Sliding member usable in dry and wet states and method of manufacturing the member

A sliding member usable in dry and moistened states or in a state of immersion in water, comprising:

• 5 to 30 wt % of a synthetic resin coated filler powder composition obtained by polymerizing an olefinic monomer in the presence of a filler having a friction-reducing and/or wear-resisting property, wherein said resin coated filler powder composition comprises about 10 wt % to 90 wt % of said filler;
• 0 to 65 wt % of a reinforcing material;
• and
• 30 to 70% of a binder containing a waterproof synthetic resin for forming a matrix;
• wherein said filler having a friction reducing and/or wear-resisting property comprises a selection from inorganic solid lubricants including graphite, molybdenum disulfide, boron nitride, glass beads, silica beads, glass fiber powder, and carbon fiber powder, organic solid lubricants including polytetrafluoroethylene, silicone resin powder, silicone resin beads, and polyamide resin beads;
• and metal based solid lubricants including copper powder and tin powder.
