碳-碳复合材料是指用碳纤维或其织物作增强剂,以沉积碳或浸渍碳作基体制成的复合材料。碳-碳材料的性能与它的微观结构有密切的关系。揭示材料微观结构组成的常用方法有偏光显微镜、扫描电镜和透射电镜观察。偏光显微镜观察可以了解材料的微观结构概貌,也可以利用偏光下晶体的光学特性(消光现象)看到不同晶相的组成。但是,一般光学显微镜放大倍数较小(1500倍以下),有些结构
Carbon-carbon composite refers to the use of carbon fiber or fabric as a reinforcing agent to deposit carbon or impregnated carbon as a matrix made of composite materials. The performance of a carbon-carbon material is closely related to its microstructure. Common methods to reveal the microstructure of materials include polarized light microscopy, scanning electron microscopy and transmission electron microscopy. Polarizing microscopy can be used to understand the microstructure of the material. The composition of the different crystalline phases can also be seen using the optical properties (extinction) of the crystals under polarized light. However, the general optical microscope magnification less (1500 times less), some structures
