Fabrication and Properties of Cf/Ti3SiC2-SiC Composites Using Ti3SiC2 as Inert Filler
Because Ti3 SiC2 combines the characters of metals and ceramics,such as low density,high Youngs modulus,low hardness,thermal and chemical resistance,high electrical and thermal conductivity,it was expected that the introduction of Ti3SiC2 to fiber reinforced ceramic matrix can make the composite own some unique properties.In this paper,Ti3SiC2 powders used as inert fillers were fabricated by in-situ reaction between Ti and polycarbosilane mixtures.The purity of Ti3SiC2 powders analyzed by XRD was determined by Relative Intensity Ratio method,which is a semiquantitative XRD analysis.The results showed that the purity of Ti3SiC2 powders is about 96%.Cf/Ti3SiC2-SiC composites are obtained by polymer infiltration and pyrolysis process using Ti3SiC2 powders as the inert fillers.The bending strength of Cf/Ti3SiC2-SiC composites was about 160 MPa.
