Abstract
A porous aluminum body having high porosity and a manufacturing method therefor are provided, wherein the porous aluminum body can be manufactured by continuous manufacturing steps. In the present invention, this porous aluminum body includes a plurality of aluminum fibers connected to each other. The aluminum fibers each have a plurality of columnar protrusions formed at intervals on an outer peripheral surface of the aluminum fibers, the columnar protrusions protruding outward from the outer peripheral surface. Adjacent aluminum fibers are integrated with the aluminum fibers and the columnar protrusions.

A method for manufacturing a porous aluminum body comprising:
- adhering titanium powder and/or titanium hydride powder to an outer peripheral surface of aluminum fibers to obtain a mixture and sintering the mixture at a temperature in the range of 655° C. to 665° C. in an inert gas atmosphere.
The method for manufacturing a porous aluminum body comprising:
- adding a titanium powder and/or a titanium hydride powder to a member of the group consisting of:
- aluminum fibers and a mixture of aluminum fibers and aluminum powder;
- followed by mixing to obtain a mixture;
- spreading the mixture on a carbon sole plate or in a carbon container in a predetermined shape;
- and then sintering the spread mixture.
A method for manufacturing a porous aluminum body, wherein the porous aluminum body comprises a plurality of sintered fibers, and the aluminum fibers each have a plurality of columnar protrusions protruding outward from an outer peripheral surface of the aluminum fibers and are integrated with the aluminum fibers and the columnar protrusions, the aluminum fibers each having a wire diameter of 40 to 300 um and the columnar protrusions each having a smaller diameter than the aluminum fibers,
- the method comprising:
- adhering titanium powder and/or titanium hydride powder to an outer peripheral surface of aluminum fibers to obtain a mixture and sintering the mixture at a temperature in the range of 655° C. to 665° C. in an inert gas atmosphere.
