Comparison of mechanical stability and morphology study between tree fibres and shrub fibres reinforced epoxy bio-composites

The material properties of bio-composites reinforced with natural fibers from shrubs
(Tinospora cordifolia and Ipomoea staphylina) and trees (Morinda citrifolia and
Tamarindus indica) are investigated in this study. Evaluation of these bio-composites’
mechanical characteristics and microscopic structure was the main goal, with a
comparison of the efficacy of shrub and tree fibers for use in future automobile structural
parts, airplane interiors, and consumer goods in mind. Because of their unequal
distribution within the polymer matrix, the characteristics of natural fibers and
composite fibers made of epoxy resin were found to be insufficient. Utilizing an
unprocessed natural fiber ratio of 50% fiber-to-resin, the composites were fabricated by
hand layup technique. The findings showed that the epoxy composite enhanced with
Tamarindus indica fibers (TIF) demonstrated outstanding mechanical properties,
achieving a tensile strength of 8.15MPa and compression strength of up to 5.89 kN. The
compositions of the composites were analyzed using scanning electron microscopy
(SEM) methods.
