ABSTRACT:
A porous polymeric bearing is formed of a sintered composite of polyphenylene sulfide and a cured condensation thermosetting resin such as a phenolic compound wherein the presence of the thermoset material affords structural support during the sintering of the polyphenylene sulfide and further induces highly interconnected porosity in the fabricated composite adaptable for impregnation with a liquid lubricant. The fabrication includes a curing and degassing of the compressed greenware bearing followed by sintering and a subsequent post cure.
