| Abstract | The surface of continuous carbon fibers (Cf) was modified with gamma-Al2O3, anatase-TiO2 and yttria stabilized zirconia (YSZ) coatings in sol-gel route, and denoted by Al2O3@Cf, TiO2@Cf and YSZ@Cf, respectively. Following, Cf/Mg composites were prepared using vacuum pressureless infiltration processing. Except for coatings, the others preparation process parameters were same. Independent of the volume fraction of Cf, the strengthening ratio (the ratio of measured tensile strength to theoretically predicted value) of Al2O3@Cf/Mg, TiO2@Cf/Mg and YSZ@Cf/Mg is about 45%, 80% and 90%, respectively. In view of high resolution transmission electron microscope observation, the evolutions of interfacial micro-cracks and interfacial failure mechanisms were analyzed. In YSZ@Cf/Mg, the interfacial micro-crack was more likely to initiate at the soft grain boundaries (GBs) of interfacial layer (IL), and then propagate along GBs within IL, showing jagged-like morphology. The jagged-like micro-cracks would consume more destructive energy, resulting into the excellent performance of YSZ@Cf/Mg. |
