摘要
Multi-wall carbon nanotubes (MWCNTs) were chemically functionalized by 3-aminpropyltriethoxysilane and used to increase the strength and stiffness of an adhesive for joining carbon/carbon (C/C) composites. The silanized MWCNTs were uniformly dispersed in the adhesive with a good interface adhesion between them. When the content of silanized MWCNTs in the adhesive was 0.2 wt.%, average shear strength of the C/C joint was 10.40 MPa, which was 31% higher than that of neat C/C composites. The adhesive could be cured at room temperature with good heat-resistant property. The MWCNTs reacted with B4C filler to establish strong B-O-C bond with C/C substrate. (C) 2012 Elsevier Ltd.
