Abstract
The composite material for a metal gasket includes a metal plate; a rubber layer fixed on the surface of the metal plate; and a solid lubricant layer fixed on the rubber layer. The solid lubricant layer contains polytetrafluoroethylene and a resin as main components, and has a friction coefficient equal to 0.15 or lower. Thus, the seal durability of the metal gasket is improved by effectively preventing fretting wear.
