Effects of Carbon Fiber Length and Content on Properties of SiC Reticulated Porous Ceramics

Abstract

Abstract: In order to improve the flexural strength of SiC reticulated porous ceramics prepared by the polymer sponge replica technique, the carbon fiber was used to enhance SiC reticulated porous ceramics. The effects of additives and carbon fiber on the rheology and thixotropy of SiC ceramics slurry were studied. Furthermore, the influences of length and content of carbon fiber on the microstructure, porosity, compressive strength and flexural strength of SiC reticulated porous ceramics were also investigated. The results show that the SiC ceramics slurry with 0.1% (mass fraction) dispersant-FS20, 0.1% (mass fraction) thickness agent-CMC and 0.05% (mass fraction) binder-CL exhibits excellent rheological and thixotropic behavior. The viscosity of slurry increases by adding carbon fiber. In addition, with the increase of carbon fiber content and length, the flexural strength of SiC reticulated porous ceramics first increases and then decreases. When the length and content of carbon fiber are 1 mm and 0.75% (mass fraction) respectively, the flexural strength reaches the maximum.

Key words: SiC porous ceramics, carbon fiber, polymer sponge replica technique, flexural strength, additive
