Abstract
The invention encompasses a friction-in-oil device having a plurality of coaxial disks comprising metal rotor or driving disks, metal stator or driven disks, and loose disks of carbon/carbon ('C/C') composite material, each loose C/C disk lying between a metal rotor or driving disk and a metal stator or driven disk. Each loose C/C disk is centered by a bearing surface formed in an adjacent metal rotor or stator disk, which bearing surface has passages for feeding oil to the interface between the loose C/C disk and the metal rotor or stator disk.
