چکیده انگلیسی
A novel method has been developed to fabricate carbon fiber reinforced SiC (Cf/SiC) composites by combining 3D printing and liquid silicon infiltration process. Green parts are firstly fabricated through 3D printing from a starting phenolic resin coated carbon fiber composite powder; then the green parts are subjected to vacuum resin infiltration and pyrolysis successively to generate carbon fiber/carbon (Cf/C) preforms; finally, the Cf/C preforms are infiltrated with liquid silicon to obtain Cf/SiC composites. The 3D printing processing parameters show significant effects on the physical properties of the green parts and also the resultant Cf/C preforms, consequently greatly affecting the microstructures and mechanical performances of the final Cf/SiC composites. The overall linear shrinkage of the Cf/SiC composites is less than 3%, and the maximum density, flexural strength and fracture toughness are 2.83â¯Â±â¯0.03â¯g/cm3, 249â¯Â±â¯17.0â¯MPa and 3.48â¯Â±â¯0.24â¯MPa m1/2, respectively. It demonstrates the capability of making near net-shape Cf/SiC composite parts with complex structures.
