Abstract
Sintering is used for fabrication aluminum fiber products, however this method involves considerable difficulty due to the presence of oxidized layer on the surface. On the other hand, the aluminum brazing material, which is mainly used in the fabrication of radiators for automobile, is to be sintered easily with keeping original characteristics of aluminum because its brazing layer works as binder.
In this study, investigations were carried out on fabrication aluminum fiber products by using aluminum brazing fibers produced by coiled sheet shaving, and the sintering conditions of the aluminum brazing fiber for porous products were reviewed. The results showed that at the sintering temperature of 873 K, fiber porous products with a tensile strength of 1.2 Mpa can be fabricated. In addition, by mixing aluminum brazing fibers to pure aluminum fibers, fiber porous products with parent material made of pure aluminum can be fabricated. It was also confirmed that aluminum sintered products with large porosity of 75% to 88% can be obtained by changing the mixture rate of aluminum brazing fibers.
