Method of constructing a fiber-reinforced piston for internal combustion engines

摘要

A fiber-reinforced piston for internal combustion engines, comprising a molded body of inorganic fiber forming a top land and a ring region of the piston. The molded body has a content of granulated fiber having larger particles of a particle diameter less than 100 mesh in an amount of not more than 10 weight percent with respect to the total amount of fiber used, and a light alloy matrix fills and is combined with the molded body of inorganic fiber.
