無潤滑複合摺動部材の製造方法によって達成される。According to the present invention, a non-lubricated composite material is produced by embedding a foamed polystyrene resin in a sand mold and casting an alloy with good sliding properties, such as a copper alloy, according to the present invention. In this method of manufacturing a sliding member, first, a graphite member having a trapezoidal cross section is attached to the foamed polystyrene resin formed into the above-mentioned cast member shape to prevent removal after manufacturing and molding. A notch part for arranging multiple pieces at an angle of 75 degrees and a notch part for fitting the fixing fittings of the graphite member are provided, and then the graphite member is placed in this notch part, and the fixing fittings of the graphite member are fitted. After fitting, the graphite member and the styrofoam resin fitted with the fixing fittings for the graphite member are embedded and molded in a sand mold.
This is achieved by a method for manufacturing a non-lubricated composite sliding member, which is characterized by casting a copper-based alloy and casting the graphite member in a fixed arrangement state.
