| Summary: | This study used screw extrusion-based fused deposition modeling (FDM) with a paraffin-plastic hybrid base binder system to additive manufacture the short fiber-reinforced C/SiC composite. While extensive studies have been conducted on the effects of fiber volume fraction on the additive manufacturing performance of C/SiC composites, research focusing on the influence of fiber length on the properties of sintered ceramics and green bodies remains notably scarce. In view of this, we explored fiber length effects on mechanical properties, feedstock rheology, stacking morphology, and green body density. Results show that suitable length of short fibers contribute to enhanced strength and toughness in composite ceramic, and longer fibers increase feedstock viscosity, cause blurred interlayer boundaries, and reduce green body density. The study exhibits FDM's potential for additive manufacturing of ceramic composites, offering new insights for material preparation. The mechanical properties of short fiber reinforced C/SiC composites can be controlled by selecting the appropriate fiber length. |
