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.

A method for fabricating a self-lubricating foil-type material, comprising:
- contacting an expanded-metal sheet and at least one polytetrafluoroethylene (PTFE) strip to form a stack;
- calendering said stack to at least partially crush said expanded-metal sheet;
- and
- heating the calendered stack to sinter said PTFE, thereby forming said foil-type material.

A method for fabricating a self-lubricating foil-type material, comprising:
- contacting an expanded-metal sheet and at least one polytetrafluoroethylene (PTFE) strip to form a stack;
- calendering said stack at a pressure of greater than 200 kg/cm.sup.2 to at least partially crush said expanded-metal sheet;
- and
- heating the calendered stack to sinter said PTFE, thereby forming said foil-type material.
