Abstract

Biomorphic cellular C/SiC-ZrC composite ceramics were fabricated from pine and oak wood precursors. Carbonaceous preforms were first prepared by wood pyrolysis and subsequently infiltrated with polyzirconobutanediol (PZC) and polycarbosilane (PCS) to form the composite ceramics. TGA/DTG and dilatometric analysis were used to study the pyrolysis of the wood precursor. XRD and SEM analyses were applied to characterize the microscopic properties of the resulting biomorphic cellular C/SiC-ZrC composite ceramics. Compared with oak, pine was preferable for preparation of cellular C/SiC-ZrC composite ceramics because of its unique microstructure. The SiC-ZrC phase distribution differed within the composite ceramics. In addition, the compression strengths of wood, charcoal, and cellular C/SiC-ZrC composite ceramics were measured in the axis direction. Results showed the improved compression strength of biomorphic cellular C/SiC-ZrC composite ceramics when the impregnation cycles were repeated. (C) 2015 Elsevier Ltd and Techna Group S.r.l.
