The Dominant Factor Analysis of Dynamic Shear Modulus of Poplar LVL Based on Grey Theory

摘要：

Wood is one kind of natural renewable eco-material.Laminated veneer lumber (LVL) is an engineered wood product made from veneers glued together with parallelly oriented grains under heat and pressure.This paper designed Poplar LVL production experiments under different process conditions,and measured the mechanical properties of poplar LVL specimens under different experimental conditions.In this study,grey theory was used to analyze the influences of different production processes on the mechanical properties,such as press duration,press temperature,pressure and adhesive spread.The results showed that,it is feasible that grey theory is used to analyze the influence level of production technology of poplar LVL on the mechanical properties.So this paper offered a new method to analyze and design the production technology of LVL.
