Abstract

The use of fibre-reinforced polymers (FRPs) in the construction industry is becoming increasingly common. One application of these materials is in the stiffening and strengthening of glue-laminated timber. The research programme discussed in this paper examined the bonding of commercially available FRPs to wood using three commercial epoxy adhesives. The programme involved comparative testing of non-moisture cycled FRP-wood specimens, non-moisture cycled wood-wood bonded, and solid control specimens with moisture cycled FRP-wood specimens all manufactured using wood from the same boards. Findings showed that with specific adhesives, cost-effective thin bondlines have the capacity to resist severe hygrothermal stresses imposed at the FRP-wood interface. It was further noted that the integrity of the bond depended not only on the epoxy adhesive in question but also on the FRP type.
