Based　on　stereolithgraphy　(SL)　and　gelcasting　technologies,　the　integral　fabrication　technique　of　ceramic　mold　for　hollow　turbine　blade　was　put　forward.　The　casting　process　of　blade　requires　that　the　ceramic　mold　should　have　a　porous　microstructure　for　gas　permeability　and　deformability　to　prevent　hot　tearing　of　the　alloy.　In　order　to　fabricate　a　mold　with　controlled　porosity,　chopped　carbon　fibers　were　introduced　as　pore-forming　agent　in　this　study.　The　result　found　that　the　drying　shrinkage　of　green　samples　was　reduced　to　0.12%　after　carbon　fibers　(CFs)　were　added.　Unlike　traditional　pore-forming　agents,　the　mid-temperature　strength　(400　°C)　was　improved　rather　than　decreased　from　1.75　to　3.42　MPa.　The　porosity　of　the　final　mold　increased　from　26%　to　39.7%,　while　hollow　rod　arrays　(microtubes)　could　be　observed　by　scanning　electron　microscopy　(SEM).　At　last,　a　bulk　ceramic　mold　for　a　gas　turbine　blade　was　fabricated　successfully,　which　was　validated　by　X-ray　scan.　Copyright　©　2015　MS&T15®.
