Rectangular specimens for tension tests, of width of 19 mm or
50 mm and length varying from 10 to 50 mm were cut with a scalpel
from the two tapes. Circular cylindrical specimens were produced
for compression testing by stacking several layers of the
VHB4910 or VHB4905 tape in order to obtain monolithic plates
of thickness of about 5 mm; extreme care was taken to avoid
straining of the tape or trapping of air bubbles in the stacking process.
After stacking it was not possible to separate the layers and
the original interfaces between these were not visible, due to the
good self-adhesion of the polymer
