Adhesion Promoters for Bonding Titanium.

摘要

An investigation was undertaken to determine the feasibility of using adhesion promoters to improve the interfacial bond between titanium and structural adhesives. The dry and wet strengths of titanium/epoxy/titanium lap-shear joints were determined,utilizing gamma-aminopropyltriethoxysilane as the adhesion promoter. The lap-shear joints using gamma-aminopropyltriethoxysilane were found to be approximately 25% stronger dry and more than 50% stronger after water exposure than joints prepared with standard surface treatments.
