This study assesses the mechanical characteristics of eucalyptus plywood produced in Ghana, particularly focusing on how panel thickness (9–21 mm) and adhesive type (phenol formaldehyde (PF), and melamine urea formaldehyde (MUF) influence the modulus of elasticity (MOE) and modulus of rupture (MOR) of the panels. The panels were tested according to EN 310: 1993. The results indicate that mechanical strength and thickness are inversely correlated, with thinner panels exhibiting superior performance. MOR decreased from 59.85 N/mm² to 39.36 N/mm² for PF-bonded plywood, while longitudinal MOE declined from 7096 N/mm² (9 mm) to 4627 N/mm² (21 mm). Although their values were lower (from 6093 N/mm² to 4155 N/mm²), the MUF-bonded panels demonstrated comparable trends. Significant differences based on orientation were confirmed by ANOVA analysis (p < 0.01), showing that longitudinal samples significantly recorded higher values than transverse ones, particularly in thinner panels. Thicker panels exhibited less anisotropy due to stress homogenization, but PF adhesives provided greater mechanical stability compared to MUF.
