Document Type and Number:
WIPO Patent Application WO/2022/080951
Kind Code:
A1
Abstract:
The present invention relates to a method for manufacturing a heterogeneous composite material thin plate, and a heterogeneous composite material thin plate manufactured thereby, the method comprising the steps of: (a) manufacturing a composite powder by ball milling an aluminum or aluminum alloy powder and a carbon nanotube powder; (b) manufacturing a multilayer billet comprising the composite powder, and comprising a core layer and two or more shell layers that encompass the core layer, the core layer being formed of the composite powder or an aluminum alloy, the shell layers excluding the outermost shell layer and being formed of the composite powder, and the outermost shell layer being formed of (i) an aluminum or aluminum alloy powder or (ii) the composite powder; (c) manufacturing an extruded material by extruding the multilayer billet; and (d) rolling the extruded material to mold same into a thin plate shape.
