摘要:
A silicon carbide-reinforced light alloy composite material comprises a matrix of a light weight alloy and a reinforcing material consisting of at least one of a silicon carbide whisker and a silicon carbide grain. In the composite material, the content of SiO.sub.2 contained in the reinforcing material, is set in the range of 0.05 to 5.0% by weight.

In a process for molding a fiber molding for a fiber-reinforced composite material with short fibers oriented in one direction, a slurry molding material having short fibers dispersed in a liquid is used, and pressing forces are applied to the molding material from two directions substantially perpendicular to each other within a mold, while removing the liquid.

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.

A membrane-electrode assembly for a solid polymer electrolyte fuel cell includes a proton-conductive composite membrane including a reinforcing sheet and an electrolyte membrane. The reinforcing sheet has through-holes extending in a thickness direction of the reinforcing sheet. The through-holes are provided in a portion other than an edge of the reinforcing sheet in an in-plane direction. An anode electrode layer is provided on one surface of the proton-conductive composite membrane. A cathode electrode layer is provided on another surface of the proton-conductive composite membrane. At least one of an edge of the anode electrode layer and an edge of the cathode electrode layer in the in-plane direction is arranged outside in the in-plane direction with respect to the portion in which the plurality of through-holes are provided.

摘要:
A method of producing a fiber-reinforced composite material in which a fiber body is mounted on mounting surfaces in a mold cavity, which mounting surfaces are in fluid communication with the outside of the mold through air relief passages. A molten matrix metal is poured into the mold cavity and then subjected to a high hydrostatic pressure so as to be filled into the fiber body while expelling the air from the fiber body to the outside of the mold through the air relief passages. The molten metal is thereafter filled into the air relief passages and solidifies immediately to seal the mold cavity from the ambient atmosphere whereby the molten matrix in the mold cavity is rapidly solidified under high pressure to form a fiber-reinforced composite material of high quality with inclusion of substantially reduced voids or cavities.
摘要:
Method of making a cast reinforced article, such as a connecting rod which includes preparing a bundle of uni-directional inorganic fibers, at least some of which are metallic or metal coated by placing the bundle into a shaping container and heating it to partially fuse the metallic or metal coated fibers to each other. The partially fused bundle is positioned in a mold with a fixed minimum gap surrounding it. A molten light metal alloy is squeeze cast into the mold forming a matrix of the alloy and the bundle. In the case of a connecting rod, the bundle should be shaped elliptically and positioned in the mold such that (I(c) y
