ABSTRACT:
The thermal, rheological and morphological properties of composite
biomaterials made with mixture of high density polyethylene and typha rod
powder (RD) were evaluated. The dynamic mechanical behavior of the samples was
studied with 25%, 35% and 45% typha stem powder concentrations. The
viscoelastic properties are mainly related to the nature of the polymer and the
typha stem powder. Storage (G') and loss (G") moduli increased
significantly, depending on the amount of powder in the molten mixture. After a
viscosity increase was noticed in low frequency, it decreased in high
frequencies, which demonstrates the pseudo-plasticity effect. Morphological and
thermal characterization results have shown the dispersion state of the powder
and its ability to modify the kinetics crystallization of biocomposites.
