4.1 INTRODUCTION
Rods, dowels, and plates are bonded into timber with high strength adhesives for timber connections and are widely used for repair of timber structures [1-4]. Rods or plates made from pultruded fiber reinforced plastic (FRP) or metal are bonded into timber using structural adhesives. The adhesives are back-injected into oversize holes
or slots and the rods or plates are pushed into the adhesives forming a void-free interface and the adhesive is allowed to cure. The bond integrity influences the ultimate capacity of the bonded structure as well as serviceability and depends on a number of factors including the type of adhesive and adherend, cure cycle, bondline thickness, and the environment.
