ABSTRACT:
A system for use in papermaking including at least two members one of which is movable relative to the other and in frictional engagement therewith wherein at least one of the members comprises an elongated flexible composite including a plurality of ceramic segments, each segment having at least two opposite surfaces that are flat and parallel. The segments are aligned in stacked relationship with their flat faces in abutting face-to-face relation and forced toward each other in the direction of their composite length with a force which is sufficient to maintain the segments in compression when subjected to conditions of thermal change and/or flexing of the member during use. The ceramic member is provided with a smooth elongated working surface which defines an area of contact between the members of the system. Systems including a papermaking foil or suction device in a papermaking process, or a doctor blade are disclosed. A method for making the ceramic member is disclosed.
