“…The fact that fine particles outperformed coarse particles in impact resistance demonstrates how different filler size ranges might contribute to various mechanical behaviors and energydissipating mechanisms. 19,73,85 Hence, these findings significantly affect the composite material design, especially where impact resistance is an important consideration. Furthermore, the significance of proper optimization is highlighted by finding the best filler loading (20 wt%) for the highest impact strength.…”

“…18 It is important to consider, though, that there might be a point at which additional filler loading increases could lead to a decline in tensile properties. 19 Cionita and coworkers examined how filler affects the flexural properties of an epoxy resin (ER)-reinforced composite made of untreated palm kernel cake filler (UPKCF). The results suggest that the maximum flexural strength (FS) and flexural modulus (FM) peak at 30% filler content before dropping to a minimum at 40% filler content as the filler load concentration increases.…”

Creating environmentally friendly materials like polymer matrix composites (PMCs) enhanced with natural fillers has grown in recent decades. It supports the United Nations sustainable development goals (SDGs) by reducing the reliance on non‐renewable resources, minimizing waste generation, and promoting sustainable land and water management practices. This investigation assesses the viability of employing Elaeocarpus ganitrus (rudraksha) seeds as a filler (rudraksha seed filler [RSF] in environmentally sustainable composite materials. Various loading concentrations and sizes of RSFs were incorporated by hand lay‐up into polymer epoxy resin (ER). The effect of filler on the mechanical properties of composites was observed. Thermal properties of RSF/epoxy composites were investigated using thermogravimetric analysis (TGA) and Fourier transform infrared (FTIR). The 10 wt% 100‐mesh filler had the maximum tensile strength (TS) at 42.30 MPa and flexural strength (FS) at 87.4 MPa, surpassing other filler sizes and loading concentrations. Meanwhile, the highest impact properties have been achieved with 20 wt% of RSF with 0.436 J. The results of this study highlight the significant impact of filler type and concentration on the mechanical properties of the material. These findings offer valuable insights that may be applied to various industrial contexts. Furthermore, incorporating 10% up to 30 wt% RSF in epoxy composites has brought more thermal stability than virgin epoxy. It revealed that the RSFs possess higher decomposition temperatures than the epoxy matrix. RSF has a potential sustainable reinforcement in polymer composites and holds great promise for addressing environmental challenges and aligning with several SDGs.Highlights Interest in eco‐friendly materials, like polymer composites with natural reinforcements, has been increasing in recent decades. Rudraksha sees filler is lightweight with low moisture, high carbon content, and some mineral elements. The addition of Rudraksha seed filler has enhanced the tensile, flexural, and impact properties of the composites. Rudraksha seed filler possess higher decomposition temperatures than the epoxy matrix. Rudraksha seed filler has a promising future as a sustainable friction material for automotive brake pads.

“…This was due to the exposure of the RS surface, which is hydrophilic in nature, and the voids present in the surface of the test sample also influenced the moisture uptake [52,53]. After the test sample completely absorbed the water content due to continuous soaking, a saturation point for WA was reached, beyond which the WA rate is marginal [32,54].…”

Managing rice crop stubble is one of the major challenges witnessed in the agricultural sector. This work attempts to investigate the physical, mechanical, and liquid absorption properties of rice straw (RS)-reinforced polymer composite for assessing its suitability to use as an ayurvedic treatment table. This material is expected to be an alternative for wooden-based ayurvedic treatment tables. The results showed that the addition of rice straw particles (RSp) up to 60% volume in epoxy reduced the density of the composite material by 46.20% and the hardness by 15.69%. The maximum tensile and flexural strength of the RSp composite was 17.53 MPa and 43.23 MPa, respectively. The scanning electron microscopy (SEM) analysis showed deposits of silica in the form of phytoliths in various size and shapes on the outer surface of RS. The study also revealed that the water absorption rate (WA) was less than 7.8% for the test samples with 45% volume of RSp. Interestingly the test samples showed greater resistance to the absorption of Kottakal Dhanvantaram Thailam (<2%). In addition, the developed samples showed resistance towards bacterial and fungal growth under the exposure of treatment oils and water.
