A molding process of aluminum foams by using a rotating mold is proposed in order to improve the mold filling and forming process for light-weight parts of vehicles. Aluminum powder mixed with a foaming agent is extruded into the mold through the die heated to a temperature higher than the melting point, and the mold is filled with the aluminum foam. When the diameter of a cylindrical mold is large, the influence of gravity is significant and the mold is not filled successfully. In the proposed molding, the aluminum foam is extruded into the rotating mold of large diameter and the volumetric ratio of foam to mold cavity is improved. However, the effect of the mold rotation on the mold filling is limited due to friction.

General Standard

Compared with the traditional metal square cabin, the new type square cabin makes a good performance on lightweight and can also improve the stiffness of the structure. Both the static and dynamic analysis results which tested under the condition of general standard show that: the new type cabin which made by aluminum foam sandwich composite panels can reach the purpose of light weight design and also can improve the stiffness of the structure. What is more, optimum design is used on the dimension parameter to enhance the property of the square cabin.

Superior Property

Aluminum foam is porous material and it is superior property which is light weight , absorption sound, heat insulation and energy absorption than other materials. In present the panel of aluminum foam sandwich panel to use as structural materials is adhered with adhesive or wax for adhesion. The aim of this study is to clarify producing conditions to make sandwich panel by melt drag process. Melt drag process is single roll strip casting process. Producing aluminum alloy strip and adhering foam are at a time.

Light weight materials which possess high strength and durability are being utilized by the automotive industry to increase fuel economy. Rapidly solidified (RS) Al alloys are currently being extensively studied for this purpose. In this investigation the microstructure of an extruded Al-8Fe-2Mo alloy, produced by Pratt & Whitney Aircraft, Goverment Products Div. was examined in a JE0L 2000FX AEM. Both electropolished thin sections, and extraction replicas were examined to characterize this material. The consolidation procedure for producing this material included a 9:1 extrusion at 340°C followed by a 16:1 extrusion at 400°C, utilizing RS powders which have also been characterized utilizing electron microscopy.
