Abstract
For applications in civil infrastructure rehabilitation and new construction, wood is being reinforced with externally bonded laminates and fabrics of fiber-reinforced polymer (FRP) composites. The potential benefits of external reinforcement with bonded FRP composites have been demonstrated through several studies, and the field implementation of this technology has been successfully proven in numerous projects. However, there is a concern with the reliable performance of the interface bond, since an inadequate bond strength and integrity can render the reinforcement ineffective and lead to premature failure of the structure. The service performance of wood-FRP bonded interfaces under static, environmental and cyclic loads is presented. The durability and shear strength of wood-FRP is evaluated by modified ASTM tests. An innovative contoured double cantilever beam (CDCB) and tapered end-notched flexure (TENF) specimen is used to evaluate the mode-I and mode II fracture and fatigue of wood-FRP bonded interfaces. Based on this study, recommendations and guidelines are given for characterization and evaluation of wood-FRP bonded interfaces. The proposed approach can further be extended to characterization of other bonded interfaces for dissimilar materials.
