Aluminium (Al) based composites containing vapor-growth carbon fibers (VGCF) and carbon nanotubes (CNT) are fabricated by spark plasma sintering (SPS) in this paper. The thermal conductivity of the composite is three times higher than that of Al material. The composite materials will be able to use as a radiation fin of a heat exchanger and a heatsink. To apply the composites to real used conditions, the strengths and thermal conductivities at several temperatures of the composites should be clarified experimentally. In this paper, therefore, pure tensile tests and laser flash methods are conducted to clarify strength and thermal conductivity of the composites at several temperatures. According to the experimental result, the composite has the different thermal effect on the strength from pure Al. And then the composite has better thermal conductivity than pure Al at high temperature.
