Composite materials are made of vapor-grown carbon fibers (VGCF) with aluminum based matrices. Two aluminum based matrices such as pure aluminum matrix and matrix added Al-12 Si to pure aluminum are chosen for the composite materials. The thermal conductivities of the composite materials were measured by the method of laser 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-12 Si 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 of VGCF is higher than that with the random alignment of the VGCF. However, the tensile strength of the composite of VGCF decreases in both case of the random alignment and the uniform alignment.
