Numerous benefits are associated with the reinforcement of low grade wood by pultruded glass fibre reinforced polymers (FRP). It is imperative in composite design that a successful bond is established between the dissimilar materials. This paper describes a program of ambient testing carried out to evaluate the performance of a range of adhesive types when bonding softwood that contained large proportions of juvenile wood, with viable FRP materials. The adhesive selection and FRP type proved more significant in achieving a good quality bond than variations associated with the wood samples. Two epoxy adhesives studied exhibited most consistency in establishing good quality bonds. Generally, FRP-wood bonded specimens failed at comparable shear strengths to solid specimens but at lower shear strengths than those achieved by wood-wood bonded specimens from the same plank. The use of an adhesion promoter appeared to have no improvement on the bond during ambient testing.
