“…It was found that UV rays caused photo-degradation of the top surface of the FRP strips. This led to the decolorisation of the FRP strips and eventually a reduction in shear and tensile strengths of the FRP material [20]. Temperature also plays an important role when it comes to the long-term performance of the timber-FRP interface.…”

“…Any change in moisture content can cause a drastic effect on the dimension and strength of timber products. Moreover, researchers claim that the adhesive strength also reduces under continuous wet and dry cycles throughout the design life of the structure [8,18,20,21,24].…”

Timber as a structural material has been in use since the medieval period. Even today, there are many residential houses being built with timber frame in Australia. Wooden wharfs and bridges are common examples of timber structures in coastal regions of Australia. Humidity in such coastal regions is often high causing an increase in moisture level in the timber structures. Besides, over-loading, rot and decay, termites and borers, etc. cause damage to timber and presence of moisture either aggravates this or favours such causes. Hence, there has been an increased demand for repair and rehabilitation of heritage and important timber structures. Strengthening wooden structures with fibre reinforced polymers (FRPs) is becoming popular in the construction industry. The objective of this paper is to demonstrate the effect of moisture on the durability of the timber-FRP interface. After reviewing previous studies in the durability of the timber-FRP composite, it has been found that prolonged moisture exposure leads to premature debonding in the timber-FRP interface. A graphical representation of the effect of moisture on bond failure has been established through this research work after investigating the previous work of scholars. This paper also highlights the significance of applying adhesion promoter in enhancing the performance of timber-FRP interface.

“…The goal is accomplished using stresses from one member to another by transmission which is distributed consistently and can be achieved with mechanical fasteners. The structural strength is restricted to area of members in contact with fasteners during mechanical fastening [4,[32][33][34][35][36][37][38][39][40][41][42][43][44][45][46][47][48][49][50][51]. Obtaining stronger adhesive bonds than adherents is not at all a strange.…”

The article critically reviews about adhesives and their various adhesion phenomenons along with their categorization and functions. Benefit and drawbacks of adhesives joining was explained. Requirements for excellent bonding which includes, appropriate selection of adhesive, superior design for joining, surface cleansing, wetting were defined. The review clearly indicates the various theories involved in adhesion are namely mechanical interlocking, electrostatic, diffusion, wetting, chemical bonding, and weak boundary layer. Bond failure modes and their mechanism were elaborated briefly.
