Abstract
A multi-phase matrix C/SiC-W composite was prepared by combining chemical vapor infiltration (CVI) technology with solution impregnation method. The phase composition and microstructure of the composite were identified and characterized by XRD and EDS methods, respectively. Reaction mechanism was discussed primarily. The results show that agglomerate tungsten particles are found to infiltrate the pores among the fiber bundles, also among the filaments. The density and open porosity of the C/SiC-W composite are 4.l g/cm3 and 12%, respectively.
