Abstract: Radiations from different electrical devices cause electromagnetic interference which will affect the performance of other electromagnetic devices and cause concerns to public health. The Aluminum plates used for electromagnetic shielding were laminated with thin plywood to prepare a new kind of wood-based composite. Two non-destructive testing (NDT) methods (Metriguard and Cantilever Beam Vibration) and a static bending testing method were used to evaluate the dynamic modulus of elasticity (DMOE) and static modulus of elasticity (MOE) of raw plywood and the composites. The results indicated that there were good relationships between DMOE and MOE of raw plywood and composites except for the composites which its surface was aluminum plates. The cantilever-beam vibration method was found to be the better way to predict MOE.
