11. Conclusion
The hybrid composites from wood fiber, talc and a bioplastic
PHBV using the extrusion–injection molding technique were successfully
fabricated. The composition at 20 wt.% of wood fiber
and talc in PHBV gave a leap of 200% improvement in the Young’s
and flexural modulus. The dynamic-mechanical analysis is in confluence
with the tensile and flexural analysis as well as explains
the talc–PHBV and wood fiber–PHBV interfacial interactions. The
high surface energy of talc particulates due to its high acidic character
provides an opportunity of better talc–PHBV interfacial interactions
than wood fiber–PHBV interface. The DSC analysis does not
depict any additional crystallization of PHBV due to the addition of
talc in it. The impact strength of the PHBV does reduce with addition
of talc and wood fiber. The Morphological analysis of the hybrid
composite using SEM reveals the better interfacial
interaction and dispersion of talc with PHBV than wood fiber.
The HDT and CLTE improved in advantageously.
