High-performance nanoadhesive bonding of titanium for aerospace and space applications

Effect of Surface Texture on the Adhesion Performance of Laser Treated Ti6Al4V Alloy

“…While fasteners can be adequate to most of the material couples, welding technologies are limited to join titanium alloys with other metallic alloys, and some polymeric materials. Another option that is widely used in aeronautics and aerospace applications, which also receives an increasing attention for joining titanium alloys, is the use of adhesives [6][7][8]. Adhesive bonding provides flexibility in joint design and is cost effective due to the reduced machining time and scrap material.…”

Atmospheric pressure plasma surface modification of titanium for high temperature adhesive bonding

“…For improving the performance of adhesive bonding of titanium for aerospace and space climatic conditions, it is necessary to modify the surface of titanium [5]. The main area of environmental attack on a polymer metal bond is at or close to the adhesive or primer/oxide interface resulting in adhesive failure.…”

Nanoreinforced Adhesives

“…This increase is related to the enhancing of the plastic deformation of the epoxy matrix due to the appearance of different toughness mechanisms, such as crack deflection and crack twisting around the nanoparticles. On the other hand, Bhowmik et al (2009) probed that the exposure under high-energy radiation of a nanosilica reinforced epoxy resin causes an increase of its crosslinking density, essentially affecting the overall behaviour and mechanical properties of the nanoreinforced polymer. In fact, they report an increase of more than 100% of the lap shear strength of the titanium joints when the adhesive was reinforced with nano-silicate particles and exposed to high energy radiation regard to the adhesive strength of non-modified adhesive.…”
