The microstructure and mechanical properties of two kinds of dual-matrix C/C composites were studied by polarized light microscopy(PLM),scanning electron microscopy(SEM)and mechanical properties tests techniques respectively.PLM results indicate that the matrix carbon exhibits the smooth laminar structure of the pyrocarbon,the isotropic,mosaics and flow domains of the pitch carbon.The TEM results show the normal pitch carbon is the grape structure;the mesophase pitch carbon is the lamellar banded structure....
