This study produced cross-laminated timber panels at a range of four lamina thickness (5/8, 1, 1 1/8, and 1 1/4 inch) and three bonding pressures (50, 125, 200 psi), producing a total of 12 panels for mechanical testing. The goal of this study is to observe how the thickness and pressure trends affect the mechanical properties of CLT. Tests include flatwise bending, flatwise shear, internal-bond, and delamination. Results showed that bending MOE decreases as the panel thickness increases while bonding pressure had no significance. Bending MOR was less significant for the thickness and more significant for pressure compared to the MOE. Shear tests showed strong inverse relationship between MOR and thickness while increasing pressure strongly increased MOR. Internal-bond testing showed no clear relationship between thickness or pressure. Delamination decreased as a result of higher pressures while thickness had no significant affect.
