Title of Paper:Effects of electrophoretically deposited graphene oxide on the surface of TA2 on the bonding strength of Ti/PEEK

Journal:ICCM Int. Conf. Compos. Mater.

Abstract:In order to improve the adhesive strength of Ti/PEEK interfacial adhesive in Ti/PEEK/Cf fiber metal super-hybrid laminates, the graphene oxide (GO) was deposited on the titanium plate surface by electrophoretic deposition method. Firstly, the anodic electrophoretic deposition method was used in the water dispersion solution of GO, then the morphology and properties of titanium plate surface before and after GO deposited were characterized by SEM, contact angle. And the properties change of GO after heated under 390°C were characterized by Raman spectrum and FTIR spectrum. According to the result of Raman spectrum, GO dispersed on the titanium plate surface with no apparent reunion. After 390°C heated 1h, the oxygen functional group of GO lost apparently. The observation of surface topography by scanning electron microscope showed that the GO distribution of titanium plate surface deposition was relatively uniformly. While the GO surface has a large number of folds, which is beneficial to increase the contact area of resin peek. According to the results of single lap tensile shear test, the adhesion strength of Ti/PEEK interface after deposition GO was 32.54MPa, compared to the non-deposited 27.04MPa increased by 20.3%. It indicated that the Ti/PEEK interfacial adhesive strength can be obviously improved after the deposition of GO. © 2017 International Committee on Composite Materials. All rights reserved.
