Dominant factor analysis of dynamic Young modulus of poplar LVL.

In this study, grey theory was used to analyze the influence of different production processes on the dynamic Young modulus, such as pressure, adhesive spread, press duration and press temperature. So this study designed flexural vibration test, measured the dynamic Young modulus of poplar LVL under different experimental conditions, and analyzed the experimental data with grey relation. The results showed that it is feasible to use grey theory to analyze the impact of production technology of poplar LVL on dynamic Young modulus.
