“…In the current era scientists are working to create eco-friendly materials to hamper the growing environmental pollution by using biodegradable materials (Zabermawi et al, 2022;Jagadeesh et al, 2023;. However, synthetic polymer composites, due to their functionality, cost-effectiveness, and ease of production, have taken the lead in many industrial and technological applications over the past ten years (Joseph et al, 2023 andBoominathan et al, 2022).…”

In this study, a microcrystalline cellulosic biopolymer (MCB) made from Pisum Sativum (green pea) pod waste via a modified thermo‐chemical process, and Crotalaria juncea (sunn hemp) fibre was used to create environment‐friendly polyester composites. The main objective was to synthesise the MCB from domestic waste and characterize how the addition of hemp alters the strength of the polymeric composite. The MCB was synthesized using green pea pods. The sunn hemp fibres were used in mat form in this study. The composites were made using the hand layup method and post‐cured at 110°C for 2 h. The results showed that the addition of sunn hemp fibre and MCB increased the mechanical properties. Similarly, the highest observed fatigue life count for the composite designated PSC3 (2.0 vol.% MCB) was 30862 at 30% ultimate tensile stress. Similarly, the composite PSC3 had the maximum penetration resistance with an absorbed energy of 14.2 J. Moreover, the addition of silane‐treated cellulose and fibre provided an improved storage modulus of 6.8 GPa for the PSC3 composite, confirming the improved fibre‐matrix fibre interaction and increased toughness. The scanning electron microscope images revealed improved fibre‐matrix correlation. These eco‐friendly composites with better load‐bearing capabilities could be preferred in automated door panels, defence toolboxes, and home interior decoration applications.

“…14 Previous studies reported that the use of inorganic metal-based fillers in modifying composites could improve the flammability and thermal resistance of composites. [15][16][17][18][19] In contrast to the inorganics, more exploration is needed regarding the thermal and fire-retardant resistance of organic fillers. Organic fillers are often used in natural fiber composites due to their environmental benefits over inorganic fillers.…”

Natural fiber composites are not suitable for use in industries due to their flammability and low thermal resistance. Inorganic metal‐based fillers are known to enhance the flammability and thermal resistance of composites, while the thermal and fire‐retardant properties of organic fillers are not commonly known. This study evaluated the mechanical, thermal, and flammability properties of Ceiba petandra fiber (CPF)‐reinforced composites, which were added with snail powder (SP). To study the thermal resistance of the composite, a dynamic mechanical analyzer (DMA) and thermogravimetric analysis (TGA) were applied. SP Filler concentration increased the composite's tensile strength and thermal resistance. DMA test results showed the same trend as the composite's density value. The flame rate parameters of the composite, including the percentage of char yield and the limitation index oxygen (LOI), rose as the SP filler increased. However, the flame rate of the composite dropped because SP filler inhibited the movement of oxygen, combustible gas, and polyester degradation products. The addition of organic fillers in natural fiber composites promises better flammability and thermal resistance.

Sustainable composites are presently employed in applications where structural demands are minimal. Basalt fiber reinforced PLA (BFPLA) and polybutylene succinate (BFPBS) composites, incorporates bio‐based materials, offer the potential to reduce non‐renewable resource consumption and improve end‐of‐life disposal practices. Given the significance of thermal aging in semi‐structural applications and the necessity for open holes (notches) for installation and assembly, little is known about how thermal cycling (TC) affects the open‐hole strength of sustainable composites. This experimental work establishes a quantitative relationship between open‐hole strength and TC, taking into account varying abrasive waterjet pressures, and explores the impacts of thermal aging on the notch sensitivity, thermal, mechanical, and physical properties. BFPBS displayed better unnotched tensile strength and notched strength than pre‐thermal BFPLA specimens after they have been subjected to 100 TC ranging from −20 to 55°C. Thermal aging significantly influenced notch sensitivity, emphasizing its consideration in evaluating notch performance. This research provides a significant contribution to our current understanding of the effects of thermal aging on sustainable composites, enabling their informed application in a variety of industries and the results highlight their promising potential, in particular BFPBS, as strong alternative for medium load applications.Highlights Evaluated thermal aging effects on basalt fiber (BF) composites, revealing improved properties in BF/PBS composites after thermal cycles. Established quantitative link between mechanical behavior and thermal cycling using varying waterjet pressure values. Basalt fibers enhanced crystallinity and thermal stability of PLA and PBS polymers, showing promise for sustainable composites. Notch sensitivity impacted by thermal aging, underlining the importance of considering these effects in notch performance evaluation. BF/PBS composites demonstrated potential as robust alternatives for indoor products and sports equipment.
