Abstract

Dynamic mechanical properties (DMP) from 100 to 400 K have been determined for black cherry, carbonized at temperatures from 593 to 1173 K in an inert atmosphere. The elastic modulus of a specimen carbonized at 593 K shows a marked decrease with heat treatment, but this trend appears to be reversed as the carbonization temperature is increased. Internal friction data suggest that there are relatively complex relaxations for all specimens. Scanning electron micrographs for carbonized black cherry, birch, ash, and white oak are presented. The amount of cellular integrity that remains after carbonization in an inert atmosphere is displayed. This form of specimen preparation appears to be a very useful method for investigating certain ultrastructural features of wood.
