| 摘 要： | 采用化学气相渗透(CVI)结合溶液浸渍法制备C/SiC-(W-C)多元基复合材料,利用XRD,EDS和SEM技术对材料的物相组成及微观结构进行表征,并对W-C基体的形成机理进行了初步探讨.结果表明:W-C不仅分散在纤维束间,还分散在纤维束内.C/SiC-(W-C)复合材料的密度为3.4g/cm3,开气孔率为11%.

| Abstract: | A multi-phase matrix C/SiC-(W-C) composite was prepared by combined chemical vapor infiltration(CVI) technology with solution impregnation.The phase composition and microstructure of the composite were identified and characterized by XRD,EDS and SEM methods.Reaction mechanism was discussed primarily.The W-C was found to infiltrate the pores among fiber bundles,also among the filaments.The density and open porosity of the prepared C/SiC-(W-C) composite were 3.4g/cm~3 and 11%,respectively. |
