“…This is a common phenomenon observed in many natural fibers and PLA as they contain moisture that is vaporized at relatively lower temperatures. The next stage of minor weight loss that was observed in the temperature range of 280–295°C was maybe because of the degradation of hemicellulose present in the plant fiber‐reinforced within the PLA matrix 46 …”

“…The next stage of minor weight loss that was observed in the temperature range of 280-295 C was maybe because of the degradation of hemicellulose present in the plant fiber-reinforced within the PLA matrix. 46 Hemicellulose is a complex carbohydrate that is present in natural fibers and is known to degrade at lower temperatures compared with cellulose and lignin. From the Derivative Thermogravimetric (DTG) curves in Figure 6B, it was noticed that there were not many changes in the midset degradation temperatures of the composites.…”

The additive manufacturing technique represents a technological advancement post the industrial revolution, enabling the development of intricate products with minimal waste. In the automotive sector, polymer extrusion‐based additive manufacturing is predominantly employed for part customization. Recently, reinforced polymer matrices have been used to enhance structural integrity, primarily utilizing synthetic materials. Due to environmental concerns, some recent studies have explored the incorporation of natural fiber reinforcement in polymer matrices for 3D‐printed products. Most research has focused on filler reinforcement, limiting investigations to a single type of reinforcement. To bridge this gap and enhance composite performance, our research introduces a novel method for 3D printing composites. This involves stacking sequences using two different natural fiber‐reinforced polylactic acid (PLA) filaments, namely Nona and Soy, respectively. Mechanical testing reveals that the stacking sequence significantly influences the mechanical properties of the 3D‐printed composites. The 3D‐printed composite with Soy/PLA skin stacks exhibits the highest tensile strength of 74.82 MPa. Thermal analysis shows minor changes in glass transition temperature (Tg) and a consistent degree of crystallinity (10.01%). Notable differences in thermal expansion are observed due to the stacking sequence. Fatigue analysis demonstrates the durability of hybrid composites, enduring over 42,000 cycles with minimal deformation compared with to pure fiber‐reinforced 3D‐printed composites. Morphological analysis reveals excellent fiber–matrix interaction and bonding between stacks. The observations confirm that the developed material can be potentially used for developing structurally enhanced composites for lightweight applications. Moreover, the proposed methodology can be adapted for different 3D printing matrices, including robotic printing with multiple axes, making it suitable for various industrial sectors.Highlights Utilization of 3D printing technology for the development of agro‐waste fiber products. Hybridizing the 3D‐printed composite enhanced the fatigue life. New additive manufacturing technique for developing structurally enhanced composites.

“…Thus, understanding these mechanisms is critical for modifying thermal behaviors in polymer composites for various applications requiring increased thermal stability and specific thermal transitions. 7,23,[26][27][28] Jawaid and colleagues investigated the thermal properties of oil palm empty fruit bunch (OPEFB) composites with varied weight fractions of jute fibers. Decomposition of the hybrid composite (OPEFB/jute) started at a higher temperature (263-286 C) than that of the OPEFB composite alone (260 C), and the final degradation temperature ranges from 433 to 463 C. The final decomposition temperature of the composite is increased by hybridizing OPEFB with jute fibers.…”

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.
