ABSTRACT:
A ceramic tubesheet pierced by a plurality of hollow, glass fibers and consisting of sintered particles is rendered essentially impermeable by selectively fusing the portion of the tubesheet subjacent to and defining one of its surfaces. The fiber lengths extending from the opposite surface of the tubesheet are freer to flex and less likely to be broken than if the entire tubesheet were fused.
