Fig. 1 illustrates the variation of TS as a function
of irradiation dose for the unloaded as well as
loaded blends. The TS values for unirradiated and
unloaded blend as well as corresponding loaded
ones are also given in the same figure for sake of
comparison. It can be seen that these unirradiated
blend compositions have attained comparatively
low TS values that extend over a limited range.
On the other hand, the tensile values attained for
unloaded as well as loaded blends increased with
irradiation dose reaching its maximum value at
150 kGy and then they decreased over any further
increase in dose. Moreover, it may be observed that
unloaded blend has attained the lowest TS value
over the whole range of irradiation and that the values
attained by loaded composites increase with the
degree of loading with the filler.
