Description
Summary:•Polymer infiltration and pyrolysis (PIP) process are employed to fabricate ceramic composite.•SEM micrographs and X-ray CT scan analysis indicated cracks and voids in the composite.•Mechanical properties of preceramic composite are affected by the existence of porosity and cracks after sintering.•Multiple infiltrations with SPR 212 results in a void and crack reduction and enhance mechanical properties. Preceramic polymers, which are converted into ceramics upon heat treatment, offer an advantage of combining the shaping and synthesis of ceramics parts. In this work, the Polymer Infiltration and Pyrolysis (PIP) process is employed to fabricate ceramic composite prototypes using preceramic polymers with carbon/glass fabrics, followed by experimental investigations of the mechanical properties of the ceramic composite samples (e.g. hardness and compression strength). X-ray micro computed tomography and SEM analysis were conducted to examine the effectiveness of the PIP.
