Abstract

Abstract: 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 2.83 ± 0.03 g/cm 3, 249 ± 17.0 MPa and 3.48 ± 0.24 MPa m 1/2, respectively. It demonstrates the capability of making near net-shape Cf /SiC composite parts with complex structures.
