Abstract
Method for potting or casting hollow fiber bundles and form a tube sheet as part of fabricating a gas separation membrane module. A hollow fiber bundle is placed in a mold, into which a resin filled with solids injected, and the resin is exposed in a liquid bath in which the mold is immersed, to an ultrasonic field while it is so injected. The solids may be chosen among metals, metal oxides, silica, quartz, ceramics and inorganic salts.
