Based on the traditional laminated structure composite materials and titanium alloy bonding

the composite/titanium alloy bondline internal quality and bonding strength under different factors were studied from the aspects of titanium alloy surface treatment methods

adhesive layer thickness and other aspects. The results show that: the bondline internal quality of composite/titanium alloy adhesive test pieces are all intact while the bonding strength between the laminated structure composite and the titanium alloy is higher than that of the woven structure composite under different processes; the pickling and grit blasting on the surface of the titanium alloy is more conducive to the composite structure/titanium alloy than the polishing treatment

and the bonding strength can be significantly improved by using surface pretreatment agent to treat the bonding surface of titanium alloy; the thickness of the adhesive layer has a great influence on the bonding strength of the composite structure/titanium alloy.
