Abstract:
A process for preparing a separator cartridge, comprising:forming a cylindrical prepreg assembly, by:forming a cylindrically-shaped reinforced plastic prepreg, said reinforced plastic prepreg including an inner first major surface and an outer second major surface;contacting and adhering the inner first major surface of the reinforced plastic prepreg to a cylindrically shaped first nonwoven polymer layer; andcontacting and adhering a second nonwoven polymer layer to the outer second major surface of the reinforced plastic prepreg;forming a polymeric screen having a cylindrical configuration, said cylindrical polymeric screen having an inner diameter greater than the outer diameter of the cylindrical prepreg assembly;axially inserting the cylindrical prepreg assembly into the cylindrical polymeric screen; radially expanding the cylindrical prepreg assembly so as to cause the second nonwoven polymer layer to contact and frictionally engage the inner cylindrical surface of the cylindrical polymeric screen; andcuring the reinforced plastic prepreg.
