PRECURSOR MATERIAL FOR ADDITIVE MANUFACTURING OF LOW-DENSITY, HIGH-POROSITY CERAMIC PARTS AND METHODS OF PRODUCING THE SAME
PROBLEM TO BE SOLVED: To provide a precursor material for additive manufacturing of a low-density, high-porosity ceramic part.SOLUTION: A precursor material comprises a body of refractory fibers and a binder in admixture with the body of refractory fibers. The precursor material further comprises a viscosity control additive in admixture with the binder and the body of refractory fibers to provide an overall mixture with a viscosity between about 0.3 centipoise and about 150,000 centipoise. The binder and an aqueous slurry containing the refractory fibers are obtained, and a slurry with a viscosity that is suitable for extrusion through a nozzle is prepared by adding a viscosity control additive to the slurry and then stirring and mixing them. The overall mixture slurry can be extruded through a nozzle to manufacture the low-density, high porosity ceramic part.SELECTED DRAWING: Figure 3
【課題】低密度、高気孔率のセラミック部分品の付加製造のための前駆体材料の提供。【解決手段】前駆体材料は、耐火繊維の本体、及び耐火繊維の本体との混合物内のバインダーを含む。前駆体材料は、約０．３センチポイズと約１５０、０００センチポイズとの間の粘度を有する全体的な混合物を供給するための、バインダー及び耐火繊維の本体との混合物内の粘度制御添加物をさらに含み、バインダーと、耐火繊維を含む水系スラリを得、粘度制御添加物をスラリに添加し、攪拌混合して、ノズルを通して押し出すことに適した粘度を有するスラリを調製する。全体的な混合物スラリは、ノズルを通して押し出され、低密度、高気孔率のセラミック部分品を製造する。【選択図】図３
