英文摘要	Pyrocarbon (PyC) matrices were prepared in two kinds of quartz fiber preforms by chemical vapor infiltration (CVI), and then the fibers were leached by HF. Effects of CNTs on the microstructures and mechanical properties of the quartz fiber reinforced carbon composites and PyC matrices, as well as the interface behaviors of the fiber reinforced composites, were discussed. Randomly oriented CNTs reinforced PyC micro-composites account for the pseudo ISO structure and contribute to the mechanical properties of the PyC matrix. Relative strength between reinforcement and matrix and interface bonding significantly affect the mechanical behaviors of the quartz fiber reinforced pyrocarbon composites: Quartz fiber with low strength and strong interface bonding result in limited strengthening effect on flexural strength of the fiber reinforced composite; low strength unidirectional quartz fiber and weak interface bonding in a much stronger matrix result in limited strengthening effect on tensile strength of the composite. © 2020 Elsevier Ltd
