Methods and apparatuses for joining titanium and titanium alloy structures to epoxy-containing compounds

Abstract:

Adhesion of a metal surfaces (e.g. titanium and titanium alloys) to an epoxy resin is improved by creating a sol-gel layer at the metal/epoxy resin surface, with the sol-gel comprising a mixture of organometallic compounds to react with or bond to both the metal surfaces and an interfacing epoxy resin.
