Abstract: A method for manufacturing a connection for composite tubing is disclosed. The method includes maintaining tension on the composite fibers while “winding in” the connector to the composite tubing. The tension on the fibers results in the fibers bridging across traps of the connector as they are being wound. The bridging results in improved load bearing characteristics of the connection.

Abstract: A non-woven fabric liner comprising a plurality of bonded fibers is attached to the inner surface of one of the upper and lower shells of a disk cartridge. A main body of the fabric liner lies against the inner surface of the shell and is spaced a predetermined distance from a corresponding surface of the storage media within the cartridge. A region of the fabric liner is subjected to a fuzzing process in which the bonded fibers in that region are loosened to form a region of upstanding fibers that extend from the main body of the liner to the surface of the disk. The upstanding fibers wipe the surface of the disk while the main body of the liner remains spaced from the disk, thereby reducing drag.
