    Abstract: Milled silica or alumina fibres or whiskers are formed into a reinforcement for a squeeze cast article such as a piston for an internal combustion engine. The problem of handling the milled fibres or whiskers while they are formed into the reinforcement is mitigated or overcome by the use of coagulated latex to bind the milled fibres or whiskers in a colloidal silica solution until they are fired to form the reinforcement. In addition, a starch is used to prevent the milled fibres or whiskers settling when in the colloidal silica solution.

    Abstract: A method of manufacturing a piston for hydrostatic axial and radial piston machines by non-machining forming, by filling a material that is in a substantially unresistant, formable state into a mold defining a piston outer contour which is closed on all sides, in which at least one supporting core is arranged spaced from the inner contour of the mold to remain in the completed piston to define a core region in the interior of the piston that is closed on all sides, then solidifying the material forming a piston with high strength characteristics and low weight, and removing the completed piston with the enclosed supporting core. The invention also comprises a piston for a hydrostatic axial or radial piston machine, made integrally of high-strength material in a non-machining forming process, such as by casting, sintering or the like, having in its interior at least one core region surrounded by the high-strength material and containing a supporting core that is provided to take up forces acting on the piston when in operation and which, during formation of the piston defines the core region, which supporting core is lighter than the high-strength material it replaces in the core region.

    Abstract: The invention is an improvement in a lightweight carbon-carbon composite piston, the improvement comprehending the use of near-net shape knitted or warp-interlock pre-forms to improve the structural qualitites of the piston. In its preferred embodiment, a one piece, tubular, closed-ended, knitted pre-form (a sock) of carbon fibers (11) embedded within the matrix of the piston structure forms the crown (12), side wall (15), skirt (16) and inner surface (18) of the piston, and wrap-interlock pre-forms strengthen the piston crown and wrist pin bosses.

    Abstract: A method of manufacturing a piston of an internal combustion engine includes holding a soluble core to a plurality of first projection portions and a plurality of second projection portions and a plurality of third projection portions formed in a pair of straight portions of a strut member for preventing thermal expansion of the piston. The first projections have a bent portion bent outwardly so as to be along an inner face of the soluble core and the second projection portions have a curved holding portion bent inwardly so as to be along a lower surface and inner surface of the soluble core. By holding the strut member and the soluble core in the piston, the soluble core is melted away and an oil-cooling gallery is formed by pouring water into the mold.
