“…In reinforcing materials, natural fibers and fillers are extensively studied for their potential to enhance the properties of different matrices. These materials have found applications across diverse sectors, including the automotive, construction, biomedical, electronics, and sports sectors [ 3 , 4 , 5 ]. For instance, major automotive manufacturers like Mercedes-Benz [ 6 ], Audi A2 [ 7 ], Toyota [ 8 ], Mitsubishi Motors [ 8 ] and BMW [ 9 ] have successfully integrated natural fillers with various matrices to produce components such as door panels and interior elements.…”

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

The demand for bio‐fiber composites has increased globally due to the environmental impact of non‐sustainable materials. In this context, Natural fibers are becoming increasingly popular in various applications due to their sustainability. This study explores silane‐treated Mimosa pudica (MP) fibers obtained from the relevant plant that were treated with silane and utilized to strengthen composites used in brake friction development. Five different formulations for brake friction composites were developed using silane‐treated and untreated MP fibers combined with inert filler synthetic barites and maintaining other ingredients in constant amounts. The brake pads were then evaluated for physical, chemical, mechanical, and thermal properties, and their tribological performance was assessed using the chase test, following SAE J661‐2021. The test results revealed that the silane‐treated fibers had a higher cellulose content of 57.2%, while the untreated fibers had a cellulose content of 48.7%. The Rockwell hardness‐K scale value was higher for brake pads made with 5 wt% silane‐treated fibers, with a value of 95. The wear loss was lower for brake pads made with 10 wt% silane‐treated MP fibers‐based brake pads than other composites. Scanning Electron Microscope analyzed the worn surface features of the brake pads used in the Chase test.Highlights Mimosa pudica fibers were utilized as reinforcement in brake pads Silane‐treated Mimosa pudica fibers showed higher cellulose content and improved thermal stability Silane‐treated Mimosa pudica fibers‐based brake pads showed optimal μ and lower wear rate.
