Abstract：

This　study　explores　material　modification　utilizing　molybdenum　disulfide　and　glass　fiber　as　lubricating　and　reinforcing　modified　materials　respectively.　The　specimens　underwent　tests　for　mechanical-physical　properties,　oil　storage　capacity　and　frictional　characteristics.　The　differential　analysis　identified　the　optimal　mechanical-physical　properties　of　the　porous　composite　PI　material　at　a　molding　pressure　of　192　MPa,　molding　temperature　of　330°C,　9%　of　AC　foaming　agent　content,　8%　of　molybdenum　disulfide　content,　and　20%　of　glass　fiber　content.　The　wear　coefficient　increased　with　load　and　decreased　with　rotational　speed,　indicating　the　suitability　of　this　porous　composite　oil-retaining　PI　material　for　medium-high-speed　and　low-load　frictional　conditions.　©　Published　under　licence　by　IOP　Publishing　Ltd.
