Linear Relationship between Dynamic Youngs Modulus and MOR of the Poplar LVL Reinforced with Monolayer Fiberglass Mesh

摘要：

In this paper, the poplar LVL was reinforced with monolayer fiberglass mesh. The reinforcing effect of monolayer fiberglass mesh on improving the static bending strength (or modulus of rupture, MOR) was studied. And three different nondestructive testing (NDT) methods, such as the longitudinal transmission method, longitudinal vibration method and flexural vibration method (out-plane and in-plane), were used to test the dynamic Youngs modulus of the reinforced poplar LVL. The linear relationships were investigated between the four dynamic Youngs moduli and the MOR of the reinforced poplar LVL. It can be concluded that the three NDT methods are useful for predicting the MOR of reinforced LVL, but the flexural and longitudinal vibration methods had better accuracy to estimate the MOR.
