Characterization of Syzygium cumini (L.) Skeels (Jamun Seed) Particulate Fillers for Their Potential Use in Polymer Composites

Molecules, Journal Year: 2024, Volume and Issue: 29(11), P. 2618 - 2618

Published: June 2, 2024

Syzgium cumini (L.) Skeels powder (S. powder), also known as Jamun, is well-known for its various medical and health benefits. It especially recognized antidiabetic antioxidant properties. Thus, S. used in industries, such the food cosmetic industries. In this work, fruit of was utilized; seeds were extracted, dried, ground into powder. The powders subjected to techniques physicochemical tests, Fourier transform infrared (FTIR) spectroscopy, X-ray diffractometry (XRD), particle size analysis, scanning electron microscopy (SEM), energy-dispersive spectroscopy (EDX), thermogravimetric analysis (TGA), differential calorimetry (DSC), analysis. From it revealed that jamun seed filler contained cellulose (43.28%), hemicellulose (19.88%), lignin (23.28%), pectin (12.58%), wax (0.98%). FTIR supported these results. For instance, a peak at 2889 cm−1 observed associated with CH stretching, typically found methyl methylene groups, characteristic structures. XRD results demonstrated crystallinity index 42.63%. indicated mean (average) 25.34 μm. This observation ensured SEM EDX spectrum showed elemental composition fillers. Regarding thermal degradation, had ability withstand temperatures up 316.5 °C. Furthermore, endothermic exothermic peaks 305 °C 400 °C, respectively. property displayed scavenging activity 91.4%. comprehensive study not only underscores viability sustainable effective particulate polymer composites but demonstrates potential enhance mechanical properties composites, thereby offering significant implications development eco-friendly materials industrial applications.

Mechanical and Ballistic Properties of Epoxy Composites Reinforced with Babassu Fibers (Attalea speciosa)

Polymers, Journal Year: 2024, Volume and Issue: 16(7), P. 913 - 913

Published: March 26, 2024

The mechanical and ballistic performance of epoxy matrix composites reinforced with 10, 20, 30 vol.% babassu fibers was investigated for the first time. tests included tension, impact, testing 0.22 caliber ammunition. results showed an improvement in tensile strength, elastic modulus, elongation addition fiber, composite stood out. Scanning electron microscopy analysis revealed fracture modes composites, highlighting brittle fractures matrix, as well other mechanisms such fiber breakage delamination composites. Izod impact also increasing content. In tests, there increase absorbed energy. All surpassed plain by over 3.5 times energy absorption, underscoring potential engineering defense applications.

Ballistic and Electromagnetic Shielding Properties of Epoxy Resin Reinforced with Carbon Black and Jute Fabric

Polymers, Journal Year: 2025, Volume and Issue: 17(3), P. 336 - 336

Published: Jan. 26, 2025

This study explores the development of a multifunctional composite material by incorporating carbon black (CB) into an epoxy matrix reinforced with 30 vol.% jute fabric. The objective was to evaluate impact CB on composite’s tensile properties, ballistic performance, and electromagnetic shielding effectiveness (SE) within X-band frequency range (8.2–12.4 GHz). 5 (EJ30/CB5) exhibited 15% improvements in its strength elastic modulus compared (EJ30) only. Ballistics tests indicated no significant increases absorbed energy or limit velocity, which may be attributed structural rigidity introduced CB. An analysis revealed that addition significantly enhanced SE from ~2 dB neat 5–8 EJ30/CB5, absorption emerging as primary mechanism. findings highlight potential CB- jute-reinforced composites for applications requiring both mechanical robustness interference shielding.
