Mechanical Evaluation of the Porous Ceramics Prepared by Filtration with a Framework Structure of the Polycrystalline Fibers

Abstract:

Porous ceramics with a framework structure of the polycrystalline mullite fibers, in which the silica sol were impregnated into the intertwined points, were synthesized by the infiltration method. The sample has a porosity of 90 %, and the compression strength was significantly improved compared with the matrix without any addictives. The elastic behavior was investigated by changing the loading speeds. It is found that the elastic behavior of the porous ceramics was different from the traditional ceramics. The compression set is about 15% and the rebound resilience is 85 % at room temperature. The composite can keep good performance of compression-rebound.
