“…56 Furthermore, the addition of fillers to the fiber-reinforced composite decreased its void content, which could be due to the coverage of gaps or porous regions of the fiber by the fillers. 57 Filler agglomeration at higher filler loadings can be the reason for increased void content for all the fabricated composites. 58…”

Agro-wastes have a huge potential to be utilized as lignocellulosic reinforcements in polymer composites. This will not only play an important role in waste management but will also strengthen sustainable production. In the present work, pine cones and wood apple shells were utilized as fillers along with areca sheath fibers in bio-based epoxy resin for fabricating a novel hybrid composite wherein the effect of these fillers in laminated composites has not been explored to a greater extent. The impact of reinforcing both types of fillers in different loadings (5, 10, and 15 wt.%) on various properties of composites was investigated. Physical properties like density, void fraction, mechanical properties comprising of tensile, flexural, interlaminar shear strength (ILSS), and hardness along with morphology and moisture absorption behavior of composites were investigated. The mechanical properties of the fabricated composites were influenced by the structure (coarser/finer) of fillers and their chemical composition. The mechanical results for the composites revealed that incorporating wood apple shell fillers resulted in the maximum rise in tensile (23.97%), impact strength (16.81%), and interlaminar shear strength (31.64%), while the incorporation of pine cone fillers resulted in the maximum rise of flexural strength along with Young's (35.4%) and flexural modulus (32.81%). A reduction in moisture absorption was observed on the addition of both types of fillers up to a certain filler loading. The investigations demonstrated a noticeable enhancement in mechanical and physical properties of the fabricated composites on reinforcing micron size fillers.

“…One explanation for this outcome can be the impact of filler loading on the interfacial bonding between the filler and the matrix. According to earlier studies, excessive filler loading can cause agglomeration and reduced interfacial area between the filler and the matrix, leading to a weaker interface and diminished mechanical properties 69–71 . On the other hand, a lower filler loading enables a more uniform dispersion of the filler particles in the matrix, producing a stronger interface and improved mechanical properties.…”

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.

Natural fibres have been partly substituting synthetic fibres in polymer composites due to their renewable character and many other advantages, and sometimes, they can be hybridized into a single composite for a better combination of properties. This work aims to study the effect of hybridization and stacking sequence on the mechanical and physical properties of the glass/jute laminates. For that, pure jute, pure glass and glass/jute hybrids were manufactured by vacuum infusion process using orthophthalic polyester resin. The composites were characterized via C-scan analysis, density, volume fraction of constituents and optical microscopy analyses. Mechanical properties were obtained from tensile, compression and shear tests. The longitudinal properties were higher than transverse properties for all laminates. The hybrids presented intermediate density and mechanical properties compared to pure glass and pure jute laminates. The hybrids produced similar density and tensile modulus, but with small differences in tensile strength and compressive strength which were justified based on variations in resin and void content due to the influence of the stacking sequence (glass/jute interlayer regions). In addition, the pure glass and the hybrid laminates displayed acceptable failure morphology in the in-plane shear test, but not the pure jute laminate.
