The short palmyra palm leaf stalk fiber reinforced polymer matrix composites are prepared by a compression molding method. The result illustrates that the 7 mm alkali-treated short PPLSF composite exhibited the maximum tensile strength of 45.13 ± 1.57 MPa, the flexural strength of 71.35 ± 2.57 MPa and impact strength 10.21 ± 2.13 kJ/m 2. The dynamic mechanical analysis shows that the 7 mm alkali-treated short PPLSF composite has improved the storage and loss modulus compared to 3 mm and 10 mm short untreated and alkali-treated fiber composites. Further thermogravimetric analysis carried out for 3 mm, 7 mm, and 10 mm untreated and alkali-treated fiber-reinforced composites showed that the thermal characteristics of the composites have improved due to treatments as well due to increase in fiber length. The tensile-fractured surface of the composites is also examined with SEM to identify the mechanism of failure.

Various biocomposite samples with different fiber contents (lengths and loadings) were fabricated, using compression molding process and vulcanizing technique by maintaining the temperature around 150 oC. From the results obtained, mechanical properties: tensile strength, modulus elongation at break and tear strength of 10.44 MPa, 2.36 MPa, 627.59% and 34.99 N respectively, were obtained from the optimum composite sample with length and loading of 6 mm and 20 wt.% composition, respectively. The maximum hardness was observed at 76.85 Shore A from the composite sample of 6 mm and 40 wt.%. The optimum properties can be attributed to the presence of strong interfacial adhesion between the Sansevieria cylindrica fiber and the natural rubber matrix. The mechanisms of failure of the biocomposites at their interfaces were examined and analyzed, using scanning electron microsco...
