摘要

With growing concerns about sustainability in construction, there is a rising demand for eco-friendly alternatives to conventional materials. The United Arab Emirates (UAE), with its abundant palm trees, presents a unique opportunity to explore the potential of palm wood in building applications. However, despite the prevalence of palm trees, their mechanical properties require improvement so a similar approach to mass timber is applied. Previous trials explored the feasibility of using date palms for small-scale cross-laminated elements, a technique successful with various timber species. Unfortunately, the results for date palm wood were less promising. The use of laminated date palm has shown inconsistent results, leading to its underutilization in the industrial sector. This study focuses on compressing date palm wood to enhance its mechanical properties. Additionally, it investigates the impact of various lamination angles, particularly the common 45-degree angle prevalent in fibre materials sciences but untested for wood. By examining the effects of compression and lamination on palm wood elements this study aims to find optimal parameters that enhance the shear strength of glue lines. This research explores different compression levels (no compression, 0.8 MPa, and 1.67 MPa) across grain angles of 0, 45, and 90 degrees between laminates. Notably, while wood compression does not directly influence bonding strength, findings reveal that the highest bonding strength occurs at a diagonal, 45° angle.
