ABSTRACT
This paper presents experimental results of the mechanical behaviour of LVL (Laminated Veneer Lumber) made of poplar reinforced with fiber reinforced polymer (FRP) subjected to shear and compressive stresses. Through mechanical properties such as strength, stiffness, maximum displacement and non-destructive measurements of elastic moduli in compression and shear, the influence of different variables was analysed: 1) Type of FRP (carbon or basalt); 2) Fiber direction; 3) Quality of veneer. The influence of veneer quality under compressive stresses and the difference between carbon and basalt under shear stresses have been verified. In addition, for the unidirectional carbon reinforcement, improvements up to 21% in compressive and shear stiffness and elastic modulus was achieved, respectively.
