Fabrication of Carbon Nano-Fiber / Aluminum Composites by Low-Pressure Infiltration Method

摘要

In this study, the fabrication of carbon containing aluminum composites was attempted by using low-pressure infiltration method. At first, porous preform containing vapor grown nano-fiber (VGCF) and pure aluminum powder was fabricated by spark plasma sintering (SPS) method. Porosity in preform was controlled by changing the applied pressure during plasma sintering. Consequently, the porous preform with 40-50vol% in porosity was obtained, which has enough compression strength for low-pressure infiltration (
