“…The surface treatment is a key factor, not only as regards the initial adhesive strength, but also and especially in terms of its long-term resistance to external influences, which was confirmed by the research (Baker, Chester, 1992).…”

An adhesive bonding technology is among the basic methods of bonding. However, it is limited by several factors, e.g. a treatment of bonded surface. Structural adhesives are chemicals. It follows that there are significant differences in the mechanical properties among particular types. The aim of the research was to evaluate the mechanical properties of single-component epoxy adhesives used in the transportation industry. The effect of a surface treatment of the steel surface on bond strength was also evaluated. The tested sets were mutually compared using Anova F-test from the point of view of the influence on mechanical properties (the tensile strength of adhesives, the elongation of adhesives, the adhesive bond tensile lap-shear strength, the elongation of the adhesive bond, the impact strength and hardness). The results confirm the assumption about the different behaviour of one-component epoxy. An important part of the experiment was to evaluate the influence of the surface treatment on the bond strength. From the result of experiments it can be concluded that the adhesive SP492 (p = 0.1898) and B5103-3 (p = 0.4263) are resistant to different types of tested treatment of the bonding surface.

“…Work at ARL has concentrated on the development of surface treatment processes suitable for use in a repair environment and for use on both steel and aluminium. The use of appropriate silane coupling agents has been shown to be an effective means of AIRCRAFT ENGINEERING -March 1993 improving bond durability, 19 and recent improvements to this technique have resulted in adhesive bond durability that is comparable to that obtained from anodisation processes.…”

Bonded composite repair technology was pioneered at ARL and has been successfully used to repair a wide range of military and civilian aircraft. The technique has proved to be very cost effective and has been shown to increase the availability of aircraft by significantly reducing the repair time. ARL has undertaken collaborative work with a number of airline operators, the CAA and FAA and with Boeing to demonstrate the advantage of the technology when compared to conventional repair methods. The Defence Science and Technology Organisation (DSTO) has signed a licence agreement with an Australian company. Helitech P/L, to exploit this technology on a world‐wide basis.

“…[14,15] Nanocomposite acrylic adhesives based on colloidal silica (CS) have many advantages such as durable property because of their three-dimensional stability and physical bonding between CS and acrylic adhesive. [16,17] The adhesion of nanocomposite, however, is too low for most usual applications due to its limit on dispersion in organic materials. Therefore, the CS with tailored adhesive properties remains a real technical challenge.…”

Surface-modified colloidal silica (M-CS) nanoparticles were successfully synthesized from colloidal silica (CS) and methyltrimethoxysilane using sol-gel method and characterized by Fourier transform-infrared spectroscopy. Both CS and M-CS were then incorporated into acrylic adhesives. M-CS particles in 2-ethoxyethanol had similar particle size to pure CS based on the characterization by DLS. The morphologies of M-CS particles in acrylic adhesives examined by TEM showed more homogeneous dispersities than that of pure CS which were aggregated and phase separated in acrylic adhesives. In addition, the thermal properties of the nanocomposite acrylic adhesives determined by thermogravimetric analyses and differential scanning calorimetry showed higher glass transition temperature and thermal properties than pure acrylic adhesives. Finally, the 180°peel strength of nanocomposite acrylic adhesives was higher than pure adhesives with improved durabilities.
