Mechanical Properties of Laminated Veneer Lumber (LVL) Fabricated from Three Malaysian Hardwood Species
Abstract
Theapplication of laminated veneer lumber (LVL) has long been limited to non-structural elements in Malaysia.LVL is commonly fabricated with veneer from low to medium density (290 to 630 kg/m3)softwood or temperate hardwood. The data on the properties of LVL made from medium to high density (567 to 687 kg/m3)tropical hardwood species is very limited. Therefore, this study investigated the mechanical properties of LVL fabricated from Malaysian hardwood species namely Kasai (Pometiaspp.), Mengkulang (Heritieraspp.) and Kedondong (Canariumspp.). Different variables were studied: i) wood species; ii) loading direction (flatwise or edgewise), iii) grain direction (parallel and perpendicular), iv) treatment condition. The bending and compression test was carried out in accordance with EN 408:2012, while the block shear test was conducted based on EN14374:2004 and EN 314-1:2004.The results show that the grain direction has the most significant effect (P≤ 0.01)on bending, compressive and bonding properties of the samples tested. The treatment conditions for block shear test also displayed significant effect on its shear strength. The samples loaded parallelly displayed 320-450% higher bending valuesthan the samples loaded perpendicularly. The compressive strength and compressive modulus were 323-365% and 523-2530% higher respectively when loaded parallelly.LVL performed the best mechanically when loaded parallelly and when subjected to Treatment A which was the least extreme treatment condition.
