| Abstract: | With the help of Polarization Microscope,the textures and microstructure of pyrolytic carbon matrix produced in limited temperature forced-flow chemical vapor infiltration (LTCVI) were investigated.The mechanical behavior of carbon carbon (C/C) composites produced by LTCVI are also discussed.Furthermore,the relationship between microstructure and mechanical properties was investigated formations of smooth laminar,rough laminar and isotropic were explained;the formations of smooth laminar,rough laminar and isotropic in LTCVI were explained. |
