Definitions

  • the invention is based on the preamble of claim 1 from JP-A-60182338.
  • the invention has for its object to show a fiber reinforcement for a light metal cylinder, which on the one hand results in a predetermined reduction in the thermal expansion of the cylinder with a predetermined reduced heat transfer.
  • the volume fraction of the short fiber based on the cylinder can be up to 40% in an embodiment of the invention.
  • the molded part on the outer circumference can be equipped, at least in regions, with a winding layer of another long fiber. Measures to reduce the radial thermal expansion of a cylinder or cylinder tube are per se, for. B. from DE-C-31 34 771 known, a metallic cylinder tube is surrounded on the outside by a winding bandage made of a fiber composite material. This complex design is advantageously avoided with the winding layer integrated into the fiber molding according to the invention.
  • a fiber molded part designed according to the invention which significantly reduces the spatial thermal expansion of the cylinder when the heat transfer is desired to be small, is advantageous both for the individual production of light metal cylinders and for a composite construction of several cylinders in an internal combustion engine housing.
  • a fiber-reinforced light metal cylinder 1 for an internal combustion engine (not shown) comprises, in the material composite with the light metal 2, a tubular fiber molded part 4 made of short fibers 3.
  • the fiber molded part 4 contains separate long fibers 6 in an arrangement essentially parallel to the cylinder axis. Furthermore, the fiber molded part 4 is on the outer circumference in the area adjacent to the firing zone of the cylinder 1 equipped with a winding layer 7 of a further long fiber 8.
  • the short fibers 3 are made of ceramic material.
  • a volume fraction related to cylinder 1 can be up to 40%.
  • the long fibers 6 In order to reduce the thermal expansion of the cylinder 1 in the direction of the cylinder axis 5, the long fibers 6 have a coefficient of thermal expansion which is substantially lower than that of the light metal.
  • Winding layer 7 are also made of high-strength material and serve to reduce the thermal expansion of the cylinder 1 in the radial direction.
  • the cylinder 1 can be formed either individually or in combination with a machine housing, the composite material of light metal 2 and fiber molded part 4 being achieved by die casting. To further increase the cylinder 1, which is preferably used for an internal combustion engine, it can be recompressed with the winding layer 7 during die casting in its cylinder section facing a combustion zone.
