Improvement of SiCf/SiC density by slurry infiltration and tape stacking
TL;DR: SiC fiber-reinforced SiC-matrix ceramic composites (SiC f /SiC) were fabricated by vacuum infiltration of a SiC slurry into Tyranno™-SA grade-3 fabrics coated with a 200-nm-thick pyrolytic carbon (PyC) layer followed by hot pressing using a transient eutectic phase.
