Characterization of Syzygium cumini particulates filled E‐glass fiber‐reinforced epoxy composites

The biodegradable and naturally available waste Syzygium cumini particulates filled E‐glass fiber laminate‐reinforced composites were fabricated with different weight percentages. The present work is to develop a new composite from huge waste of S. cumini seeds. The two different combinations of composites with different concentration (10, 20, 30, 40, and 50 wt%) of reinforcement were fabricated through open layup molding techniques. Functional groups, X‐ray diffraction, surface morphology, carbon, hydrogen, nitrogen and sulphur (CHNS) elemental analysis, and mechanical characteristics (tensile, flexural strength, and hardness) of fabricated composites were evaluated. The maximum tensile strength, flexural strength, and maximum Shore D hardness of the composite were found to be 14.04 ± 0.5 MPa, 1603 ± 0.5 MPa, and 92 ± 0.5 SHN, respectively. By incorporating E‐glass fiber laminate on both sides of the S. cumini particulates filled epoxy composite enhanced mechanical properties compared with S. cumini particulates filled epoxy composites. The results showed that these composites can be utilized as panels for low strength applications.
