In this paper, unidirectional SiC fiber (SiCf) reinforced geopolymer composites (SiCf/geopolymer) were prepared and effects of fiber contents on the microstructure and mechanical properties of the composites in different directions were investigated. The XRD results showed that addition of SiCf retarded geopolymerization process of geopolymer matrix by weakening the typical amorphous hump. SiCf in...
In this paper, short SiC fiber (SiCsf) reinforced geopolymer composites (SiCsf/geopolymer) were prepared and effects of fiber contents and lengths on the microstructure and mechanical properties of the composites were investigated. In-situ crack growth was carried out to study the fracture behavior and toughening mechanism of the composites. The results showed that SiCsf/geopolymer composite developed...
