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.
