Abstract

The research focuses on the assessment of the performances of glued laminated wood joint for outdoor window profiles applications, proposing a methodology to appreciate the quality and strength of both bond lines and upright-crossbar tenon-mortise joints. The rationale of the research relies on the potential damages (i.e. breaking of the frame) that can be caused by poor gluing processes and/or typology of adhesives. Despite of this, there is a lack of specific standards related to gluing assessment for outdoor wood frames, which can be able to take into account all the factors affecting the gluing quality. The proposed methodology has been tested on laminated window profiles manufactured from red oak (Quercus Rubra). A commercially available thermoplastic resin-based adhesive has been used for experiments. Shear strength of the laminated samples and compression strength of upright-crossbar corner joints have been measured. The experimental results show that the bond line strength of red oak is decreased by the conditioning processes. A reasonable explanation is that the conditioning process increases the swelling of the samples, and the high differential swelling between axial and transverse directions of red oak can contribute to lower bond line strength. Moreover, the test results show that the tenon-mortise joints strength exceeds the admissible load to preserve the functionality of the frame.
