A centrifuge basket shell formed by winding fiber-reinforced resin tape in a helical pattern over a thin shell plate which contains a plurality of holes for the passage of liquid therethrough, perforations being formed in the helix pattern of the wound tape by means of respective hollow ferrules connected rigidly to a cylindrical part of the shell plate, so as to enable liquid which passes through said holes in the shell plate to pass also through the helices of wound tape without increasing the stresses induced therein by rotation.
