Analysis on Macro and Micro Mechanical Properties of Wood Composite Panels Based on Finite Element Modeling

Based on the finite element theory, the paper established microscopic unit eell model and macroscopic geometry model for carbon fiber reinforced wood composite panels in the presence of Ansys and resorted to the first-order modal simulation analysis on mechanical properties. The results showed that the physical experiment data and the simulation forecast data are identical with each other, which verifies the validity and reliability of the models and achieves the purpose of the macro performance prediction according to the microstructure of composite and realizes the macro to micro relevance for composite mechanical properties.
