  • Carbon reinforcements, in particular for use in carbon-fiber reinforced materials, and a method of generating internal protection against oxidation in carbon reinforcements
    Patent number: 6699589
    Abstract: In carbon reinforcements, in particular when used in carbon-fiber reinforced materials, sulfur-complex forming substances are chemically adsorbed, at least in part, at potential oxidation locations of an hexagonal carbon lattice to provide internal protection against oxidation.
    Type: Grant

  • Tribo-system
    Patent number: 6020072
    Abstract: A tribo-system comprises a first structural component part and a second structural component part which are in dry frictional contact with one another, each through a surface layer. For this purpose, the surface layer of the first structural component part is based on oxides or mixed oxides in monoclinic, triclinic or tetragonal crystal structure formed from MeO.sub.6 octahedrons with planar oxygen defects.
    Type: Grant
