By sintering the mixture of Cf with high thermal conductivity and Cu powders by SPS process at 1073-1173K in temperature, the preform for low-pressure infiltration of molten aluminum was obtained. Cu particles connected with Cf in preform, and many fine Cu droplets were deposited at Cf surface. Preform has good compressive strength with over 1 MPa, which is enough strength for the low-pressure infiltration. Then, molten pure aluminum was infiltrated to the preform by low-pressure infiltration with 0.2-0.8MPa. As increasing the applied pressure, the density of composites and the dispersity of Cf in composites increased.
