Abstract
A composite material composed of nanocarbon materials and metallic materials for a matrix is extrusion molded to have the nanocarbon materials oriented in one direction.
Claims5
A process for manufacturing a nanocarbon-metal composite material, comprising the steps of:
- mixing nanocarbon materials and metallic materials for a matrix;
- compressing their mixture to form a compact;
- covering the compact by a material having a melting point higher than that of the metallic materials;
- heating the covered compact in an inert or non-oxidizing gas atmosphere to a temperature in the temperature range in which the solid and liquid phases of the metallic materials can coexist;
- applying pressure to the heated compact to form a primary molded product by plastic deformation;
- and
- extrusion molding the primary molded product to produce a nanocarbon-metal composite material.
