The density of hybrid composite at 20 wt.% talc and wood fiber
each, as measured was 1.39 ± 0.03 gm/cm3, and Table 2 lists the
density of PHBV and its composites with wood fiber and talc alone.
The density was determined by using the buoyancy method i.e.,weighing the specimens, when fully immersed in water. This was
compared to the determination form the X-ray densometer. The results
were comparable with both the methods
