碳/碳复台材料是一种新型的高温材料,在发展航空和航天等尖端技术方面它具有重要的意义。采用不同复合工艺制得的碳/碳复合材料的机械性能和烧蚀性能与复合工艺过程所形成的聚合物碳多相微观结构和缺陷特征有密切的关系。我们曾总结了用电子显微镜研究浸渍法所得3DCC复合材料的多相微观结构和缺陷特征。对化学气相沉积法(CVD)碳毡/碳复合材料的形态结构的研究,过去人们多数是采用光学显微镜或扫描电子显微镜(SEM),但对CVD碳毡/
Carbon / carbon composites are a new class of high temperature materials and are of great importance in developing cutting-edge technologies such as aerospace and aerospace. The mechanical and ablative properties of carbon / carbon composites prepared by different composite processes are closely related to the multiphase microstructure and defect characteristics of the polymer formed by the composite process. We have summarized the heterogeneous microstructure and defect characterization of 3DCC composites obtained by impregnation using an electron microscope. The chemical vapor deposition (CVD) carbon fiber / carbon composites morphological structure of the study, the past, most people use optical microscopy or scanning electron microscopy (SEM), but the CVD carbon felt /
