| Abstract Scope |
Waste coal and phenolic resin thermoset formulations were developed for additive manufacturing of continuous, crack-free, amorphous carbon structures. The resulting carbonized 3D printed structures have high carbon yields and can tolerate high temperatures and rapid temperature fluctuations. The coal-filled thermoset resin is extruded in layers at room temperature using the same printing technologies that are commercially available for concrete and clay 3D printing. Curing is thermally initiated post-printing followed by carbonization of the coal waste-phenolic resin composite at 1000°C. The impact of resin formulation, mixing, thick paste rheology, cure parameters, and carbonization on the print quality, carbon yield, shrinkage, and strength of the resulting cured composite and carbonized parts will be discussed. |
