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.

Silicon carbide-reinforced light alloy composite material

A method for controlling the orientation of short fibers in a short fiber shaped article of composite materials, wherein the short fiber article shaped from a mixture of short fibers and solvent is subjected to a drawing treatment to control the average angle of orientation of the short fibers according to a draw ratio.

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&lt;I(c) x).

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 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.

Method of constructing a fiber-reinforced piston for internal combustion

A method of producing a fiber reinforced composite article comprising forming a shaped fiber body of predetermined configuration from inorganic fibers, placing a tubular member in the shaped fiber body, the tubular member having an opened end and a plurality of communication ports therein and charging a molten matrix alloy by squeeze casting from the outside of the shaped fiber body and, additionally, from the inside of the shaped fiber body through the tubular member. The article can be a connecting rod of an internal combustion engine and the shaped fiber body can be located at a position corresponding to a rib for reinforcing the connecting rod.

Method of producing a fiber-reinforced composite article

A connecting rod for an internal combustion engine comprising a rod body having a fiber bundle reinforcement integrated therein. The fiber bundle reinforcement extends longitudinally in a central rod portion of the connecting rod and is exposed at the peripheral surface at a small end portion of the rod where a bore is provided for connection with a piston pin. The fiber bundle reinforcement is exposed in the region of the bore adjacent the central rod portion.

A process for producing fiber-reinforced magnesium alloy materials with improved mechanical properties which includes the steps of placing a shaped article of silicon carbide whiskers or silica type, alumina type or silica-alumina type fibers in a casting mold, and pouring into the mold a molten matrix of a magnesium alloy at a temperature lower than 800.degree. C. The shaped article is impregnated with the molten matrix by means of a high pressure coagulation casting method while maintaining the original configuration of the shaped article to form a composite. A magnesium-silicon compound and/or a magnesium-aluminum compound are precipitated in the matrix at the filling and composite-forming step by reaction between the surface fibers of the shaped article and the molten matrix. The whiskers or fibers may be covered by a film of copper, nickel or silver to vary the amount of the precipitated compounds.
