The manufacturing of a suitable rigid porous graphite/alumina preform has b
een investigated taking into account the influence of the binder type, the
graphite/alumina content in the preform and the percentage of binder in wat
er. The preforms showing an acceptable rigidity have been infiltrated with
a CuSn12 bronze alloy by squeeze casting considering two different pouring
temperatures. The composite quality is strongly influenced by both the grap
hite/alumina volume fractions and the binder type. The optimal quality has
been obtained by infiltrating a Carsil 2000(TM) binded preform containing 3
0 vol % graphite flakes and 70 vol % alumina fibres. (C) 1999 Kluwer Academ
