1/4/2012& 0183;& 32;The activation energy at the damping peak for composites from extracted wood flour was higher than one for un-extracted wood flour in samples without MAPP . The higher activation energy suggests a better dispersion of filler in the matrix or possibly better interaction between the filler and the matrix so that more energy is required to move the molecules 48 .
