Abstract

We reported a novel carbon nanotube/pyrocarbon (CNT/PyC) interlayer for joining carbon/carbon composites (C/C). Radially-aligned CNT was in-situ grown on the bonding surface of C/C and followed by the infiltration of PyC between CNT-covered C/C. Mechanical tests indicated that the average shear strength of CNT/PyC-bonded C/C was 19.2 MPa, 104% higher than that of neat PyC-bonded C/C. This great improvement results from the outstanding contributions of CNT involving enhancing interlayer-C/C interfacial interaction, inducing PyC texture to align around nanotubes instead of parallel to the bonding surface and increasing additional fracture process, which change the failure of bonded C/C from bonding-interlayer-failure dominated mode to substrate-failure dominated one.
