3. Storage modulus values of PB, MDF, and PW panels were far higher than their loss modulus values, and PW panels had the smallest value of loss modulus. 4. For the panels tested, density had a good linear impact on storage modulus and logarithmic decrement had a greater linear effect on loss modulus compared with density.
