摘要：
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. Materials with multi-interface structure can improve the flexural strength and fracture toughness, the load-displacement curve shows the load drop is decreased for step type, the composites show a pseudo-plastic fracture characteristics. The flexural strengths of the material A and material B are 206.68MPa and 243.66MPa, the fracture toughness are 8.06MPa·m½ and 9.66MPa·m½, respectively. The flexural strength and fracture toughness of material B are both superior than that of material A. © 2017, Journal of Materials Engineering. All right reserved.
