1. A method for preparing a bearing comprising:
a. supplying a bearing having a first surface and second surface, wherein said first and second surfaces are configured to slide against one another;
b. providing a bearing liner having a first bonding side and a second sliding side, wherein said bearing liner comprises woven or non-woven fabric having a thickness of 0.005 inches to 0.030 inches, a basis weight of 5.0 grams/ft2 to 70 grams/ft2 and an initial airflow permeability of 1 cfm to 100 cfm as measured by ASTM D737 (2018);
c. applying a first bonding side resin composition containing polymerizable resin including glass and/or carbon fibers to said bonding side of said liner and partially polymerizing;
d. applying a second sliding side resin composition containing polymerizable resin to said second sliding side of said bearing liner and partially polymerizing, wherein said second sliding side resin composition includes a lubricant at a level of 1.0% (wt.) to 60.0% (wt.);
e. applying said first bonding side of said bearing liner containing partially polymerizable resin to one of said first or second surfaces of said bearing and bonding said first bonding side of said bearing liner to said first or second bearing surfaces.
