| Abstract: | Carbon fiber reinforced ultra high temperature ceramic composites were prepared by precursor infiltration pyrolysis.The characteristics of carbon fiber,matrix and fiber-matrix interface of the composites were obtained by microstructures analysis.The correlations of processing-microstructure-mechanical properties were illustrated by the analysis of the precursor properties,the preparation,mechanical properties and microstructure.Results show that less dipping cycles and pyrolysis time can reduce the damage o... |
