ABSTRACT:
A method for fabricating a self-lubricating foil-type material having a low frictional coefficient from a stack of an expanded-metal sheet and at least one polytetrafluoroethylene (PTFE) strip by compression and heating. The stack is first calendered and then the calendered stack is heated to sinter the PTFE.
