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.

丁香颗粒填充无碱玻璃纤维增​​强环氧树脂复合材料的表征

可生物降解和天然可利用的废弃小茴香颗粒填充 E 玻璃纤维层压板增强复合材料制成不同的重量百分比。目前的工作是利用大量的小茴香废料开发一种新的复合材料种子。具有不同浓度（10、20、30、40 和 50 wt%）的增强材料的两种不同复合材料组合是通过开放式叠层成型技术制造的。对制造的复合材料的官能团、X 射线衍射、表面形态、碳、氢、氮和硫 (CHNS) 元素分析以及机械特性（拉伸、弯曲强度和硬度）进行了评估。发现复合材料的最大拉伸强度、弯曲强度和最大肖氏 D 硬度分别为 14.04 ± 0.5 MPa、1603 ± 0.5 MPa 和 92 ± 0.5 SHN。通过在小茴香颗粒填充的环氧树脂复合材料的两侧加入无碱玻璃纤维层压板，与小茴香相比增强了机械性能颗粒填充环氧树脂复合材料。结果表明，这些复合材料可用作低强度应用的面板。
