摘要
Amine-functionalized carbon nanofibers (A-CNFs) were deposited on the surface of individual sized carbon fibers using electrophoretic deposition (EPD), and the average interfacial shear strength (IFSS) was determined using the single fiber fragmentation test in conjunction with Weibull analysis. The IFSS decreased by 25% for fibers acting as the negative electrode in water without CNFs, and the impact of agglomerates on IFSS estimation is discussed. Further, a 187% IFSS increase was achieved for fibers undergoing a two-stage A-CNF EPD approach. (C) 2013 Elsevier Ltd. All rights reserved.
