Abstract

1. A composite compacting cylinder, comprising a shaft and a case (2) which is an interference fit on said shaft, said case (2) being itself composite and comprising a first outer layer (3) of a first material A, a second inner layer (4) of a second material B, the materials of said two layers being metallurgically bonded together prior to the mounting of the case on the shaft, characterized in that the second material B has a coefficient of linear expansion which is higher than that of the material A, so as to pre-stress the material A in compression prior to the mounting of the case on the shaft, the value of this compression pre-stressing being at least equal to the tensile stress produced when the composite case is mounted on the shaft.
