Composite materials are made of vapor-grown carbon fibers (VGCF) with the aluminum based matrix. Two aluminum based matrix such as pure aluminum matrix and the matrix added Al-12Si to pure aluminum are chosen for the composite materials. The thermal conductivities of the composite materials were measured by the method of leaser flash, and mechanical properties such as tensile strength and total elongation are measured by pure tensile tests. The test results show that the matrix added Al-12Si to the pure aluminum is benefit to increase the thermal conductivity of the composite materials of VGCF. The thermal conductivity of the composite material with the uniform alignment VGCF is higher than that with the random alignment of the VGCF. However, the strength of the composite of VGCF decreases in the both case of the random alignment and the uniform alignment.
