A method is provided for designing and producing fiber-reinforced polymer (FRP) pistons. Pistons made with FRP have a lower mass than prior art metal pistons conferring advantageous engine efficiency and stability. FRP pistons also increase the thermal efficiency of engines by having a lower thermal conductivity, with tighter piston-to-bore clearance, and/increased air-fuel ratio than pistons of metal. The technical parameters of the piston are identified, and a piston body blank is produced. The blank is then machined, a bearing surface for the pin bore is created, the piston blank is optionally coated, is optionally subjected to Heavy Metal Ion Implantation (HMII) treatment and is subjected to sodium silicate impregnation to produce the final pistons.

A piston that moves reciprocally in the cylinder of an internal combustion engine and has a piston skirt that makes sliding contact with the inner wall of the cylinder. Solid lubrication parts are provided on the sliding-contact surface of the piston skirt. The solid lubrication parts include at least one type of silver, silver alloy, copper, or copper alloy, and at least one type of carbon material or carbide ceramics.
