Preform structures, composite aluminium or aluminium alloy components composited with preform structures and methods for producing these
 A method is provided for producing a preform structure which is used in a composite aluminium or aluminium alloy component in which a base metal of an aluminium or aluminium alloy is reinforced with reinforcing materials. A slurry is prepared by mixing reinforcing materials including ceramic particles and first whiskers with burning-away powders and liquid. Liquid components contained in the slurry are filtered to provide a dehydrated structure. Thereafter a preform structure is produced by sintering the ceramic particles with the first whiskers after burning the burning-away powders in the dehydrated structure.
