| description | In order to improve the density and mechanical property of ceramics fabricated by selective laser sintering (SLS) process, a new method that combined SLS with precursor impregnation and pyrolysis (PIP) process was presented to fabricated silicon carbide particulate/silicon carbide matrix (SiC/SiC) ceramic composites Starting with SiC powders of 17~70 μm sizes, the preform was produced by printing epoxy binder To gain the dense composites, the SiC preforms were infiltrated with polycarbosilane liquid and pyrolyzed at 1200℃ under nitrogen atmosphere for 8 repeated cycles The porosity of the specimen greatly decreased and the density reached to 245 g/cm3 after PIP process Analysis of results and discussions of optimum printing parameters, dimension accuracy, microstructure and bending strength for SiC/SiC composites are also presented The mechanical property of the SiC/SiC composite fabricated by SLS/PIP process has been improved and its bending strength attained 13828 MPa In addition, the netshape silicon carbide components with complex surface and inner structure were fabricated |
