One opportunity for the value-added utilisation of domestic poplar hybrids is manufacturing LVL products. The mechanical properties of poplar LVL are somewhat inferior to those of traditional Spruce/Pine LVL products. These characteristics may be improved by reinforcing the product using hardwood veneer layers. In this study, the mechanical properties of poplar LVL were improved using beech, turkey oak and tree-of-heaven as reinforcement layers. The mechanical properties of the experimental LVL were determined using vibration testing and destructive ramp testing. The MOE was also estimated using a deterministic model based on the elastic properties and densification of the veneer layers. In this article, the non-destructively measured and model-predicted elastic properties are described. The reinforcement layers improved the MOE significantly. Beech reinforcement performed as anticipated, while turkey oak and tree-of-heaven veneers increased the MOE more drastically than expected. This indicates that these veneers are especially suitable for this purpose. The theoretical model predicted the MOE of the control and beech-reinforced specimen reasonably well, but provided a conservative estimate for the effect of turkey oak and tree-of-heaven.
