Abstract: A method for preparing foamed aluminum alloy composites comprising the steps of: (a) placing a liquid hardness-reinforcement composition into a tank, the hardness-reinforcement composition containing about 54.about.64 wt. % of an inorganic powder, about 35.about.45 wt. % of a nonflammable curable resin, and about 1 wt. % of a curing agent; (b) placing a foamed aluminum alloy plate having an internal porous body into the tank containing the hardness-reinforcement composition, then applying a pressure of about 10.about.50 Kg/cm.sup.2 onto the foamed aluminum alloy plate for about one to two hours so as to allow the hardness-reinforcement composition to soak into the foamed aluminum alloy plate and form a coated layer on the surface of the porous body; (c) removing the foamed aluminum alloy plate that has been coated with a layer of the hardness-reinforcement composition from the tank; and (d) drying and curing the curable nonflammable resin so as to form the foamed aluminum alloy composite.
