fibers are aligned parallel or perpendicular to the longitudinal axis of the cylinder.

Description

technical field [0001] The invention relates to thin-walled hollow cylinders made of a fiber-reinforced plastic. Background technique [0002] For example, from DE-A-2911167 a hollow cylinder with a relatively thick wall is known for use as a drive shaft. This known cylinder is a layered structure comprising at least four layers. The layer contains glass fibers or carbon fibers aligned at a defined angle to the longitudinal axis of the shaft. According to this patent publication, the innermost layer having an orientation angle of glass fibers of ±30° to ±50° is the main support for absorbing the shear load. The function of the first intermediate layer with the orientation angle of glass fibers from 0° to ±15° is to increase the wall thickness so as to resist twisting during use. Another intermediate layer comprising carbon fibers aligned at an orientation angle of 0° to 15° is used to increase the stiffness of the shaft in order to dampen the usual...
