Abstract
The possibility of fabricating SiC ceramics using special wood-based materials has been shown in previous research. To form accurate SiC bodies from wood-based green templates, special shaping techniques are necessary to fulfill the requirements on the finished ceramic products. Due to the fact that wood-based green templates undergo shrinkage during carbonization, no suitable forming processes for the wood-based green templates have been presented so far. In this publication different raw materials and 3D shaping production processes and their influence on green body properties are described. It was possible to produce green bodies with a MOR higher than 15 N/mm² and a density in the range above 0.82 g/cm³. It is shown that reduction of resin content decreases the strength significantly and a reduction to 30 mass % resin content reduces the MOR of flat pressed panels to the defined limit. The extruded samples showed a significantly lower strength (mean 18.1 N/mm², standard deviation 8.6 N/mm²). Injection molding was not applied successfully. The findings show that shape pressing and extrusion were applied successfully, but the green body properties differed significantly from the results achieved by flat pressing.
