Mechanical, and Rheological Properties of Recycled HDPE and Palmyra Palm (Rônier) Leaf Fibers Based Biocomposites

Recycled HDPE (rHDPE) from the plastic waste was used with different weight percentage of Palmyra palm (Rônier) leaf fiber (RLFs) (5%, 10%, 20% and 40%) to prepare ecofriendly friendly polymer biocomposites. FTIR spectrometer, tensile test, dynamic rheological test, hardness test and density measurement were used to determine the structural, mechanical and physical properties of the biocomposites. The FTIR analysis show chemical interaction between rHDPE and RLFs leading good adhesion. This result was confirmed by the decrease of crossover frenquency of storage modulus G? and loss modulus G? and the increase of hardness and density by increasing the RLFs content. G? and G? were found to increase with increasing both the filler content and the angular frequency. At low frequencies the loss factor tan? increases with the frequency and decreases with the bio-filler content. And at high frequencies, it decreases with both the angular frequency and the amount of RLFs in the composites. The complex viscosity ?* was found increasing with increasing the RLFs amount in biocomposites and decreasing with increasing angular frequency.
