Fiber reinforced ceramic matrix composite piston ring |
摘要 |
A heat-resistant, thermally stable, ductile piston ring for an internal combustion engine having a structure comprised at least partially of fiber reinforced ceramic matrix composite (FRCMC) material. The FRCMC material includes a polymer-derived ceramic resin in its ceramic state and fibers. The ceramic portion of the material for the most part provides the heat-resistance of the FRCMC material, while the fibers produce a desired degree of ductility in the FRCMC material. Filler materials may incorporated into the piston ring to produce the desired degree of hardness and/or coefficient of friction.
