Mechanical properties of C–SiC composite materials

After laminating 20 plies of the fabric phenol resin (KRD-HM2 Kolon Chem South Korea) was made to impregnate the laminate using the vacuum-assisted resin transfer molding process The impregnated laminate was cured at 120℃ and subjected to a carbonizing process at 1900℃ in a nitrogen atmosphere to produce a porous C/C preform All the composites used in this study
