Poor flowability of printable powders and long preparation cycles are the main challenges in selective laser sintering (SLS) chopped carbon fiber reinforced silicon carbide composites (SiC composites) with complex structures. In this study, we develop an efficient novel processing route fabrication lightweight SiC via SLS phenolic resin (PR) C_f addition α-SiC particles combined one-step reactive melt infiltration (RMI). The effects on microstructural evolution C_f/SiC/PR printed bodies, C_f/SiC/C green derived were investigated. results indicate that added play important role enhancing raw powders, reducing porosity, increasing reliability contributing to improving microstructure homogeneity mechanical properties composites. maximum density, flexural strength, fracture toughness 2.749±0.006 g×cm⁻³, 266±5 MPa, 3.30±0.06 MPa·m^1/2, respectively. coefficient thermal expansion (CTE) is approximately 4.29×10⁻⁶ K⁻¹ from room temperature (RT) 900 °C, conductivity range 80.15-92.48 W·m⁻¹·K⁻¹ at RT. high-temperature strength increase 287±18 MPa up 1200 °C. This study provides a as well feasible tactic for high-quality lightweight, high structures by RMI.
