Rheological and Dynamic Mechanical Characteristics of Abutilon Natural Straw
0Rheological and Dynamic Mechanical Characteristics of Abutilon Natural Straw and Polylactic Acid Biocomposites: A Detailed Study
Layman Abstract : With growing concerns about fossil fuel use and environmental sustainability, natural fibers are being explored as eco-friendly materials for biocomposites. This study focused on creating biocomposites using polylactic acid (PLA) and abutilon natural straw at different concentrations.
Experiments showed that even small amounts of abutilon straw affected the melting behavior of PLA. Mechanical tests indicated that adding more straw improved material strength and interaction between the components. Microscopic analysis confirmed good straw distribution within the PLA. However, while the straw improved some properties, it also reduced the material’s flow behavior (rheology), especially at higher concentrations.
Future research could examine how temperature affects these biocomposites, helping to optimize their use in sustainable materials.

Original Abstract : In recent years, the requirement for environmentally friendly materials has increased to reduce the consumption of fossil fuels and prevent global environmental concerns. Recently, natural fibers have become attractive materials to engineers, scientists, and researchers as an alternative reinforcement for biocomposites. In this study, polylactic acid/abutilon natural straw biocomposites with various abutilon straw weight fractions were prepared by melt blending. The differential scanning calorimetric (DSC) results showed a significant influence of the abutilon straw on the melting behavior of PLA, even at low abutilon straw contents. The dynamic mechanical analysis demonstrated that the storage modulus, as well as the tan delta of the biocomposites, increased when the abutilon straw content increased, which indicates better interaction between abutilon natural straw and PLA. The incorporation of abutilon straw into biocomposites provided favorable changes in rheology related to the matrix. SEM observation revealed good dispersion of the abutilon straw in PLA. The direct relation between straw content and tan delta also proved the better interaction between abutilon natural straw and PLA. However, the rheological properties decreased with the abutilon straw addition, the most significant effect seen again with the further increasing straw content. This study might be further extended to see the effect of temperature on the rheological properties.
