英文摘要	Boron nitride nanowires (BNNWs) were first grown in situ into fiber preforms, and then Cf/SiC composites reinforced with the BNNWs were fabricated by means of chemical vapor infiltration (CVI) matrix densification. It was found that thanks to the incorporation of the BNNWs, the matrix of the C-f/SiC composites at micron scale is toughened notably, as evidenced by the results of indentation tests. Synergetic strengthening and toughening mechanisms including debonding, fracture, pullouts as well as crack branching and deflection attributed to BNNW-based micro rods are observed. However, no significant increases in flexural strength and fracture toughness are obtained for the composites, possibly owing to the lower density of composites and strong interface bonding between the BNNWs and the matrix.
